For weeks now I've been unable to enable both Xinerama and Composite in Debian using the latest nVidia drivers (1.0.9631) and Xorg (7.1.1). When I do so, nothing appears on any screen aside from the wallpaper, although screen elements which update periodically do flicker at each update, and right-click menus do the same.
For reference, I'm running a GeForce 7600GT, and I've tried multiple versions of the nVidia drivers, both from nVidia and the Debian repos. Also, logs turned up no clue as to why this is happening, or what causes it for that matter.
I used to use this setup on Kubuntu Edgy and loved it. Could the team please find time to investigate this?
