main screen flickers every 10 seconds.
Hi I have no problem with Ubuntu 13.04, Full Monty, Linux Mint and several other distros,but when running Ubuntu 12.04 LTS, linux snow, mageia 3 and others the main screen flickers every 10 seconds. Apart from this the graphics operate perfectly.
I have dual monitors and the 2nd screen does not flicker at all.
I have tried changing the screen resolution and refresh rate but the flicker continues.
Any ideas what causes this or how to resolve it please. thanks
