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.

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?
