18

This happens in two different computers, one with Ubuntu 20.04 and another with 18.04.

The left 40% of the tablet maps horizontally to the entire monitor, while vertically it works fine - bottom to top in the tablet is bottom to top in the monitor. The remaining 60% of the tablet is unused. Both computers are dual boot with Windows 10 and the tablet works fine in both.

Is there a way to map the entire tablet area to the entire monitor?

I tried configuring the Wacom tablet using the settings in Ubuntu. I chose tablet absolute and relative, I clicked "map to a single monitor" in the option Map to monitor.

I tried xsetwacom in command line. Following these instructions:

https://ubuntu-mate.community/t/scale-your-wacom-tablet-to-a-single-monitor/8036

I tried setting:

xsetwacom --get "Wacom Co.,Ltd. Intuos S stylus" area
0 0 15200 9500

If I change it to a larger horizontal value:

xsetwacom --set "Wacom Co.,Ltd. Intuos S stylus" area 0 0 30400 9500

The tablet area remains unchanged, but the pen does not go to the horizontal end of the monitor. If I change it to a smaller number (smaller than 15200) then the tablet area where the pen is "active" is reduced.

I also tried:

xsetwacom --set "Wacom Co.,Ltd. Intuos S stylus" MapToMonitor eDP-1

where eDP-1 is my monitor name from typing xrandr.

Thanks for any help!

Update

There is a weird behaviour here. If I switch on my computer with the tablet already plugged in, it works fine! If I plug in the tablet after the computer is on, the problem reported above happens.

If, when it is working fine, I disconnect the tablet and then connect again, the problem above also happens.

    Are you using two monitors? – bashBedlam Jul 01 '20 at 23:50
  • No, I have only one monitor in both computers (one is a desktop, the other a laptop). – Chicoscience Jul 01 '20 at 23:56
  • I updated my question. I found a weird pattern. – Chicoscience Jul 02 '20 at 00:22

    I also get the same issue. I use two monitors, but that seems irrelevant. Only the first roughly 40% on the left works, while the vertical works flawlessly. Even mapping with an offset has no effect on the rightmost part of the tablet. No issue on Windows. It seems like a driver problem. – Signal Jul 03 '20 at 18:19

Hold the left-most and the right-most buttons until the LED turns off and back on.

    Amazing! Perfect, not only solved the problem but also taught me about the Android/PC mode! – Chicoscience Jul 04 '20 at 20:11
  • This fixed the issue for me as well! Weird little problem for Ubuntu users – Jordan Pagni Sep 09 '20 at 22:25
  • Wow!! this worked as a charm! – ram0nvaldez Sep 11 '21 at 01:04
  • Thanks for the info! I have the same problem, however, when I switch to PC mode (by holding the 2 buttons) Ubuntu then stops registering my Intuos at all. Any idea? – J-J Feb 11 '22 at 22:45
  • The vendor ID will change in lsusb, make sure you can still see it. Is it wired or Bluetooth? I suggest you open an issue on their GitHub: https://github.com/linuxwacom/xf86-input-wacom – Signal Feb 13 '22 at 02:31
