affects ubuntu/xserver-xorg-video-nv
I get garbled screen colours when using an NVIDIA/XFS GeForce 8800GS video card with the xorg nv driver in Lucid. The 190 nvidia drivers from the nvidia-vdpau PPA work fine, although they seem to randomly reset my machine (another bug that I haven't fully tracked down yet.) The NVIDIA 180 drivers in karmic also work fine, and do so for hours at a time without any screen garble, which leads me to believe that this is not an overheating problem.
The nv driver for karmic works fine with the card in question. The card I have has 2 DVI inputs. I get garbled colours both via DVI -> VGA adapter and VGA cable to monitor, and DVI cable direct to the monitor's DVI port. Photo taken from my phone is attached to show whats going on, as well as lspci and xorg log. No proprietary NVIDIA drivers, either in X/userspace, or kernelspace are installed or loaded.
Thank you for reporting this issue about xserver-
with Lucid, Ubuntu is transitioning to using the -nouveau video driver
by default instead of -nv. The reason for this change is because
upstream development for the -nv driver has been quite slow. We are
quite pleased with the upstream development speed for -nouveau, and hope
this will translate into swifter bug fixes as well.
Because of this, I'm closing this bug report at this time. I'm marking
it wontfix because what you describe is probably a valid issue, but we
do not have further plans to work on it in Ubuntu. If you would still like
to see this issue investigated, I would encourage you to file it
upstream at http://
