Comment 7 for bug 777212

Sorry, in my description above there is an important point missing:
It is necessery to add "i915.modeset=1" as a further kernel parameter after "splash" (in the Grub2-line which starts with linux /boot/vmlinuz...) This starts the graphic driver for intel graphic devices.
Again, one should add this to the /boot/grub/grub.cfg - file...

Here is the corresponding part of my own grub.cfg-file:

menuentry 'Ubuntu, mit Linux 2.6.38-8-generic' --class ubuntu --class gnu-linux --class gnu --class os {
 recordfail
 insmod part_msdos
 insmod ext2
 set root='(/dev/sda,msdos5)'
 search --no-floppy --fs-uuid --set=root 2bb691c9-...
 linux /boot/vmlinuz-2.6.38-8-generic root=UUID=2bb691c9... ro quiet splash i915.modeset=1 vt.handoff=7
 initrd /boot/initrd.img-2.6.38-8-generic
}
menuentry 'Ubuntu, mit Linux 2.6.38-8-generic (Recovery Mode)' --class ubuntu --class gnu-linux --class gnu --class os {
 recordfail
 insmod part_msdos
 insmod ext2
 set root='(/dev/sda,msdos5)'
 search --no-floppy --fs-uuid --set=root 2bb691c9-...
 echo 'Loading Linux 2.6.38-8-generic ...'
 linux /boot/vmlinuz-2.6.38-8-generic root=UUID=2bb691c9... ro single
 echo 'Loading initial ramdisk ...'
 initrd /boot/initrd.img-2.6.38-8-generic
}
