XP-Pen Artist 24 Pro: a new hardware to review

Published on


Sorry for weird expression of my cat; he was licking his fur and also curious about the box I put on the table...little photobomb expert!

Hey, look what I just received? A XP-Pen Artist 24 Pro tablet!

XP-Pen sent me this tablet for free in exchange of a video review on my channel. A good (sponsored) opportunity for me to finally test their product (their best product, this is their largest display-pen tablet). So expect to see this review video happening soon. The video review will be on my GNU/Linux system and using Krita. I'll also make a full artwork with it (to be sure I spent enough time on it before emiting an opinion) and I'll publish the video of the timelapse too.

I'm planning to test this model with all the care I usually put testing new hardware on my blog. You'll see detailed report about the driver, the sensitivity of the stylus, the overlay sheet surface, the resolution, the color calibration, the hot spot on the surface, etc...etc... (If you have specific ideas for tests, write them in the comments). I'm the first one interested to see if I can adopt it for my work on Pepper&Carrot: a quadHD (2560 X 1440 pixels) bundled into a 24inch tablet with 90% AdobeRGB colorspace... A good resolution and color space on the paper! and also a monitor with the size big enough to put my comic pages fully visible at print-size. Interesting specs.

I think I'll be able to give a honest feedback about it and turn this sponsoring into useful information for all the digital painter around. If I find bad thing, I'll tell it; if I find good things, I'll tell them too. That was part of the agreement I had with XP-Pen: to have full freedom on this review and that's why I accepted.

(from Wayne's World movie)

In the past, many tablet vendors proposed me reviews but I usually refused because no GNU/Linux driver or support. Not the case this time because XP-Pen does the effort to propose for download a proper list of GNU/Linux drivers for many distros:


Screenshot on their website of GNU/Linux drivers...

It's still not a Free/Libre and Open-Source driver but it's a very good step. I'll also certainly test the tablet with the free/libre Digimend driver.

I'm very curious and excited to try it!

Update: The review:

⚠️ I made a mess while sharing the URL of the article (I shared the wrong one); So, if you catch this message; move to read this article, that's where the review is really posted. Thank you, you can also continue to read here −the copy is identical− but in a week or so; the review will be hosted only on this article URL. and here will remain only a redirection.

Here is my deep review of the XP-Pen Artist 24 Pro on GNU/Linux (Kubuntu 20.04)! The large, 24" QuadHD pen tablet. I'm testing all the part as I could on this video. XP-Pen sent me this tablet for free in exchange of a video review and I want to be transparent about this deal. It was a good opportunity and I had full freedom in our agreement (that's why I accepted). I hope you liked it, I took a lot of passion and fun to make this review. I hope I'll be able to continue to make more in the future!

Updates and Erratum:

You'll find here update of things I discovered after making the video:

[2021-05-11] ERRATUM: Micro-USB instead of USB-C: I spoke about a 'Micro-USB' cable; it's in fact a USB-C cable. Sorry, all this 'mini' USB standards got me confused to name this one correctly.

[2021-05-11] ERRATUM: 65536 level of pressure: The label that appears at 03:24 in the video is inexact: the device has (probably) 8192 level of pressure maximum. By the way; the level are not well distributed as the first 10% of the stylus nib contact will be mostly ignored then from 10 to 30% it will grow super quick and then it require a lot of pressure to reach 100% (not the best default curve to be polite, but one that can be smoothed with driver workaround). I saw tablet with 512 level of pressure having better built-in feeling and sensitivity to low pressure levels. About the erratum; I should have noticed 65536 looks like an address space of 64 KB (65,536 bytes). I noticed that after testing it on other tablet I own in house; all also revealing the same 65536 max number.

[2021-05-10] Perfect match for Ergotron Arm: No surprise, the tablet could really adapt to my Ergotron Arm with the VESA 100x100mm pattern that appears after unscrewing the default stand. The tablet is less heavy than my old Cintiq21UX that was over 10Kg; this one is probably half. Anyway, it requires a bit of adapting the Ergotron to be rigid enough to not move with a weight like that.

[2021-05-09] No magnetic noises with Wacom Intuos4 around: After the review, I connected back my IntuosXL to my Philips 27'' for my production (QuadHD also, near to 100% sRGB, but not perfect but with −at least− the best antiglare and frameless design). I kept the XP-Pen Artist 24 Pro as my second monitor with the Ergotron Arm (ready to be used for a drawing). I was affraid the two tablet would interact; something I already saw with Intuos and Cintiq (especially the one able to share same Stylus). But here; no noise, no shakes; the two tablet are probably set to use distinct frequency; and that's perfect for me.

Install guide:

The guide under is not part of the review 'deal' and a personal work I made to allow you to run your XP-PEN Artist 24 Pro on Linux with the Free/Libre and Open Source driver Digimend. You'll see on the review the proprietary driver has issues; and the worst: being closed/non-free and so we don't know what it does. Remember that while I'm writing this, the tablet is still not officially supported by the Digimend project; and so it require many manual workarounds and post-installation process. But the base main component; the Ugtablet+stylus sensor is recognized.

Limitation: The following guide was written for Kubuntu 20.04 LTS + Digimend driver version 10; it might works as well on any other Xorg/Linux distro with newer version of the driver; but be aware that Fedora/Arch/Ubuntu doesn't store the configuration files at the same place; you'll have quickly to check where it is for xorg.conf.d and hwdb.d to succeed. GNU/Linux distro are fast moving targets; and I don't have any ideas if this might work also in another situation. Use it as your own risk (but it should be fine, and everything here is easy to revert).

I detailed my guide here so non-technical user (artists and Linux beginners) could follow it. I'm also taking the time to not just throw command-lines, but explain why and what it does. For tweaking the configuration files of your tablet, you'll need a text-editor. Here I use Micro. If you don't want to install it, just replace any micro of this article with the default nano text-editor or your favorite.

Install Digimend:

I installed here the version 10 https://github.com/DIGImend/digimend-kernel-drivers/releases/tag/v10 as a Debian package (link finishing by .deb). On Kubuntu 20.04, a simple double-click on the deb will launch the installer. On other 'buntu, I often met distro who doesn't ship this type of Debian package installer by default (how sad). In this case; you can still install them using the command line: sudo dpkg -r xp-pen-pentablet*.deb , Once done, restart your computer.

Add the X11 rule:

If you run lsusb in a terminal, you'll find a line describing your tablet and this listing also give you the address of the device. Mine was: Bus 003 Device 007: ID 28bd:092d Tablet PTK-1240.

So, I created the file 60-xppen.conf in the folder /usr/share/X11/xorg.conf.d/ (you need administrator permission to create that) this way:
sudo micro /usr/share/X11/xorg.conf.d/60-xppen.conf

Once the blank editor was opened, I pasted this inside the editor:

Section "InputClass"
  Identifier "XP-Pen 24 Pro Frame"
  MatchUSBID "28bd:092d"
  MatchIsKeyboard "on"
  MatchDevicePath "/dev/input/event*"
  Driver "libinput"
EndSection

Section "InputClass"
  Identifier "XP-Pen 24 Pro Tablet"
  MatchIsTablet "on"
  Driver "wacom"
  MatchUSBID "28bd:092d"
  MatchDevicePath "/dev/input/event*"
EndSection

This will ask the wacom driver to handle our tablet; you can see the MatchUSBID "28bd:092d" part, very important to target the right tablet (we found this adress with lsusb). I saved, and then restarted the computer again.

If everything wen right, you should see an ouput after typing xsetwacom --list, mine was:

UGTABLET 24 inch PenDisplay stylus      id: 10  type: STYLUS    

Xsetwacom script:

Once the tablet is recognised by the Wacom driver; you can customize only the mapping of the stylus, its pressure curve and the first button of the stylus with it. That's not much compare to what Xsetwacom can do with a full support, but still this is very cool.

If you prefer a graphic interface; the kde-config-tablet was able to handle it (sudo apt install kde-config-tablet, then restart the computer and launch in the system configuration the tablet settings). But here I prefer using a bash script that will apply at each start-up of my system my favorite settings. Each setting is set with the xsetwacom command line.

Here under is my own script; fully commented (line starting by # are not read by computer, so I added a sort of instruction on them). If you paste this script on a text-editor and save it as xppen_Artist-24-Pro.sh (where you want on your disk, mine is on a folder I created for my scripts /home/deevad/scripts and then you'll see this your text editor will show with color what are important lines, and what are just comments.

Don't reuse the script under as it is, it will not work. You need to read it and adapt it to your system. Especially the part about mapping it to your monitor xrandr identifier, and you might need to calibrate with xinput-calibrator

After saving it, you'll need to right click on the file > Properties (Permission tab) and activate "Is Executable" checkbox and press OK. Once your script is ready, you can run it by double clicking on it. This customisation will be lost at every restart of your computer (not the script, only the effect). If you want to run it automatically; just add the script to your 'Autostart' (type autostart in the menu; Plasma has a nice interface for that with a button "Add Script" ).

xsetwacom --set "$tabletstylus" RawSample 1 # data pt.s trimmed, default is 4, 1-20

If you managed well, the tablet stylus mapping and pressure of the XP-Pen Artist Pro 24 should work on Mypaint, Blender, Gimp, Inkscape, etc...

Testing with Xinput

If you want to test your stylus; run at first xinput to get an identifier of your stylus. Here is mine:

UGTABLET 24 inch PenDisplay stylus        id=23

Then launch with customising the "id" (23 here):

xinput test 23

Once you'll draw on the monitor, the terminal will report all the events of the stylus.

Udev/Hwdb rule for second button on the stylus and other buttons.

Customizing the second stylus button of the XP-Pen Artist 24 Pro (the one on top) was my top priorities. I created a Udev/Hwdb rule to simulate a right click after catching the event. To do so, create a Udev/Hwdb custom rule with sudo micro /etc/udev/hwdb.d/90-xppen.hwdb and paste this:

evdev:input:b0003v28BDp092De0100-e0*
 KEYBOARD_KEY_d0045=0x14c

You can find how I found the identifier of the tablet device b0003v28BDp092De0100-e0* (complex and different for every devices) thanks to the entry on the Arch Linux wiki about udev that describes the method to retrieve one. To test the custom rules, save the file; and run the one-liner under to recompile and restart Udev. The change should be instant without needing it to reboot.
sudo systemd-hwdb update && sudo udevadm control --reload && sudo udevadm trigger

If you want to customize the button to another key, 0x14c is a keyboard scancode. You can find a list of Keyboard scancode here; it will give you the last two number/letter for the key you need to target.

The tablet buttons (on the frame) by default behave like a keyboard and send events that were pre-recorded by XP-Pen (call them 'hardcoded'). They aren't that bad. It's possible to edit some of them. Thanks Jbigler on Github who described the events, I'm copy/pasting their great description of the default key under:

Left side:
01. b             70005 / code 48 (KEY_B)
02. e             70008 / code 18 (KEY_E)
03. alt           700e2 / code 56 (KEY_LEFTALT)
04. space         7002c / code 57 (KEY_SPACE)
05. ctrl+S        700e0 / code 29 (KEY_LEFTCTRL) + 70016 / code 31 (KEY_S)

LDL: ctrl+-       700e0 / code 29 (KEY_LEFTCTRL) + 70056 / code 74 (KEY_KPMINUS)
LDR: ctrl++       700e0 / code 29 (KEY_LEFTCTRL) + 70057 / code 78 (KEY_KPPLUS)

06. ctrl+z        700e0 / code 29 (KEY_LEFTCTRL) + 7001d / code 44 (KEY_Z)
07. ctrl+alt+z    700e0 / code 29 (KEY_LEFTCTRL) + 700e2 / code 56 (KEY_LEFTALT) + 7001d / code 44 (KEY_Z)

09. v             70019 / code 47 (KEY_V)
10. l             7000f / code 38 (KEY_L)

Right side:
11. ctrl+o        700e0 / code 29 (KEY_LEFTCTRL) + 70012 / code 24 (KEY_O)
12. ctrl+n        700e0 / code 29 (KEY_LEFTCTRL) + 70011 / code 49 (KEY_N)
13. ctrl+shift+n  700e0 / code 29 (KEY_LEFTCTRL) + 700e1 / code 42 (KEY_LEFTSHIFT) + 70011 (KEY_N)
14. ctrl+e        700e0 / code 29 (KEY_LEFTCTRL) + 70008 / code 18 (KEY_E)
15. f             70009 / code 33 (KEY_F)

RDL: [            7002f / code 26 (KEY_LEFTBRACE)
RDR: ]            70030 / code 27 (KEY_RIGHTBRACE)

16. d             70007 / code 32 (KEY_D)
17. x             7001b / code 45 (KEY_X)
18. ctrl+delete   700e0 / code 29 (KEY_LEFTCTRL) + 7004c / code 111 (KEY_DELETE)
19. ctrl+c        700e0 / code 29 (KEY_LEFTCTRL) + 70006 / code 46 (KEY_C)
20. ctrl+v        700e0 / code 29 (KEY_LEFTCTRL) + 70019 / code 47 (KEY_V)

So, you can only switch a key for another one; and shortcut with two two or three key will be limited to shortcut using also three keys. Note also if you want to switch Ctrl for Shift; all your Ctrl+something shortcut will switch for Shift+something. So, it's limited, but possible to customize with a little bit of thinking.

All of that are Udev/Hwdb rules as described on the previous chapter about customizing the second button on the stylus. ( on sudo micro /etc/udev/hwdb.d/90-xppen.hwdb )

Here I'm sharing the B of the brush on first key ( 01. b) for a 01. Shift to resize my brush with: KEYBOARD_KEY_70005=0x2a

The second one, 'e' is ok for the eraser toggle of Krita, so I'm keeping this one.

Third is a 'Alt'; not usefull for me. I'll replace with a '&' symbol; something I can remap on Krita ( I use it with the '10 preset plugin' , to switch to a brush preset; here in my case, an eraser. You can see the method in my video about keyboard shortcut on Krita. ) KEYBOARD_KEY_700e2=0x02

I keep the default spacebar; useful to pan document.

Debatable: I'm switching all Ctrl key to null event... because Ctrl+s, Ctrl+q (to quit; on Azerty keyboard the Ctrl+Z of default is switched for a Ctrl+Q). KEYBOARD_KEY_700e0=unknown

I'm switching the 's' alone for a 'z' (a 'w' because this is qwerty to azerty) KEYBOARD_KEY_70016=w

All in all , here is my Udev/Hwdb file with the stylus (sudo micro /etc/udev/hwdb.d/90-xppen.hwdb):

evdev:input:b0003v28BDp092De0100-e0*
 KEYBOARD_KEY_d0045=0x14c
 KEYBOARD_KEY_70005=0x2a
 KEYBOARD_KEY_700e2=0x02
 KEYBOARD_KEY_700e0=unknown
 KEYBOARD_KEY_70016=w

Run a sudo systemd-hwdb update && sudo udevadm control --reload && sudo udevadm trigger to refresh after saving your file.

Misc:

Calibrate the QuadHD display

Here is a one liner to calibrate your color on Ubuntu 20.04 tablet with argyllCMS (I used here a Pantone Huey Pro calibrator):

dispcal -d 1 -t 6500 -b 160 -g 2.2 -v -o $(date +%Y-%m-%d)_XPPEN24PRO

Here is a summary of the option so you can spice it to your needs:

  • -d 1 for monitor 1.
  • -t 6500 for the temperature, to target 6500K.
  • -b 160 for 160 cd/m² brightness.
  • g 2.2 for a gamma at 2.2.
  • -v verbose mode, print more information during the process.
  • -o $(date +%Y-%m-%d)_XPPEN24PRO the output filename (here with a auto iso date prefix).

If you are a bit lost with this options; you can still let ArgyllCMS default decides for you with simply:

dispcal -d 1 -v -o $(date +%Y-%m-%d)_XPPEN24PRO

Once you have the ICC file; you can apply using the color interface setting of Plasma/KDE; or you can apply it by command line with:

dispwin -d 1 /home/deevad/scripts/2021-05-11_XPPEN24PRO.icc

You'll get the list of your monitor with dispwin -help and you can add that to a bash script and launch that at startup (see the method detailed on xsetwacom chapter of this article).

Note: If you don't have any calibrator, your best setting with the OSD of the tablet might probably be to keep the Gamma at 2.2, the brightness at 60 and the Color mode to sRGB.

Fix IntelHD Gfx card not recognising the QuadHD resolution:

On my laptop with a IntelHD integrated chipset for graphics I ran for test, the maximum resolution detected was a 1920x1200... Note this card wasn't enough performant to run Krita on this tablet without any noticable lag. If you connect this tablet to a computer, I advice you to get a performant one!

I case you run into this issue; you can fix it with by checking how is named your output (often named by xrandr after the name of the cable/plug) ; mine for this laptop was HDMI-1; you can do so with the command xrandr and then, run this:

cvt -r 2560 1440

The output gives:

2560x1440 59.95 Hz (CVT 3.69M9-R) hsync: 88.79 kHz; pclk: 241.50 MHz
Modeline "2560x1440R"  241.50  2560 2608 2640 2720  1440 1443 1448 1481 +hsync -vsync

Perfect! it is the specifications you need to add to a custom new xrandr profile: So, write:

xrandr --newmode "2560x1440R"  241.50  2560 2608 2640 2720  1440 1443 1448 1481 +hsync -vsync
xrandr --addmode HDMI-1 2560x1440R
xrandr --output HDMI-1 --mode 2560x1440R

And success, your XP-Pen Artist 24 Pro should switch after that to 2560x1440 quadHD resolution.

Fix the XPPEN proprietary driver

In case you are OK with using the proprietary driver (I'm not, but in this case, don't install the Digimend one) and this one doesn't work ( tested on xp-pen-pentablet_3.1.0.210331-1.x86_64.deb, 30 April 2021) ; it means the installer failed at giving permission in post-install. You can fix it simply with:

sudo chown $(whoami) /usr/lib/pentablet
sudo chmod +x /usr/lib/pentablet/pentablet

Hey ! I am a new french artist (bonjour à vous ! ^^), I have the "deco pro" model but when I tested it on linux (few mount ago, a new one as been published now) the driver have only one good point... it's exist... it was very bad.
work pretty well on windows, so I used it on windows, I am pretty curious to see your test on the xp-pen driver !
the digimend driver too, even if my model it's not supported by it. ^^

PS in french : Votre travail et votre philosophie m'inspire énormément et j’espère me diriger sur la même voie à l'avenir ! (désolé si je suis trop formel avec le vouvoiement ^^)

link David REVOY Author, - Reply

Thank you very much for your kind words! 😊 Merci merci
Yes, I 'll try to see how it is now. If it is too woobly with the official driver; I'll try to follow the dev documentation of Digimend to add support (not sure I'll have the skill; but I already put a toe in it with the WH1409 Huion years ago).

I switched from a XP-Pen Artist 13.3 to the Deco Pro for ergonomic reasons, but i was disappointed about the Deco Pro because i noticed delays in the brush strokes what disturbes me a lot. So i end up in a Gaomon M106K Pro, what its really a pity, because i like the Pen and the Tablet Design from the Deco much more. Did you have comparsions to other tablets? Maybe iam just unlucky about my device (?) ...

link Ratorix   - Reply

I usually use the stroke latency of krita now so can't see it, but I have just tested it and I have no delay on my stroke (stroke latency off).
So, you probably have some issues on yours.
I dont have my Intuos one with so I can't test it with another tablet.

I started with an old bamboo fun by wacom (the white one) and after that an Intuos pro M, wacom too.

Compared to the last one (even if a lot of years separate it with the deco pro), I can say that the deco pro it really a good tablet.

I only can see three issue with it :

- no eraser on pen (wacom pen have it)

- too many type of tip, no standard so no special one (I use eraser-like one on my intuos)

- not the best driver, especially on linux

However it's not so bad and the driver become better with time.

I'd also be very interested to see how well this works for sculpting and painting in blender on GNU/Linux

Good reminder. I'm not as fluent in Blender as I was on the Sintel days; but last animation of Pepper&Carrot (for book release) was done using Grease Pencil. So, I'm also interested to see the compatibility with Blender; I guess I'll not try to sculpt something; but I can test if I can deform a 3D potatoe and see if pressure and coordinate works well.

Looking forward to your experience with this tablet. I never use a cintiq so iam always snoopy if the Artist Pro Series is in some way compareable. The price from xp-pen tablets are really attractive. What i just miss from the specs is that they have no VESA connection for a monitor arm (or at least a own product like the Wacom Flex Arm, but i would prefer VESA because the Wacom Flex Arm is just overpriced for his function).

Please strong critic no open source driver. If company open source driver, often people find bug and fix it and help work with more Linux distro, save time and money for every person. No reason hide driver code because company sell hardware.

Your cat's expression explains how awesome the Xp-pen going to be. :D

I look forward to the video review. I've been thinking about upgrading my Cintiq 13HD especially on Linux OS, too.

Hi!

I'm really curious about your review results

I currently have a XP-Pen Artist 13.3v2
There's 2 things I'm curious about the model you'll test:
- How is parallax? not noticeable? highly noticeable? On my XP-Pen Artist 13.3v2, there's a huge parallax (from my point of view, it's about 1mm between nib on screen and screen display I think)
- How are the drivers :)

Currently, I don't use XP-Pen drivers.
I don't know if they've been improved, but last time I used them (when I bought the tablet 2 years ago) it was more a simple software with very few options you have to execute to be able to use tablet than a driver installed on system (close XP-PEN software windows was stopping the possibility to use tablet)

I had to manage a specific and a little bit complex Linux configuration to be able to use all tablet functions (you can find my explanation here if you're interested in:

Hi Grum999,
Thanks for the feedback and sorry for the late reply,

"How is parallax?"
It is noticable, and classic. I would say a bit more than on Cintiq13HD, and less than on Cintiq21UX. Similar or a bit less than Cintiq22HD. Here I manage to always calibrate the cursor so it is not under the tip (I offset it on the bottom left of the tip to see it); so I'm rarely affected by a bad parralax.

"How are the drivers"
Hehe, I hope the video replied to this question :)

I feel bad because I read your thread only now (thanks! very informative) and I feel I reinvented the wheel. You'll see my solution is really near; but your udev script looks really better. I'll read in detail. Thanks for sharing!

Coucou David !
Joli cadeau que tu as eu d'XP Pen, wooow ! Je vais certainement regarder la vidéo dès que j'en ai la notification ! Par ailleurs, je voulais te remercier pour tout ce contenu inspirant que tu partages ! C'est grâce à toi que j'ai décidé de persévérer en dépit des moyens financiers limités que j'ai pour dessiner sur le plan digital !
Et j'ai aussi une question personnelle, pour une tablette à écran, j'ai eu un débat avec quelqu'un qui me disait que 8000 niveaux de pressions c'était obligatoire. Tu en penses quoi? Parce que je vois pas mal de tablettes à 2000 niveaux de pressions, et je trouve ça tout à fait correct pour ma part, donc je me disais que ça pourrait être suffisant? J'ai besoin de l'avis d'un expert xD
Bonne journée !

Bonjour Jérémy,
Merci pour les mots sympas. Par rapport au débat; je viens d'une époque ou les tablettes avaient 512 ou 1024 niveau de pressions. Et honnêtement, ça n'a jamais été un problème. On est vraiment face là à la cellule marketing qui c'est accroché à un chiffre dont il était possible d'incrémenter pour faire 'plus gros chiffre' = 'mieux'. Avoir plus de niveau de sensibilité, c'est toujours mieux; mais au final , pour le logiciel de dessin; c'est une fraction allant de 0 à 1 pour toutes les tablettes. Et beaucoups de logicielles vont arrondir après la virgule, ou appliquer une selection des évenement (filtering/trimming) ou bien du smoothing de coordonnées. Bref; je considère que toute tablette avec au minimum 1024 niveau de pression = OK. Le problème réelle; c'est combien de milligramme de pression sur la pointe enregistre le point 0. Et si 10 pressions de 0% à 100% sont répartis de manière linéaire; ou si on presse comme un bourrin et la pointe n'enregistre que 80% ; ou bien si en effleurant, la pointe n'enregistre que 0%.
Comme métrique intéressante pour les tablettes, il y aurait aussi la résolution de la matrice de coordonnée (jamais specifié) dans le cas de cette XP-Pen 24 Pro, c'est 32767 32767 unité. Un carré pour décrire un champs en 16:9; pas commun. Ma petite Intuos4Medium de voyage avec son A5 enregistre à elle seule 44704 27950, ma Cintiq 13HD 59152 33448 ... Plus de résolution! Ma Intuos4 XL: 97536 60960! On est clairement sur le double de résolution (c'est pour ça que j'aime sa sensibilité).
Voilà, je crois donc que la pression c'est un faux débat et que ceux qui ne jurent que par ça sont bien receptif au discours commercial et publicitaire... (j'imagine qu'il y a un effet placébo du 'ça dessine mieux'). J'éspère que c'était intéressant.
