Screen cut off during bootup / when in tty

My bootup messages and agetty are cut off on the left. I can fix this by adjusting my monitor, but then xorg winds up cut off on the right. I'd like to be able to switch between tty's without constantly adjusting my monitor. Any tips?

Re: Screen cut off during bootup / when in tty

You could try changing the resolution or refresh rate in /etc/X11/xorg.conf, or perhaps Horizontal Sync (I'm not familiar with that one, but sounds like it could help). I had a problem of my monitor not displaying when I switched out of X, complaining of an unsuitable resolution. Putting the allowed resolutions in xorg.conf,

SubSection "Display"
        Viewport   0 0
        Depth     24
        modes "1280x1024" "1024x768" "800x600" "640x480"
        Virtual 2560 1280
EndSubSection

within the 'Section "Screen"', fixed that for me.

You could try to set the Grub resolution.

sudo nano /boot/grub/menu.lst

You'll see lines like:

kernel /boot/vmlinuz-2.6.17-10-generic root=/dev/sda5 ro quiet

Add vga= + the correct vga code to set the resolution. Here you can find some vga codes: http://www.linuxquestions.org/blog/arch … -lilo-830/

So as example, I want to set the resolution to 1024x768 with 16.7M colors, you get:

kernel /boot/vmlinuz-2.6.17-10-generic root=/dev/sda5 ro quiet vga=792

Hope it helps.
