Blank console with vga=791

[Fabio Marzocca]

With latest kernel update in Breezy (2.6.12-9-386), I lost my console video
output. Nothing is displayed in console during boot or shutdown, not even in a
single-user session. I don't use usplash. This is my cat /proc/cmdline:

root=/dev/hda6 ro console=tty0 vga=791 quiet splash

If I remove vga=791, I get the video output with usplach, but I need small
characters, so I get rid of usplash.

I have also tried on another machine with this /proc/cmdline:
root=/dev/hdb6 ro vga=791

Same result. The screen is completely black during boot and if I go single-user
(telinit 1) I can't see anything.

If you select the previous kernel in GRUB, does it work? Do you have usplash
enabled in that kernel?

[Fabio Marzocca (thesaltydog)]

If I select previous kernel (-8) it DOES work. I was not using usplash either
with the old kernel. Always vga=791. But booting kernel -8 I have the booting
sequence on screen. Booting -9 I don't see anything. Just black. And it keeps
black also in single-user mode or while shutting down. Can't be a kernel flag
change before building the new image?

Does it work with any other video mode?

Can you upgrade initramfs-tools to version 0.29, then "sudo dpkg-reconfigure
linux-image-2.6.12-9-386", reboot and see if that clears up your problems?

[Fabio Marzocca (thesaltydog)]

OK!
New initramfs-tools has fixed the problem. Now I have my console back.
