No, alt + sys + k and b don't work >> In some games, it takes longer than others. For exemple, in Tremulous, with >> all graphic >> options to the lowest, I can sometimes play tens of minutes.

My feeling is that it even freezes faster with this one but it's probably no more than a feeling. >> My card is an Intel 950 and my computer is an MSI 662-S3. >> > > It's actually an Intel 945, see below :) But it's advertised as 950.

It doesn't seem to happen after several minutes running glxgears.

SSH from another computer doesn't work either
