howto force resolution at boot?

**sentofuno** · 06-13-2006

hi

i use a kvm, and sometimes when i boot my machine the kvm will be switched to another machine. if i don't switch it over to my ubuntu box during boot i can only get 640x480 rather than 1280x1024. i need a way to force the proper res every time as the 'make default' option doesn't work in the preferences settings.

thanks

Try with appending
vga=1280x1024
to the grub entry.

edit your

Code:

/boot/grub/menu.lst

file as root
go to near the bottom, and on the line that looks like

Code:

kernel          /boot/vmlinuz-2.6.16-1-k7 root=/dev/hda1 ro

add vga=1280x1024 so it looks like

Code:

kernel          /boot/vmlinuz-2.6.16-1-k7 root=/dev/hda1 ro vga=1280x1024

Are you sure you edited the correct entry? I have many grub entries. Try adding vga=1280x1024 to every line that begins with 'kernel'.
