From time to time the mouse pointer disappears and terminal switching with Ctrl+Alt+FX is no more possible. Num Lock may or may not work. See at the attached log files. Installed from Mageia x11-server-xorg-1.20.4-7.mga7.

I see a ton of batch submission errors followed by a graphics error, likely leading to engine hang. It seems you're using plasma, which uses GL to render things and is probably a trigger for these.
Seems to be a kernel related issue since I have booted Debian 9 where it used to work with the Mageia kernel and no mouse pointer appeared.

Created attachment 145905 [details] xfce: Xorg.0.log Now I have tried it with Xfce. It should not use glx. For KDE I believe you cannot switch it off completely, at least not for the logout.

Hmm, there is not much in the logs. Run X with gdb?
