[Bug 551290] Re: plymouth theme ugly on binary nvidia driver

[Yann]

On a 7600Go (Toshiba p100 laptop), a variant of #87 worked:
1) Allow FB for initramfs:

echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash
sudo update-initramfs -u

2) Checking highest (highest resolution and color depht) FB mode supported by hardware (requires hwinfo):
sudo apt-get install hwinfo
sudo hwinfo --framebuffer

3)  Edit grub conf file to set selected FB mode:
sudo gedit /etc/default/grub 
Change GRUB_CMDLINE_LINUX_DEFAULT and add "vga=" with FB selected mode nb
Save and:
sudo update-grub

Reboot to check if it work

For instance on my machine:
sudo hwinfo --framebuffer

Returned:
02: None 00.0: 11001 VESA Framebuffer

  Config Status: cfg=new, avail=yes, need=no, active=unknown

So highest FB supported mode is 0x318 (Hexa) = 792 (Decimal), thus in grub config:
GRUB_CMDLINE_LINUX_DEFAULT="splash vga=792"

Did the trick...

Maybe this could be automated for proprietary installs by grub setup or
update process, if this prove reliable by other users.

Please note that GRUB_GFXMODE modification did not have any effect for
me, so this was still commented in my grub config...
