Fix xsplash not displaying on Ubuntu 10.04

For OpenSource Drivers
sudo su
echo FRAMEBUFFER=y > /etc/initramfs-tools/conf.d/splash
update-initramfs -u
exit

For Proprietary Drivers

Step 1: we must edit the /etc/default/grub file.

Open a terminal and paste this:

$ sudo gedit /etc/default/grub

On line #18, uncomment (uncomment = remove the “#” in front of the line “#GRUB_GFXMODE=640×480” and change the resolution to whatever you want (in my particular case, I changed it to 1680x1050). Here is how it should look:

GRUB_GFXMODE=1680x1050

Step 2: edit the /etc/grub.d/00_header file.

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

And find the following line: “gfxmode=${GRUB_GFXMODE}” (it’s line 103 on my computer) and under it, paste this:

set gfxpayload=keep

Step 3: update Grub 2:

To update the GRUB, simply run the following command:

$ sudo update-grub
