Steam Controller mouse not working in OpenSUSE Tumbleweed
I've changed to the Steam client beta channel and updated the firmware of the controller and the puck, but I can only use the Steam Controller as a regular gamepad on OpenSUSE Tumbleweed KDE.
The touchpads have no function before starting Steam. When Steam is running, the touchpads still don't work, they move some sort of invisible cursor on the Steam window but not anywhere on the rest of the desktop. There's also no way to control games with the touchpads. The sticks and buttons work fine for playing games. I never get the KDE popup that an application wants to control my mouse cursor.
I have Bazzite on my laptop where all these problems disappear. I can control the mouse with the touchpads, even when Steam isn't running. This seems to be an OpenSUSE-specific problem.
Does anybody have similar problems? Are you using a different distro and it works?
EDIT: The following has worked for me while running Steam. Without Steam the touchpads still do nothing
sudo zypper in extest extest-32bit
sudo usermod -a -G input <username>
# reboot to apply usergroup changes
