I have recently changed my graphics card to quadro fx3700, before I had nvidia 9800gt. After the upgrade I have experienced random screen blackouts during intensive use like during playing Trine 2 or watching online videos.

I have tried many driver versions from ubuntu repo and also from xorg edgers but nothing helps. I habve also upgraded to the lates xorg and kernel stack from sausy.

Also my pc is connected to a phillips TV not a monitor - maybe this is the cause? Before the upgrade this was not an issue..

Any thoughts? Cheers

Have you checked out this Wiki article? Sections near the bottom deal with video cut-out. –  douggro Mar 11 at 14:00
