If that _does_ work, try from gfxterm then. Nope, it doesn't make any difference. What seems important is the "vga" option on the kernel command line. If I leave it out then I see the console (using either terminal_output console or gfxterm).

Hi again, I'm uploading 1.96+20090629-1, which includes some cleanup in the Linux loader. It's possible your problem might disappear with this version, please report. Note: Try it in text mode first (run "terminal_output console" in GRUB prompt). If that _does_ work, try from gfxterm then. Note2: If you can't wait, the patch you want is: svn diff -r 2372:2375 svn://svn.savannah.gnu.org/grub/trunk/grub2 Thanks! -- Robert Millan The DRM opt-in fallacy: "Your data belongs to us.

Hi,
Since I'm unable to reproduce this, I will need some help. I need you to
boot a modified Linux image with the "linux16" loader, e.g.:
linux16 /boot/bzImage
boot
and then tell me the output (if you're using the older version of GRUB,
linux16 won't be present, in that case use "linux" instead).
You might be able to get it through a serial port with console=ttyS0
parameter, but I'm not sure if that will work at this point in the boot
process. Otherwise, use pencil and paper!
The patch you need to apply to Linux is attached. If it's more practical
to you, you can use this prebuilt image instead:
http://people.debian.org/~rmh/bzImage
which is gpg-signed:
http://people.debian.org/~rmh/bzImage.sig

Bug#534944: grub-pc: text mode virtual terminals blank
Package: grub-pc
Version: 1.96+20090628-1
Severity: normal
I'm seeing the same behaviour, the problem appeared after upgrading from
1.96+20090603-2.
I do not auto-start the graphical login screen (i.e. the system is configured
to stay in text mode), so the problem seems unrelated to X. The kernel is
configured to use vesafb, but not output is displayed (grub menu itself is
fine).
