Comment 8 for bug 278146

Same symptoms at least on gdm login. I couldn't test it further because shortly after the flickering X dies and GDM restarts. Even if I try to change to console with ctrl + alt + f1 I only see vertical colored and black bars and can't do anything except of changing back to the X slot. I have tested it with todays daily live cd.
That's why I haven't posted more information. The intel driver was one of the best X drivers but it gets worse and worse with every release. First problem was the textured video which doesn't work really because of tearing, then the flickering and now the dying. Last ones seem to be an i915 problem but video watching is annoying in Intrepid even with other Intel graphic cards and according to manpage it isn't possible to activate Overlay without changing the source. Not to mention the great performance loss.
And btw. the greatest part is to just closing the upstream bug report without fixing anything.
I will post more debug information soon but it is really annoying and time consuming. It is fine if it leads to a better driver but atm. it doesn't seem so.
