** Description changed:
Binary package hint: linux-image-2.6.26-3-generic
After grub selection there is no any output to screen till gdm start.
This happens if VESA mode selected in grub command (vga=792 for example). VGA modes work well.
This problem exists only in 2.6.26-3 kernel.
As I can see kernel had switched to uvesafb from vesafb.
There is another bug (https://bugs.launchpad.net/ubuntu/+source/linux-
meta/+bug/189621) about missing v86d, which is needed for uvesafb to
~$ lsb_release -rd
Description: Ubuntu intrepid (development branch)
$ uname -a
Linux astar-laptop 2.6.26-3-generic #1 SMP Wed Jul 2 21:56:15 UTC 2008 i686 GNU/Linux
GeForce 8400M GS installed on my laptop.
+ ( this workaround is similar as in comment #42 )
+ 1) install v86d
+ 2) create /etc/modprobe.d/uvesafb
+ options uvesafb mode_option=1280x800-32 mtrr=3 scroll=ywrap
+ 4) append
+ blacklist uvesafb
+ to /etc/modprobe.d/blacklist-framebuffer
+ 3) append
+ to /etc/modules
+ 4) run
+ update-initramfs -u
+ 5) reboot.
