Can't get past login-screen

[Spherical]

I had no issues what-so-ever today to (auto) log on to my XBMC box. All was perfectly fine.
Until a disk-scan.

Now, I have to enter my password, but if I do, I just hit back to the login-screen.
This goes for all GUI's, KDE, Gnome, XBMC, XFCE, doesn't matter what I choose, I just get thrown back to the login after a short black screen.

The xorg error-log does not show anything worth mentioning (1 warning for the driver "void" not existing)

Anyone has any clue?

I'm running Kubuntu 8.10, because it works for my touchscreen, combined with XBMC.
Not much special to say...

On another note... while on touchscreens.
Anyone have any experience with touchscreen (evdev/evtouch) under 9.10?
I'd like to upgrade, but can't be sure it works (although this current installation fails too huh)

If someone can assure me and tell me how to get my touchscreen working, I'm gonna reinstall, but I prefer not too

It sounds like X is crashing.

Sometimes the gdm/kdm log will contain error messages that Xorg.0.log doesn't catch. So when using kdm, take a look at /var/log/kdm.log.

I think gdm has its own subdirectory in /var/ with a bunch of files.

This is all kdm.log reports:

That Error is my touchscreen, it's been there forever, never caused any problems.

[Zorael]

Curious.

If you create a new user (from a recovery session or similar), does it happen for him as well?

[Spherical]

Yes, exactly the same happens.
It's really odd.

I'm thinking I'll just do a reinstall... I'm afraid there's not enough data to repair this issue.

[kio_http]

Try this


sudo dpkg --reconfigure xserver-xorg

If that fails then


sudo apt-get purge xserver-xorg
then

sudo apt-get install xserver-xorg

[Spherical]

Tried that already.

Sadly, it only screwed my touchscreen-configuration, but nothing else.

I've resorted to the last option:
Format
Install Kubuntu 9.10

It's working all now, I'm just hoping it stays that way ;)

[Spherical]

Ok, all is working the way I want it in Kubuntu 9.10

I've very "cleanly" installed my touchscreen and dualscreen setup the way I have had it working since Kubuntu 7.04, but who cares, it works.

This, sadly, makes the issue I started this thread with not yet solved. Although I hope nobody will encounter something like this
