Cannot map Wacom tablet to single display via GNOME settings
Affected version
- OS: Arch Linux (up to date as of 08/16/2020)
- Affected GNOME Shell version: 3.38.1
- Issue appears in XOrg. Not tested on Wayland.
Bug summary
In a multi-monitor setup, plugging in a Wacom tablet maps the surface area of the table to the union of all the displays. Selecting "Map to single monitor" in the Wacom tab of GNOME settings has no effect. This is not a XOrg or kernel bug, since the directly mapping the tablet to a single screen via xsetwacom
works. This bug was introduced in GNOME 3.38; on GNOME 3.36, "Map to single monitor" works as expected.
Steps to reproduce
- Plug in a Wacom tablet.
- Observe that the tablet's surface area gets mapped to the union of all the active displays.
- Go to the Wacom section of GNOME settings.
- In the "Tablet" tab, click on the "Map to monitor" button. On the popup, select "Map to single monitor".
What happened
The tablet's surface area was still mapped to all the displays, and not just one.
What did you expect to happen
I expected that the tablet's surface would get mapped to the selected display.
