KDE will not launch

I am fairly new to linux. My first distro was kubuntu, and am now trying Fedora with KDE. I was annoyed that the open windows were not shown on the task bar. I tried adjusting all sorts of things, and finally figured out that all I had to do was add a certain widget. I had no idea that this is what I was looking for, since kubuntu already does that by default. But in the process of figuring this out, I caused KDE to crash. The next time booted with Fedora, KDE would not launch. So I logged into a virtual terminal and ran startx. I got the following errors:
Code:
error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory
startkde: could not start kdeinit4. Check your installation.
Can anyone tell me how to fix this problem? Thank you.

Re: KDE will not launch

Remove or rename the .kde/config directory in your home directory. You will lose the configuration for some apps but it should solve the problem.
Alternatively create a new user and see if they can start kde. If so it is a config issue, if not then something has been deleted that you need but that is probably unlikely.

I wanted to make sure it's clear that the correctly installed KDE4 in Fedora does show open windows in the taskbar. At least mine sure does and I didn't need to install anything extra by hand. Apparently it was something that went wrong in your install.

Re: KDE will not launch

Ok, first of all I don't seem to have .kde/config. When I list the contents of .kde, I get
Code:
Autostart Cache-DellFedora Share Socket-DellFedora tmp-DellFedora
DellFedora is what I named my computer. I tried adding a new user and get the same thing. On searching the internet further for a solution I found the suggestion to use
Code:
prelink -f /usr/bin/kdeinit4
When I tried to do this, it said it could not find one of the dependencies. I suppose it is possible that I have a faulty install. Certainly reinstalling would fix the problem, but I would like to see if there is another way. As I said before I am new to linux, so I want to use this as a learning experience. Thanks for the help.

Re: KDE will not launch

Sorry my error should be .kde/share/config

Also Marko is correct the taskbar does show the open windows as standard. Although it defaults to only showing windows on the current desktop.

Re: KDE will not launch

removing .kde/share/config did not do the trick. Are there any other suggestions?

Looks to me like you're missing that library file libQtGui.so,
so install the qt-devel package that it's in:

yum install qt-devel

Re: KDE will not launch

Did you try another user as I suggested earlier?

Yes I have tried a different user. Could it be something with kdeinit4 itself?

Re: KDE will not launch

Hi leigh123linux,
When I tried your suggestion, I was not able to complete the reinstall. I was told
Code:
Installed package 1:qt-x11-4.6.20.fc13.i686 (from updates) not available.
Nothing to do.
So what would you suggest now?

Re: KDE will not launch

Give a while then try again. There is a newer version and I'm guessing your mirror was in the process of resyncing when you tried the installation.
