I recently installed Ubuntu and also installed the nvidia drivers from (http://www.nvidia.com/object/unix.html
)... everything works ok when i first boot, however when my laptop with its GT240M video card hibernates to HDD, or when i log off, the device has a shimmering effect on screen. I did multiple reinstalls both of Ubuntu as well as Kubuntu and i'm still having this effect.
Can anyone help me? I'm a linux newb, but i'm guessing it has something to do with the xserver restarting?
