Hello,
since one and a half years I’ve got a notebook with manjaro installed (actual 22.04) with gnome desktop.
I’m experiencing intermittend touchpad stops working issues. The rest of the system is still functional.
I recognized the touchpad disappears from lsusb list.
I sent the notebook to service, but they did not find a problem.
in dmesg I recognized the touchpad reregisters repeatedly as different input until it stops working.

reboot resolves the issue.
I’ve got a dual boot system, I’m not sure if the issue also appears in Windows as I’m working 0,01% with Windows. May it happened once in Windows but I’m not really sure. This would mean it will be an hardware issue. Using Manjaro it could reproduced quickly.
It mostly appears during multi-touch input and multitouch could reproduce this issue very quick.
Thanks for tips and suggestions.
