Question

KDE 3.4 "Configure Desktop" stopped working, various settings changed

Asked by: martin

I am running Mandriva 2006 with KDE 3.4
Yesterday I upgraded OpenOffice from 3.0.0 to 3.0.1: I can't think of anything else that I changed.

Today I noticed that various desktop settings have changed: mouse sensitivity, keyboard repeat, Caps Lock no longer acts as Ctrl, and Firefox looks different.

If I right-click on the desktop and select "Configure Desktop", nothing happens but the following lines appear in .xsession-errors:

kcmshell (kdelibs): WARNING: Could not find module 'background'.
kcmshell (kdelibs): WARNING: Could not find module 'desktopbehavior'.
kcmshell (kdelibs): WARNING: Could not find module 'desktop'.
kcmshell (kdelibs): WARNING: Could not find module 'screensaver'.
kcmshell (kdelibs): WARNING: Could not find module 'display'.

Also, lots of menu items have disappeared from the KDE menu
(System, Configuration, KDE)
I tried rebooting to a recent backup of the root partition, but the problem appears there also. I tried restoring the old version of OpenOffice (which is in /opt which is a symlink to /home/opt),
but this didn't help. Restoring $HOME/.kde from a backup also didn't work.

Installing a new version of Linux, or KDE, is not an option for this
machine. I don't mind going back to the old version of OpenOffice
if that turns out to be the problem (since I hardly use it).

I have backups of my home directory: I can't see any differences that would affect this.

Any ideas as to how I can solve this problem?

This workaround may help you diagnose whethet your KDE is broken or not .

While loged as a standard user in KDE session , try to open Run command

( or  if you can open Kterminal or any terminal for that reason) and then type

-one command at time-  this sequence of commands:

kcmshell desktop

kcmshell background

kcmeshell desktopbehavior

kcmshell screensaver

and so on, following the list of KDE modules errors you are getting in .xsession_erors file. 

    If you cannot get KDE modules  running from command prompt go to  next step.

    Login as root to check whether you can get fully functional KDE desktop and X-session.

In case you can, it may be the sign that KDE configuraton for the standard user is currupt,

so you better carefully pick up all personal files from Home directory for user

account whith which you are having difficulties and then remove that user account.

Create new user account and  login with newly creted user credentials.

If you can get fully functional KDE environment , as root copy all files you moved from

deleted user account elsewhere to new user home directory and - enjoy your oldie KDE 3.4.

If that does not help you may want to launch other desktop ( blackbox, ICE , TVWM ) and use Mandrake's software manager to  remove and reinstall  KDE.

nedvis: thanks for your comment, it helps a lot. But I'm not there yet.

I created a new user, martin2 (actually, copied an existing working user and tweaked it a bit). This works OK.

I replaced martin2's .kde and Desktop directories with martin's, and it still worked (except that it wanted to run the startup programs as martin instead of martin2).

I copied some files/directories from martin2 to replace the ones in my directory (which were moved elsewhere). These were:

.gconf .gconfd .gnome2 .gnome2_private .gnupg .gtk-bookmarks .mcop .mdk-folders .qt

martin2 still works and martin still doesn't!

I assume that there must be some other config files that KDE is reading which are in the martin home directory, but not in martin2. But what are they? I have about 450 dotfiles and directories in my home directory!
Which of these are personal files and which are system files???

I tried copying all the dotfile/directories from martin to martin2, but then I couldn't login to martin2: it hung on setting up process communications.

On martin, "kcmshell --list" produces this output:

The following modules are available:
kcmdf         - Shows the disk usage of the mounted devices
kamera        - Configure Kamera
kcmlirc       - Configure your remote controls for use with applications
kwalletconfig - KDE Wallet Configuration
audiocd       - Audiocd IO Slave Configuration

If I su to martin2 in a terminal window and run "kcmshell --list" I get:

Session management error: Could not open network socket
Session management error: Could not open network socket
kbuildsycoca running...
The following modules are available:
kcmaccess        - Improve accessibility for disabled persons
language         - Language, numeric, and time settings for your particular region
keyboard_layout  - Keyboard Layout
keys             - Configuration of keybindings
componentchooser - Choose the default components for various services

... plus dozens more!

Do you know what other config files KDE reads from?

Problem solved, thanks to nedvis' suggestions. Switching to a different user would cause all sorts of problems with remote logins, NSF mounted partitions etc. But I found a way around that! Here's what I did:

(1) Move home directory to a safe place
(2) Copy files from the working user (martin2) to martin and chown. Check that it works.
(3) Move files and directories back to my home directory, leaving behind any config files that I don't recognise as mine.
(4) I found that the symlink from $HOME/bin/java to a recent version of java caused problems: could it be that KDE calls java without a full path name??

 

by: martinPosted on 2009-02-01 at 02:38:51ID: 31541449

I didn't want to change usernames, so I moved my files to a safe place, copied and chownd the files from the working user to my home direcotry, then moved my own files back to my home directory: leaving behind anything suspicious. It turned out that a symlink from $HOME/bin/java to a newer version of Java was part of the problem.
