I'm running Ubuntu 9.04 on an ASUS laptop. A couple of days ago my /home partition filled up. Then, while cleaning it out, I lost power. When I restarted the computer I found I couldn't log in -- any login attempt just got me a black screen, a quick flicker, and then threw me back to the login screen. It's not a credentials problem, as I don't get the "login failed" message.

I can open a console (Ctrl-Alt-F2) and log in to any of my user accounts from there; just not from the GUI login.

I have the following session types: Default, GNOME, GNOME/Openbox, KDE, KDE/Openbox, Openbox Session, Secure Remote Connection, Window maker, and Failsafe. Doesn't matter which one I choose (except for SRC, which gives me "Login failed"), I get the same loop.

I thought maybe some config file got messed up, but since it doesn't appear to be Gnome or KDE specific, I'm not sure where to look.

Help, please.

Hello,

Since you are able to get to the command line. Give this a try:

please enter:

Code:

PROMPT#>sudo dpkg-reconfigure xserver-xorg

Keep the default answers, if you do not know what to answer. Pay attention to your screen settings, this is probably what makes your graphical session not available. Once you're done, enter:

Code:

PROMPT#>sudo reboot

Hopefully you session will return.

Also did you get the files cleaned from your home folder before power loss? If not make sure you clean them. This could have a harmful affect on starting.

Good Luck,

Jaysunn

Make sure you have enough space in both /tmp and /home. Run df to get idea

Code:

df -H

Remove unwanted files or move 'em to pen drive.

Code:

PROMPT#>sudo dpkg-reconfigure xserver-xorg

Did this, and it rewrote xorg.conf.

I didn't see anything in the above about screen settings. Here's the resulting xorg.conf:

Code:

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

After rebooting, same problem.

I've cleaned out some of my /home partition. df -H now reports root (/) 9.2gb free and /home 4.9gb free. I've also cleaned out /tmp. But I can't find any .Trash directories, either in my home directory or off root.

BTW, I've several user accounts on the machine; all exhibit the same behavior.

Have you enabled compiz? This may be causing your issue. Please try this:

Code:

PROMPT>sudo chmod a-x /usr/bin/compiz

Worth a try.

Also post your xorg.log file if that does not work:

/var/log/Xorg.0.log
