Lost Login Screen on Ubuntu 10.04


Hi there!
I've got a problem on my Ubuntu 10.04. The login screen disapeared, and all that remains is the default background. I mean, the computer turns on normally, but when it gets to the screen where there should be the users names to login there's only the background. Is it possible to reconfigure that anyway?
Thanks in advance!

Hi rjo98!
I'm not quite sure if I know what you mean, I'm new in the Linux world. By "ssh into the machine" you mean if I can access the machina via one of the terminals (tty), text-mode?
Best regards

Did you make any changes, upgrades....
Try
Code:
CTRL_ALT_Fx
login
Code:
sudo /etc/init.d/gdm restart
If this doesn't work
Code:
sudo /etc/init.d/gdm stop
Code:
startx
Take a look in the logfiles to see if there are errors.
If this doesn't work
Code:
sudo dpkg-reconfigure -phigh xserver-xorg
Kind regards

Does Alt-F2 open a place to run a command? If it does, try some of the commands listed above like startx or gdm -restart or gdm -reset.

Alt-F2 only works when you are logged in in the GUI.

Kind regards

Yeah, I was afraid of that but thought it as worth mentioning.

I've come with another problem now.
My PC is partitioned as the following:
-first partition: mounted as /
-second partition: mounted as /boot
-third partition: mount as /home
-and fourth and last partition: swap mounted
I formatted the first two and installed Ubuntu 9.10, and mounted the partitions the same way. The problem is that the third partition, where I have my personal files (/home) was encrypted when I had Ubuntu 10.04 installed some time ago. Now I can't access it (or don't know how to do it). I read some explanation on how to use the ecryptfs command,but I couldn't make it. I wasn't able to mount the encrypted directory. Can you help me?
Best regards

Hi there,

Get to the login screen (Or as close as you can- to the default background etc.) and hit ctrl+alt+f2

This should hopefully give you a terminal- login as usual and then do

Code:
sudo su -
to get to a root shell. At this point you can try repo's suggestions, restarting gdm and so on. Let us know how you get on with this and we can go from there.

As for the encrypted partition; could you give us the output of /etc/fstab and perhaps /etc/mtab?

The login screen is no longer a problem (altough I'll take notes on the tips above for any problem of the kind in the future), now that I have formatted the PC. As for the outputs from mtab and fstab, here they come respectively:

Hope that helps.

Hi,

What happens when you do try to mount /dev/sda3 ? mtab suggests it is mounted- you can't view the data?

How about
Code:
fdisk -l

I got through the problem.
I reinstalled the system keeping the same mount point from /home.
When I first logged in, the system asked me for the key to decrypt my /home folder.
I may say I felt a lot better when I saw that it worked.
Thank you all anyway, for the attention and effort.
May you have a nice week!
Best regards
darthpinguim
