Modify Ubuntu boot resolution

Note: Only tu11.04 and 11.10 are tested and passed.

Step 1:Open the terminal and modify the/etc/default/GRUB file.

$ Sudo gedit/etc/default/GRUB

Cancel the comments before # grub_gfxmode = 640 × 480, and change the numbers to a proper value, such as 1024x768. This value affects both the grub Startup menu and the text resolution in the console.

Step 2:Modify the/etc/grub. d/00_header File

$ Sudo gedit/etc/grub. d/00_header

Press Ctrl + F to find the keyword "set gfxmode =$ {grub_gfxmode}" (remove double quotation marks), and then add a new line under this line. The content is: "Set gfxpayload = keep" (remove double quotation marks)

Step 3:Update grub

$ Sudo Update-grub

Reboot

Done!
