--- Comment #9 from Eric Valette ---
I had a chance to look at the display on the tv set after my kids went to bed,
here is whar happens:
1) I get on long black immediately after boot as if normal vga display does not
work,
2) Once init is completed, I see the kdm loggin,
3) I see the begining of kde initialization and at one point the screen goes
black,
4) After a GPU rest I see for one second the normal desktop,
5) screen goes black forever
Looking at the dmesg, I have a pile of until it fails to reset I guess
