Bildschirmflackern bei einem Account
Hallo zusammen,
nach dem heutigen Update meines Systems habe ich bei meinem
"Haupt"-Account plötzlich ein Bildschirm-Flackern.
Starte ich mit einem niedrigeren Kernel, bleibt das Flackern bestehen.
Das Flackern taucht bereits auf dem gdm-Anmeldebildschirm auf.
Wechsle ich jedoch zu einem anderen User-Account, ist kein Flackern
festzustellen.
Kann mir jemand auf die Sprünge helfen, wo ich hier nach dem Fehler
suchen soll? Zwar habe ich schon diverse Themen bei Google gefunden,
aber entweder ist meine Suchstrategie total falsch, oder ich stehe
sonstwie auf dem Schlauch...
Danke für jede Hilfe
Rudolf
