I had googled the page before , and it not works for me .

I have try this several day before and try again just a few minutes .

it not work .

when I add vga=788 to the line of defoptions
, I can see the grub screen ,but no matter I add vga=*** to the kernel line
not .,when the kernel boot up it got a black screen.

when vga=791 to the defoptions line . the grub screen can not be seen , no
even say the terminal screen.

I am quite sure my computer support 1024 768 solutions. since when I used
dappar last year , the vga=791 option can work well for my laptop.

I do not know where goes wrong .

thanks for your help .

appendix is the article , and I have try the A step .

6. Configure GRUB: A MUST FOR Dapper Drake (6.06)!

Open you GRUB configuration file.

gksudo gedit /boot/grub/menu.lst

To proceed, you'll need to know the framebuffer code for your desired












   *Automatic (and update-proof) GRUB Configuration*

Find the line

# defoptions=quiet splash

and add your framebuffer resolution code, e.g. (for 1024x768)

# defoptions=quiet splash vga=791

(Don't "uncomment" the line - it only works when it is "commented".)

Save the file, then execute

sudo update-grub

This will now keep even after any future kernel update, unlike the method
below. You're all done.


   B. *Manual *
