Thanks to zektor in the Kororaa forums for posting this fix. It is reported on RPMFusion’s Bugzilla and nvnews.net.
The 300.x.x series NVIDIA driver (currently beta) has a bug which causes some newer GPUs to have a blue tinge on the screen. In Kororaa, Jockey installs this latest version.
If your card is supported by the previous version, you can downgrade to this to solve the problem, then lock yum so that it doesn’t upgrade to 300.x.x series.
Remove existing:
sudo yum erase *\nvidia\*
Downgrade version:
sudo yum install akmod-nvidia-295.53-1.fc17.1 \
xorg-x11-drv-nvidia-libs-295.53-\*.{x86_64,i686} \
xorg-x11-drv-nvidia-295.53-1.fc17 \
nvidia-settings-1.0-18.fc17 \
nvidia-xconfig-1.0-16.fc17
Lock version:
sudo yum install yum-versionlock
sudo yum versionlock akmod-nvidia-295.53-1.fc17.1 \
xorg-x11-drv-nvidia-libs-295.53-\*.{x86_64,i686} \
xorg-x11-drv-nvidia-295.53-1.fc17 \
nvidia-settings-1.0-18.fc17 \
nvidia-xconfig-1.0-16.fc17
Now you can reboot your machine.
