Grafikfehler. Was tun?

[Djingle]

Hi,

Ich habe gerade mein Ubuntu (Gutsy Gibbon) gestartet, und was sehe ich da? Viele Grafikfehler.
Es sieht so aus als würde er die Treiber meiner Grafikkarte nicht richtig laden. Auch Anwendungen reagieren langsam oder gar nicht.
Ich habe eine ATI Radeon X1950pro mit dem fglrx (?) Treiber. Hat immer alles wunderbar geklappt.
"glxgears" zeigt die Zahnräder die sich sehr sehr langsam und alles andere als flüssig drehen. Außerdem gibt es

Xlib:  extension "XFree86-DRI" missing on display ":1.0".
511 frames in 6.1 seconds = 83.200 FPS

aus.
Eine Eingabe von "fglrxinfo" ist nicht möglich, da mein Bildschirm daraufhin schwarz wurde und ich mich erneut anmelden musste.
Bin irgendwie ratlos.
Kann mir jemand helfen?
Danke,

Djingle

Hast du die Treiber neu installiert? Welchen Treiber hast du in der xorg.conf eingetragen?

meine xorg.conf:

Habe die Treiber vor ca. 4 Wochen installiert als ich mein Ubuntu neu draufgepackt habe. Wie gesagt -> Hat alles wunderbar funktioniert. Bis jetzt. Habe auch meines Wissens nach nichts an den Einstellungen geändert..
