my debian install has 2 week max.
I have made :
apt install xserver-xorg-input-mtrack
and replace the code in /usr/share/X11/xorg.conf.d/40-libinput.conf.
systemctl restart sddm, made logout.
after that, the touchscreen not working at all. The mouse still working.
if i restore the 40-libinput.conf and loging again, it works normaly.
An idea of problem ?
edit :
there is a file 50-mtrack.conf in same directory. Maybe help.
edit 2 :
i have made "hard mode" with compilation, the problem is not solved. Just the file 50-mtrack.conf has disappeared.
