My problems appear more or less related. I upgraded to Intrepid beta from Hardy a few days ago. My Compaq Evo D510 (external HDD install) has an Intel 845 graphics card. Compiz no longer works after the upgrade from Hardy to Intrepid (see my other reports 283056 and 284461), so I removed Compiz for the time being. Screen flickering is not the biggest problem and most of the time I can log on without problems. But when I (or any other user of the machine, for that matter) log out from the Gnome session (at the moment, I'm using only Gnome and Fluxbox as another option) I get just a black screen, hearing the default login sound but no login screen, just a black screen with a very minimally flickering texture — I mean it is not as simply "black" as for instance the virtual terminal background. In order to continue (to shut down or to do anything), I must drop into a VT (Ctrl+Alt+F1). In both /var/log/gdm/0:log.1 and Xorg.0.log.old you can see the error "(EE) intel(0): underrun on pipe A!" several times.

My xorg.conf information looks as plain as this:

Section "Monitor"
