On 12.04 64-bit, about every 5 seconds my screen blinks twice. Even during installation of Ubuntu from CD, this happens during the complete process.
I had no problems with earlier Ubuntu versions (earlier version was 10.04LTS 64-bit)
- MSI 7681 Motherboard
- 16 GB RAM
- 2 x Nvidia 560 card SLI (only 1 screen on 1 card active during install process)
This flickering is driving me crazy, please help.
