I'm actually booting a Debian LiveCD and want to change the screen resolution to console mode, otherwise the letters are too large.
Thank you.

does not change on the fly, only through kernel parameters at boot. like this is added: vga=791

Depending on which fb driver you have, for uvesa it is enough to directly register the resolution in the kernel startup parameters, for example For
kernel /boot/bzImage root=/dev/hda3 video=uvesafb:[email protected],mtrr:3,ywrap
vesa it is prescribed by vga mode, here is the table en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers
kernel /boot/bzImage root=/dev/hda3 video=vesafb:mtrr:3,ywrap vga=792
