Sorry, I'm new to this business, but I'll try and open a new bug report. Meanwhile, I tried with "failsafe graphics mode" and got exactly the same result: after the progress bar finishes, I see a blinking underscore for a second, the screen flickers once or twice, then goes black. I was able to switch to another VT and get the Xorg.0.log, which doesn't show any errors; gnome appears to be running properly. I attach the Xorg.0.log and the output of lsmod.
