Spots appear in a rectangle area on screen, ubuntu gnome 13.04, nvidia driver
- by frozen-flame
I am using Ubuntu Gnome 13.04 with nvidia-310 driver installed. My GPU is GeForce GTX650. Strange spots freqently appear on screen, with following traits:
Spots are restricted in one or two rectangle areas at any instant.
When typing, the pattern of spots change. Possibly increase, or all disappear when one key pressed. Mouse movement also influences.
This problem last within one boot. The only way can I get rid of this problem is to reboot. It can be detected as soon as entering desktop if it appears. Simultaneously, the "power off" option is lost in the top-right menu of Gnome3.
Never such problem when using windows 7 on the same computer, neither ubuntu with Nouveou driver.
Seldomly, half of the screen become black.
I googled a lot. Similar conditions are described, but no confirmed solution. Uninstall-r
einstall strategy does not work.
Any clue solving this will be appeciated.
