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
