Hi, Several months ago, you reported a bug to the Debian BTS regarding a crash of the X server with the nv driver. Did you reproduce this problem recently? With the latest xserver-xorg-core 1.3 and xserver-xorg-video-nv 2.0.2 from unstable? I don't see any backtrace in your logs, there should be one in the server is crashing. Thanks, Brice
