Fixing Bad Plymouth Resolution
For some newer System76 computers using Ubuntu 10.04 LTS, users may notice problems with Ubuntu's new Boot Screen program called Plymouth. In particular, the resolution of the boot screen may be very low, and this may cause it to look bad. The following fix is fairly invasive, but should fix any problems you are having with your boot screen.

gksudo gedit /etc/default/grub
Then click on "Run". You should get a text editor window. At the end of the file, enter the following:
Now, save and close the file and open a terminal (Applications > Accessories > Terminal). Enter the following command:
And press Enter. Wait for the command to finish running, then close the terminal and reboot.
On some systems this may cause Green Artifacts around the Ubuntu Logo. This is a side effect of using plymouth for boot, and is hard to fix. If you really want them gone, see Fixing Green Artifacts
