Screen becomes unreadable after login

[lildoggie]

Hi,

I've got a new installation of 11.04 server. Everything was apparently working just fine, and then the system hung. I rebooted, and everything looked good up to the login screen. After I typed my password, the screen started looking good, and then got all fuzzy and messed up (nothing was readable). The only way I could get anything back was to reboot. (I *am* able to work via ssh at the command line, though).

As the graphics were fine before (using GDM), and since the GUI looks fine at the login screen, I know the system can do it...

I tried to find information on what might be going wrong, and haven't been able to find anything that fixes the issues. I thought there might besomething in my config, so I tried logging into another account on the system that doesn't have any user-level configuration, and got the same result (the machine's main purpose is to be a mail and file server).

So it appears to me that something is happening to the graphics configuration after login when GDM loads.

Any thoughts on what I need to change?

Thanks!

You could try reconfiguring your xorg.conf or just check the x log file.

BTW did you install the proprietary drivers or the oss ones?

Thanks for the reply.

First, no proprietary drivers installed - just the default (which worked fine for a while, and work fine for the login screen).

Strangely (?), I don't have an xorg.conf file -- I thought it should be configured by default, but there's no xorg.conf file in /etc/X11.

I looked at /var/log/Xorg.0.log, and it seemed to correctly identify my ATI Radeon card. I didn't see anything else in that file that seemed to indicate any problem (but then again I don't know what I'm looking for).

Any additional thoughts?

Thanks again!

Hmm...
That's strange . Try creating your own xorg.conf or generate one.

Pus try lxdm to see if it works.If it does then its safe to say that its a gdm related problem.;)

How would I generate one? I tried doing a reconfigure, expecting to need to answer some questions, and it just threw me back to the command prompt without doing anything.

What is the command to install/activate lxdm?

Thanks again!

OK, I was able to log in using the "Classic (no effects)" option, and things are fine...

This is all good, since I don't think I need any effects. However, I'm just curious what could be causing the problems for the other options...

Any ideas?

Thanks!

My guess is that the drivers couldn't handle the load properly and x crashed.
But I guess it doesn't matter anymore.
Glad you are able to solve your problem.

Anyway its good that you were able to solve your problem.

Oh yeah

Its a simple apt-get install lxdm and away.:)
