(Using LiveCD at the moment)
Hi! I've been happily using Ubuntu 9.10 on my 5-year-old Dell desktop for just over a month. I've learned some cool stuff by lurking and searching on these forums and other Linux websites.

Now I've screwed something up.

I had tried KDE for a while to get the feel of Kubuntu, and then went back to my Gnome desktop. I discovered I still had the KDM as my default desktop manager and I wanted to change it. Somewhere I read that I just needed to edit etc/X11/default-display-manager to read

/usr/bin/gdm (instead of kdm) and that's what I did.

When I rebooted, I saw this (or something like it - I copied by hand, tried to be as accurate as possible):

Boot from (hd0,0) ext3dc1c3da9-a9cd-4d6a-80df-3ffba9d899d

Starting up...

Loading, please wait

kinit: No resume image, doing normal boot...
*Checking battery state...
[OK]
Ubuntu 9.04 chestna-desktop tty1

After that, the screen doesn't respond to anything I do, except when I go to Ctrl+Alt+F2 (or F3-F6)
Then I am prompted for my login and password.
After I do that, the screen does not respond to anything I do - except for when I press enter, and it does that "chestna@chestna-desktop" thing.

Is there no other option besides backing up everything and reinstalling Ubuntu from scratch?

Use the live cd and change it back to KDM.

If that doesn't fix it, then we can rule out other problems.

az,

Thanks for the speedy reply! I did change it back to "kdm" and the computer rebooted beautifully.

Now I've just got to:

1. Find out what else it was I did (like tweaking to speed up the computer) that jacked this machine up, and/or

2. Find a "safe" way to change to gdm.

2. Find a "safe" way to change to gdm.

Open a terminal (in KDE, Konsole) and give the command

sudo dpkg-reconfigure gdm You will need to restart X for changes to take effect.
