After upgrading to 12.04, the Plymouth bootsplash screen isn't present. Instead I get a text based version. How can I get the higher-resolution graphical Plymouth bootsplash back?

What does your /etc/default/grub file say? There should be a line that starts GRUB_CMDLINE_LINUX_DEFAULT=. What is the entire line? –  Chan-Ho Suh Apr 15 '12 at 8:32
    
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash reboot=pci acpi_backlight=vendor" –  Luke Hoersten Apr 28 '12 at 2:16
    
It looks like you've modified your Grub config. Could you post all of it? Also, are you using the proprietary nvidia driver? –  Chan-Ho Suh Apr 28 '12 at 23:38
    
hpaste.org/67855 - yeah I'm using the proprietary nvidia driver. –  Luke Hoersten Apr 30 '12 at 0:18

Hi Luke. I took a look and see nothing amiss (unfortunately). The usual problem with the Nvidia prop driver is that the Plymouth splash is the wrong/low resolution, but in your case, it can't even boot in a lower resolution, which is odd. Anyway, the usual way of fixing the former is to uncomment #GRUB_GFXMODE=640x480 and set it to the appropriate resolution. So that might work for you too.

To uncomment a line in a configuration file like /etc/default/grub--which is the file to be modified in this situation--remove the # at the beginning.

After modifying /etc/default/grub, the command sudo update-grub must be run, to apply the changes.
