[SOLVED] Could not start ksmserver

[lewisforlife]

I have Mageia 2. I rebooted my computer today, and when I logged in to KDE I got this message:

Code: Select all

could not start ksmserver check your installation


After the message I am taken back to the login. I tried moving "~/.kde4" to "~/.kd4-old", and am still getting the same issue. I noticed that some files/directories in my home folder were owned by root instead of my user, so I chowned them all to my user. That did not fix the issue. Do you have any idea would the problem could be and how to fix it?

Thanks.

Sometimes I have to remove one or more of other configs to get back in. Try deleting .Xauthority, .xinitrc, .kderc and maybe even .ICEauthority. Moving the .config folder has helped me a few times as well.

I tried your suggestions but the problem isn't fixed. Does anyone have else have suggestions, or should I try removing KDE and re-installing, what is the best way to do that without breaking my system?

You should try making a new user and logging into that before you start uninstalling/reinstalling lots of stuff.

I forgot to say that I already tried creating a new user and logging in, same message.

I just tried uninstalling and reinstalling kde, here is how I did it.

Code: Select all

urpme kdebase4-common
urpmi task-kde4


After the above, I am still having the same issue. Is there anything else that I can try, I really don't want to reload Mageia.

Check your ~/.xsession-errors file. Maybe it has better info why it's failing.

Not much that looks strange, but these two lines:

Code: Select all

Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory

(notification-daemon:3893): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width > 0' failed


Interestingly enough, I tired to run "kate" from LXDE, and it crashes, this is what showed up in .xsession-errors. I am guessing this is related to my KDE issues:

Code: Select all

QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
Cannot mix incompatible Qt library (version 0x40804) with this library (version 0x40801)
KCrash: Application 'kate' crashing...
KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi from kdeinit


What can I do to fix this QT issue? Maybe that will solve my problem.

I checked my version of QT:

Code: Select all

$ rpm -qa | grep lib64qt

As you can see, some are 4-4.8.4 and some are 4-4.8.1 What should I run to fix this?

Looks like there is a bug report here: https://bugs.mageia.org/show_bug.cgi?id=7233

How can I downgrade the QT components that were some how misteriously updated?

That bug report is no real bug, it was caused by the user himself by only doing partial updates.

Please show the output of

Code: Select all

urpmq --list-media active

and

Code: Select all

urpmi --auto-update --test

I just did a system update, and KDE is working now. I guess maybe I did (inadvertently) what the user did in the bug report above, and updated some components of QT without updating the others. Thanks.
