Kubuntu V8.10 - Display problem that is not related to X.


So, I admit, I'm a terrible newb and I tried to play with some things before I fully grasped what it was doing.

Here are the facts:

I installed Kubuntu V8.10 on my HP lap-top, side by side with my Windows XP, everything was working semi-fine, except I had "noises" on the display, similar to a bad grounding. It resolved itself down the line, and it is not anymore an issue, but the problem is THAT I TRIED TO FIX THE Noise. And to do that, I went to fiddle in the display control where I did many (probably bad) things. The worstest being that I activated built-in graphic effects.

And as you can guess, it didn't work even a little tad as I would have expected.

Now, the screen is black, I see the pointer and it moves allright, but the desktop is gone. Everything is working fine cause I can access the Command line, I can shut down and I hear the lil music, but I can't see squat.


Those are the things I tried to no avail:

Boot in recovery mode - XFIX - didn't work
Reconfig xserver xorg - didn't work.

The problem isn't in the system, it's in its user settings.

If the worst happens, as the install is pretty fresh, I'm ready to delete and reinstall... if only I knew how...

Every help is VERY appreciated.

Hi Turbomammoth,

Welcome to LQ.org. I can't say exactly which files you have to delete, but I will give you some clues of what to look at (not a Kubuntu user myself). When I need to reset a Ubuntu desktop, I login as usually, and at the command line (if you can't access the command line because your screen is black, press CTRL + ALT + F1), I type this:

rm -rf .gnome .gnome2 .gconf .gconfd .metacity

This will only work for Ubuntu, not Kubuntu. Still, check which files are related to KDE (by typing ls -asl. Anything with a .kde is a sure thing to remove) and remove it.

Side note #1: You will loose your custom settings by doing so (eg: wallpaper and themes will all be reset)

Side note #2: In the worst case scenario, you can remove all your hidden files from you /home folder. Not the best way to do it, but still much better than a reinstall

cd ~
rm -rf .*


should do it.

Best of luck!

Thanks for your help Mega X Man.

However, a reinstall it was.

A tip I can now suggest:
