Ubuntu – Wacom Intuous tablet not mapping to single monitor

multiple-monitorstabletwacom

After a recent kernel upgrade, I lost the use of my Wacom tablet (Wacom Intuos Pro Pen and Touch Tablet, Large). I used to use the tablet together with Xournal++ to take notes for my online lectures. From September up until ~October 15, the tablet and pen worked perfectly. I would be able to map the tablet to a single monitor/display. I use three monitors/displays: the laptop screen, one connected via the USB-C port, and the third via the HDMI port). The tablet was mapped to the one connected to the HDMI port.

Now, since the latest kernel upgrade (5.4.0-52 64-bit kernel on Ubuntu 20.04 LTS, GNOME version 3.36.3), I am unable to map the tablet to a single monitor/display (any of the three). As a result, and since I use three monitors/displays, all that I write is stretched three times in the horizontal directions making it impossible to write or draw anything that would make sense to my students.

I have tried several times the different options in the Settings > Wacom Tablet > Tablet menu. I even tried all possible combinations but no success.

Any and all help is appreciated. Please let me know if you need additional information about the setup to help me debug.

EDIT: The selected answer works. To help check the name of the device I used xinput and looked for the line with the line with stylus in it.

Also, to get the coordinates for the offset, or use the display name to map directly to the desired display, I used xrandr. More information may be found here.

I found a bug regarding this Problem here.

the Problem seems to be with the display output names. For me the Workaround with setting the output manually with worked:

xsetwacom --set "Wacom Intuos Pro S Pen stylus" MapToOutput 1920x1080+0+0

Well, I actually had to change the numbers around a bit, because, the aspect ratio and position of my desired display are different. But as a temporary workaround, while they are working on a solution this is OK for me.

the general idea with the numbers at the end is: <width of projection>+<height of projection>+<offset x>+<offset y> for me it was 3400x1440+3840+0

When you are using a different tablet, you might get a message, like this: Cannot find device 'Wacom Intuos Pro S Pen stylus'.. I was lucky enough, that I just had to switch out the S for an M (so the string was Wacom Intuos Pro M Pen stylus for me) but I don't really know where to look for the value you have to use here, when using a different product.

I hope it helps.

EDT: I forgot: I'm using Ubuntu 20.04.1 LTS (with kernel version 5.4.0-52-generic). I'm not so sure on whether or not it's the same for other distros, but yeah, still hope, that I at least notched you in the right direction.

Ubuntu – How to map wacom correctly to monitor

First, determine how your system recognizes your tablet.
In a terminal enter: xsetwacom --list devices

Wacom BambooPT 2FG 4x5 Pen stylus id: 10 type: STYLUS
Wacom BambooPT 2FG 4x5 Finger touch id: 11 type: TOUCH
Wacom BambooPT 2FG 4x5 Pad pad id: 12 type: PAD
Wacom BambooPT 2FG 4x5 Pen eraser id: 17 type: ERASER

Next determine which display or "output" to map your tablet to in your systems display settings or in the terminal with xrandr --listactivemonitors
on my system that shows:

0: +*HDMI-2 1920/521x1080/293+1600+0 HDMI-2
1: +HDMI-1 1600/443x900/249+0+0 HDMI-1

Finally, using the information you just gathered, use xsetwacom --set "[YourWacomDevice]" MapToOutput [your display] (repeat for each device listed ).

[YourWacomDevice] = device name or id:#

so, for me that would be

xsetwacom --set "10" MapToOutput HDMI-2
xsetwacom --set "11" MapToOutput HDMI-2
xsetwacom --set "12" MapToOutput HDMI-2
xsetwacom --set "17" MapToOutput HDMI-2

Since these settings aren't kept after a reboot, you may want to save them in a script that runs on startup.

Using xsetwacom --help lists possible options and commands. With the --list parameters command, we can see a list of all the supported parameters. Near the end of that list is MapToOutput - Map the device to the given output.

man xsetwacom will display it's manual entry or you can read it here

Thanks to @RyanWC and @user1355 for pointing me in the right direction.

You need to adjust the X server's pointer acceleration options for the device. The Wacom driver stopped providing its own (redundant/crude) acceleration options all the way back in late 2009.

There are three pointer acceleration options of interest that can be adjusted at runtime with the xinput utility:

$ xinput set-int-prop <device> "Device Accel Profile" 8 <int>
$ xinput set-float-prop <device> "Device Accel Constant Deceleration" <float>
$ xinput set-float-prop <device> "Device Accel Adaptive Deceleration" <float>

You can see the current values of these and other device properties by running xinput list-props <device>. You'll may notice a "Device Accel Velocity Scaling" property in the output as well -- this knob doesn't do what you might think and should generally be left alone. (For the curious: it should be set to 1000.0/ExpectedRate where ExpectedRate is the rate in Hz at which the input device sends events; the Intuos tablets send touch events at ~100Hz).

To speed up your pointer, first try decreasing the "Constant Deceleration" value. If necessary, you can make it less than 1. At some point this should cause the cursor to move fast enough. If you loose the ability to position the cursor precisely with slow movements afterwards, try increasing the "Adaptive Deceleration". If no amount of tweaking seems to let you both move the pointer quickly across the whole screen and move it slowly in a small area, you should try reseting both properties to 1.0 and then changing the acceleration profile.

These options are more fully documented in the man pages (run man xorg.conf and search for the "POINTER ACCELERATION" section, or try reading this online copy). You'll definitely need to experiment to find a good setting, since it's more than just a single "faster/slower" knob.

Once you find the settings you like you can either save the commands to a script that you can run whenever you want, or create an "xorg.conf snippet" which will automatically apply the settings whenever the tablet is connected. Such a snippet might look like the following and be saved as "/etc/X11/xorg.conf.d/90-wacom-overrides.conf":

Section "InputClass"
    Identifier "Wacom Tablet Overrides"
    MatchDriver "wacom"
    Option "AccelerationProfile" "<int>"
    Option "ConstantDeceleration" "<int>"
    Option "AdaptiveDeceleration" "<int>"
EndSection

Note that it is possible that the desktop environment may override settings specified in xorg.conf.d. If this happens, you may have to use the script instead.
