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!

are you able to ssh into the machine or anything?

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?

Did you make any changes, upgrades....
Try

Code:

CTRL_ALT_Fx

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

I've been using it for 2 years and I still feel like a newbie haha
Yeah I mean like if you can use putty to connect to the command line interface of the machine

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:

My /home directory is mounted from /dev/sda3 to /media.
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
