LXDE runs fine. However, TDE is unstable and already during the setup wizard the screen goes blank after a few second, then comes back, goes blank again and after a few times X crashes and goes back to the login screen. With LXDE, I have a similar issue if I use a openGL application that displays atoms as spheres (other representations work fine). In that situation, the screen also flashes a few times and the application that I use crashes, but the LXDE session survives. This makes me think that it is probably related to the video card not beeing correctly supported by newer kernels. The video card is: Mesa Intel 965GM. I wonder whether anybody has any idea how to troubleshoot this, especially as everything else seems to work fine.
It's not Trinity's or openSUSE's fault: https://bugzilla.opensuse.org/show_bug.cgi?id=1212696 Q965 with modesetting DIX GPU HANG Problem exists in Debian too. https://gitlab.freedesktop.org/xorg/xserver/-/issues/1593
Make sure the xf86-video-intel rpm is installed and its provided intel DDX display driver in use to avoid the problem. As TW kernels do not have the problem, the backport kernel-default labeled as Leap lp155 may work as well: http://download.opensuse.org/repositories/Kernel:/stable:/Backport/standard/x86_64/
