Public bug reported:
The following issue has started since upgrade from feisty to gutsy
gibbon:
After GRUB, the screen goes black and nothing shows up. The harddisk
seems to be active, so i assume it's booting. But nothing will show up,
this black screen stays.
The workaround i've found is to use ALT-F1 to go to console 1, which
shows up immediately. Then by pressing ALT-F7 the gdm login screen shows
up within ~3 sec. This also confirms my assumption that it does boot in
the background. From the gdm login screen, everything seems to work
correct.
I'm using a Sony Vaio VGN-A115Z notebook, dmesg output:
