The trouble with KMS

2010/07/05

Kernel Mode Setting in Ubuntu 10.04 is a superb thing when it work.

What KMS gives:
* Flicker free switching from X to terminal (using CTRL-ALT-F1)
* Nice full resolution boot logo

What bad side-effects it gives some computers:
* Suspend/Hibernat not working
* Open GL only in software mode (Slow)

Here is how to disable it:
sudo nano /etc/default/grub

Then look for the line
GRUB_CMDLINE_LINUX=””
and change it to
GRUB_CMDLINE_LINUX=”nomodeset”

sudo update-grub

That’s it!
