Bug ID: 512843
Summary: Ability to disable specific touchpad/other input
device in a Wayland session
Classification: Plasma
Product: kwin
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
We have a PS4 controller, which has a built-in trackpad. Unlike Windows, it
actually works as a trackpad. This is pretty great, most of the time! You can
operate your desktop with it, click start buttons, that sort of thing.
But if you map it in Steam Input, it still works as a trackpad, and sends BOTH
mouse clicks and steam input stuff. This makes total and complete sense, of
course, but you can work around it by doing this:
xinput --disable 'Sony Interactive Entertainment Wireless Controller Touchpad'
(the name is slightly different if you're using it over bluetooth. --enable
turns it back on again.)
This presumably doesn't work at all on Wayland. Can we get a way to disable and
reenable specific input devices, xinput style or through the systray or
something?
One important thing here is that it's not a setting that you have to go dig
into a settings page to turn on and off; that would be extremely annoying when
you want to go from using your desktop to playing a game. A settings option
could also be useful for people who don't want to use the trackpad as a
trackpad ever, though.
STEPS TO REPRODUCE
1. Attach PS4/5 controller.
2. Play game.
3. Try to use trackpad. It works both as a mouse and as whatever you assigned.
4. Try to disable it.
OBSERVED RESULT
There is no way to disable the trackpad, at least that I'm aware of.
EXPECTED RESULT
There should be some way to disable the trackpad, without also disabling any
attached mice, or even other trackpads (if you're on a laptop). Even if it
requires a terminal command, that'd give parity with X11 here.
SOFTWARE/OS VERSIONS
Operating System: Debian GNU/Linux 13
KDE Plasma Version: 6.5.3
KDE Frameworks Version: 6.20.0
Qt Version: 6.9.2
ADDITIONAL INFORMATION
I haven't actually tried finding a way to do this on Wayland, we're on X11 for
other reasons too (bug #456697 primarily). If it's already possible and not too
onerous, great!
