It also appears as "unwanted log-out" as soon as the DPMS screensaver or standby mode blanks the screen. After moving the mouse/ hitting the keyboard, the screen reappears and a previous session is gone, instead I am back at login.

(II) AIGLX: Suspending AIGLX clients for VT switch
After this one, X crashes as soon as it is required again. Attempting to disable DRI and/or GLX did NOT HELP anyway...
