Bug#541273: grub-pc: vga= kernel command line option has no effect when grub runs in console mode

Package: grub-pc
Version: 1.96+20090808-1
Severity: normal


  Hi,

  When I set GRUB_TERMINAL=console in /etc/default/grub (by uncommenting the
relevant pre-existing line), my vga=792 option to the kernel stops working.
Upon investigation, I found out that I can make it work again by adding the
following to the relavant menuentry:

	insmod vbe

  However, this is (a) completely undocumented and (b) not easy to automate,
beyond editing the scripts in /etc/grub.d directly.

  I am running the latest version of the grub-pc package, i.e. I
grub-install'ed it. Thanks for providing the reportbug hook; I would have
missed it otherwise. :^)

  If this issue could be addressed in some way, it would be much appreciated.

Regards,
Vasilis
