HelloIt looks like the log I sent was from a X server as restarted by xdm after the original X server crashed.
I get similar error when I do not configure any framebuffer and thus get no console (I'm booting from efi) and try to start X.
Hopefully I will be able to collect the crashed server log later.So far I had two crashes, and both were while the xscreensaver hack Popsqares was displayed.
Thanks Michal
