Hello,
Today morning I tried to get gdm working on my laptop with ubuntu karmic, I really miss it (xsplash is quite restrictive).

I followed the instructions in the document and I pasted all (from "select all" til the last dot "."). But when i restarted the system it was not working.

Then I used a diferent display e.g. "ctrl+alt+F2" and wrote this:
username (u'r username)
password (u'r password)
Enter
change to "ctrl+alt+F7" to watch what's hapening on display 2
return to "ctrl+alt+F2" to type

sudo apt-get install gdm
password
y
Enter

and then when it is instaled you can choose between gdm-2.0 and gdm.

Then reboot.
I got everything working as it was in the begining ("unfortunately with xsplash again")
if anybody knows and can tell me what happened with my computer and the script i will be grateful with him.

I hope this was understandable and I've helped somebody who teared off his pc.

This sounds awesome I can't wait to try it. I don't even have multiple users I'm just a customization whore.

You've done it again.
