How do I get grub to stick to 80x25 text?
On Debian, Ubuntu etc, edit /etc/default/grub and
1. un-comment the line:
2. optionally comment out the line starting with:
(i can't remember if this is required or not. I think it isn't)
3. save & exit, run "update-grub"
On non-debian machines, dunno. probably fuck around with files in /etc/grub.d/
BTW, for kvm you might also want to enable a serial console. I usually enable
two serial consoles per VM, one to log the VM's boot up to a text file on
the host, the other for console access with 'virsh console' (this is also
virtualisation wrapper systems). Remember to actually configure both grub and
a getty (via inittab or systemd) to use the serial console as well as adding
the console "hardware" to the VM.
