Resolution issue causing login screen loop

Question

My ubuntu (version 10.10 I think) is stuck in loop at the login screen. Looks like it could be a resolution issue. - I have an nvidia graphics card (gs 8400). I previously had it connected to a 19" monitor however disconnected mid session and since then the issue has persisted. I tried uninstalling the gdm package and reinstalling and running an apt-get update however the login loop still there.

Is there another way I can reset the resolution settings to fix this looping issue?

I can get into the desktop by going through the rescue mode and using startx but its not a solution.

Solution 1

You can edit /etc/X11/xorg.conf by hand

Or you can use nvidia xconfig if you have the proprietary driver sudo nvidia-xconfig

Or sudo dpkg-reconfigure -phigh xserver-xorg

Solution 2

• Switch to the text console Ctrl-Alt-F1
• Login with your username / password
• Check for errors, write them down word for word. Did you enter your home directory?
• Check the output for ls -l /home. Does it say drwx at the start of the line, notice especially the w?
• Check for nearly full filesystems df -h
• Type exit
• Switch to the graphics console Ctrl-Alt-F7
• If you had any errors on the text console, add them to your question.

Solution 3

What I did wrong was to try to use xstart, in error. When using xstart .Xauthority is created in user directory. I've had problems with this on other systems, deleting the file(s) solved the problem for me.

sudo dpkg-reconfigure -phigh xserver-xorg will reset back to default.

Where does the 32768 come from? Does sudo dpkg --configure -a; sudo apt-get update; sudo apt-get-upgrade get you any further?

My user id (via id command) comes out to 1000. Root comes out to 0.

Thanks for your contribution and welcome to AU. Please focus on how the problem is solved. I think formatting your answer (paragragphs) should be enough.
