I installed ubuntu 12.10 in a pc with nvidia geforce fx 5900, only supported by nvidia driver 173. The package nvidia-173 in the repos don't support xorg 1.13 (https://bugs.launchpad.net/ubuntu/+s...3/+bug/1064192) like the newest official nvidia 173 version here http://www.nvidia.com/object/linux-d...36-driver.html . I installed it, but i've 3d desktop issue, on unity (blank screen and pointer) and gnome shell (desktop with freezed folders with no action possible, and working pointer).Absolutely no problems with 2d desktops like gnome with no effects and cinnamon 2d. Direct rendering are ok and the driver seems to be installed right. Unity/Xorg/Driver/Kernel issue?
