Comment 11 for bug 30631

That should be as an option in the bootloader (GRUB).

In /boot/grub/menu.lst:

Look for a line like this: (Generic example from http://techrepublic.com.com/5100-10877_11-5590770.html# , do not use)

root (hd0,0)
kernel /vmlinuz ro root=/dev/hdc5 vga=788
initrd /initrd.img

the vga= is where you set the graphics options, if there is no vga=, you can add it. I believe vga=788 is a setting you can use for compatibility with different monitors.

Before you change your menu.lst, I'd suggest trying it out first by opening up GRUB when your computer boots, and editing it there in the loader. Setting it there will only apply once, and is good to test, and will not leave you "stranded".
