It looks like a plasmoid just destroyed my KDM:

I was furiously playing around with a few plasmoids, when I pulled one up really big - I don't know anymore which one it was, it had something to do with application starting and it consisted of two icons of my favourites. Anyway, I pulled it up really big to see how big it goes, when suddenly some part of KDM crashes: Menu Bar disappeared and all open windows stuck in place. Then I somewhat overreacted and forced a reboot from a text console.

Now, I get a blacked out screen a second after login and return back there seconds after. The X-Server seems not to be affected. I moved the .kde/ folder, which didn't help.
Any suggestions what to try next? Maybe I could try to locate that one plasmoid and kick it out, if I find the corresponding config-file(s)...

Thanks for any suggestions!

are you sure ~/.kde is where your KDE4 files are and not ~/.kde4 ? this varies by distribution, which distribution?

If the problem is plasma related then erasing/moving/renaming the plasma files in ~/[.kde|.kde4]/share/config/ should fix it.

if you create a new user and log in as it do you have the same problem?
useradd <username>
passwd <username>

I'm sure. My distro is Kubuntu 10.10

It doesn't seem to be plasma-related anymord.

with useradd it didn't work, but with adduser I can get into KDE.



I had a look at .xsession-errors, and it had only 3 lines:

Code: Select all

Xsession started for $USERNAME at $DATE
<unknown program name>(1537)/: Communication problem with "konsole", it brobably crashed.
Error message was: "org.freedesktop.DBus.Error.ServiceUnknown" : " "The name or g.kde.konsole was not provided by any .service files" "

So, apparently it seems to be a problem with my DBus-config, or with the proprietary nVidia driver. I edited the xorg.conf yesterday to fix the screen backlight, and now the OpenGL-Compositing has massive performance problems and flickering display.

I'm not even sure xorg.conf is still required, I think if it exists it will be used but not required see https://wiki.ubuntu.com/X/Config https://wiki.ubuntu.com/X/Config

do you have a backup of the xorg.conf ? it would be xorg.backup


that error I don't think is relevant to your issue, I thinks it due to the crash of konsole

fyi - in openSuse it is useradd, though I do have a man entry for adduser

Yes, it is obsolete. But I needed it to fix a bug in the nVidia driver. But since it is obsolete, there wasn't one before. However, if I rename it now, X11 will mess up completely.

You mean I should fix konsole, and then it should work again?

No, I don't think konsole is your problem, but I could be wrong

If you rename xorg.conf and reinstall your drivers, assuming you use a package, won't the package give you a new xorg.conf? if you compile the drivers then at the end Nvidia will ask if it should create the file or use the existing.

If your problem is the 260 series drivers on a 32bit machine why not go back and use the 256 series?

This could be cache corruption. Remove /var/tmp/kdecache-$USER/
Also, in case your graphics card has been left in an inconsistent state due to the sudden exit of X with KWin compositing running, please reboot your system.
