I recently built a Debian "Wheezy" system, which booted via GRUB to a non-framebuffer console, printing

Console: colour VGA+ 80x25

during boot. To /etc/default/grub I added


giving me the boot messages:

vesafb: mode is 1920x1200x16, ...
fbcon: VESA VGA (fb0) is primary device
Console: switching to colour frame buffer device 240x75
fb0: VESA VGA frame buffer device

But when I installed and booted Xen, it reverted to the non-fb console. /dev/fb0 isn't present under dom0.

How do I enable a framebuffer console under dom0?

(Note that this question is not about virtual framebuffers for a domU. There is no domU yet.)

This is for grub-common 1.99-27+deb7u2, xen-system-amd64 4.1.4-3+deb7u3. The motherboard is a SuperMicro A1SRi-2558F, with an Aspeed AST2400.

  • Your phrasing implies that there's a problem with doing so anonymously. It's fair to ask why you're being downvoted, but it's best to leave the scorn out of it.
