Moinz,
vielleicht noch interessant:
Neu angelegte User haben dieses Problem nicht. Dabei habe ich diesen genau wie den ersten User eingerichtet. Im Vergleich einiger Configurationsdateien, bsp für x11 und NVIDIA, konnte ich keine Unterschiede feststellen - was nichts heißen mag, da ich von den Grafik- Treibern nicht wirklich Ahung habe.
Daher hier folgende Infos und den NVIDIA Report im Anhang
