I have these kernels installed:

kernel- <- this one is fine!

The last two use what seems to be the full resolution of my screen, except when I expect the graphical login screen to appear, I either get nothing or some odd effect with white lines near the top of the screen. Switching to vt2 shows me a cursor flashing so fast that it would kill an epileptic.

Deleting the xorg.conf file (which s-c-d created) "solves" the problem!

Ugh what a pain. It's not choosing the right video mode any more. I'm getting 1024 x 768.

Tested with:

To make things worse, switching vt to text mode shows the correct resolution, switching back to gdm shows nothing at all any more ("no signal detected").
