Thread: help I broke KDE!

  1. #1

    Default help I broke KDE!

    Hi I'm in need of help. Unfortunately I think I broke KDE.

    For some unexplained reasons KDE crashed while I was working on my computer. The screen went black and a part from a couple of windows left open everything else was gone: desktop, icons....

    so I used Ctrl+Alt+BKS to log out. when I attempted to restart KDE it didn't work and it kept on sending me back to the login.
    upon rebooting I'm unable to see KDE and I only have a small terminal window (which seems to be in a some sort of graphical mode) and at the command "startx" the system replies that X is already running.
    If I reboot in safe mode, when I give "startx" I get a black screen.

    Any idea on how I could get KDE working again?
    thanks in advance for your help!

    Do you get any error message from that small terminal window?

    What you can do is boot into text mode.
    Login as your own user and run this command:
    Code:
    mv ~/.kde4 ~/.kde4BU
    This will rename your .kde4 folder.
    This folder stores all your KDE settings, so by renaming it KDE will create a new one.

    Once you've done that you can reboot and try to log-in.
    If it doesn't work you can try to make a new user (for test purposes).
    Boot into text mode, run this command:
    Code:
    YaST2
    Select Security and Users->User and Group Management.
    Select Add and fill in the form, press ok and once again.

    After that you can reboot and login as your new user.

    Best of luck!
    Where did I put my coffee cup?
    dir -R /home/* | grep "coffee cup"

    thanks for your quick reply.
    unfortunately it looks like nothing is working.
    the normal user doesn't create a new KDE4 folder and the new test user doesn't even add all necessary folders to the /home folder (Desktop, Documents...).
    I can login with the normal user and from the little CLI I have I can start dolphin and other programs including YaST2. When I try to install programs or to update the software I get a bunch of errors and the message that / is full!!!

    I'm a bit worried...

    If you log into the CLI, and do a "df" without quotes, you'll see that / partition is full. SOmething is filling up your root partition, so the OS cannot use the "temp" folder anymore for all the temporary files. You need more storage for your root parititon. Free up some space.

    ok, I managed to delete some files from temp and I logged in with KDE!!G
    now my next problem. / (10GB) is still almost completely full.
    one of the largest files is /proc/kcore which says is 128TiB !!! can this file be deleted?

    Never delete files from /tmp on a running system. Use Yast-System-Sysconfig Editor for that. Search for "tmp" and set the appropriate value for /tmp to be cleaned at next boot.


    The file /proc/kcore is not a real file. Don't attempt to remove it. It's the same size here


    Ask yourself what you installed, other than the default. These days 10GB is not too much, certainly not if you install some games, have some mysql databases etc.

    /proc files are not real files they are not stored on the disk. They are just reflections of the state of the kernel processes. In Linux all things are files.

    10 gig for root partition is a little low for serious use.

    You can clear the temp files at boot with this setting

    YAST-System-/etc/sysconfig Editor - System-cron-CLEAR_TMP_DIRS_AT_BOOT

    set this to yes

    That's not real. Don't touch that file. Something else is filling up your root partition. Leave /proc directory.

    Please type the following command in a terminal:
    df -hl
    and post the output here.
