I've just upgraded to a new monitor, that has a default resolution of 1920x1024. How do I set Grub2 and consoles to use 1920x1024? Right now I can't use any console (Ctrl-Alt-F2). I'm using Ubuntu 10:04 x86_64.

Thanks,

Correction. The resolution in 1920x1080.

If I use startup-manager to change the boot display and boot loader menu to 640x480, I then have a working console (Ctrl-Alt-F2) but at 640x480 only. Nothing higher works. But at least I have a console now. And in X, 1920x1080 seems to work well.

Set the desired resolution in "/etc/default/grub", like this:

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1920x1080
GRUB_GFXPAYLOAD_LINUX=1920x1080Then run:

sudo update-grubGreetings.

^This, plus add 'uvesafb' with the appropriate options to /etc/initramfs-tools/modules if it doesn't already work, and update-intitramfs.

You mean something like this, right?:

Yeah, might be necessary. But the OP should definitely try the simple way first.
