Разрешене консоли в Debian.

I didn't care about the splash screen, so I just tried a tiny part of the instructions: I added vga=791 to the kernel line in /boot/grub/menu.lst and rebooted into a 1024 x 768 text console. That was it.

The number to give to the vga option depends on the resolution and color depth you want:

Colors        | 800x600   1024x768   1280x1024

256     (8bit)|   771        773        775
32K    (15bit)|   787        790        793
65K    (16bit)|   788        791        794
16.7 M (24bit)|   789        792        795

This is my entry in grub's menu.lst:

title           Debian GNU/Linux, kernel 2.6.8-2-686 @ 1024 x 768
root            (hd0,0)
kernel          /boot/vmlinuz-2.6.8-2-686 root=/dev/sda1 ro vga=791
initrd          /boot/initrd.img-2.6.8-2-686
