Comment 7 for bug 274290

It's not an exact duplicate of #272877.

Changing the driver (with alpha6) to vesa or ati gives a correct picture for approx. 1 second - after that the screen turns black. If I use ati the screen disappears after moving the mouse.

I attached the log - first change was to vesa, after that to ati. Starting gdm always gives a [failed] although the picture is visible for an instant.
