    Plasma keeps crashing

    For about a week now, Plasma keeps crashing on 9.10 It suddenly crashed for about a week ago, and now it keeps crashing

    I've already tried the trick of moving .plasmarc and .plasma-appletrc to my home folder, but Plasma still keeps crashing.

    What to do about it? I don't want to reinstall...

    Info:
    Kubuntu 9.10 32-bit
    KDE 4.3.3
    Qt 4.6 bèta from Kubuntu Experimental PPA
    Sony Vaio VGN-NW21MF
    4 GB RAM
    500 GB hard disk
    ATI Mobility Radeon 4570HD with official propetiary driver installed
    Intel® Core™ 2 Duo-processor T6600
    Most important laptop specs (this is my main computer, with Kubuntu on it):<br /><br />4096MB RAM (DDR2)<br />500GB Hard Disk<br />ATI Mobility Radeon 4570HD Videocard with 512MB GDDR3 RAM, up to 2280MB VRAM<br />Intel® Core™ 2 Duo-processor T6600<br /><br />OS: Kubuntu 10.10

    Re: Plasma keeps crashing

    I had plasma crash a couple of times and Firefox would slow to a crawl and freeze occasionally. I am also running KDE 4.3.3 because I had thought the newer packages might fix things up, they didn't... I started looking in the proposed repos for possible answers. I ended up installing the updated xorg packages and a couple of the gtk packages. So far things seem to be all right.

    The updated xorg packages got rid of a sluggish shut down problem I was having. Sometimes the system would take a long time to shut down and restart, it was rather random behaviour. The updated xorg packages have taken care of this issue. The updated gtk packages may have been the cure for the sluggish and freezing Firefox problem I was having but I can not be certain that this is what actually fixed it. My thinking on this was that Firefox is gtk based and, what the heck, it was worth trying. Firefox has not slowed down or froze since I updated the xorg and gtk packages so I think it is fixed.

    I was selective with what I used fron the proposed repo because I am using Intel graphics and did not want to break the system if I could help it. Possibly the things I mentioned might apply to your situation. Plasma has not crashed since I applied the updates I mentioned and I hope the problem is resolved. The updared xorg packages might help you because you are using ATI graphics and that might be the underlying cause of the plasma crashes.

          Unfortanatly it didn't help Plasma still keeps crashing. Plus I get the error that Ubuntu is running in low-graphics mode, while it isn't :S

            It has to be something related to the ATI drivers. Sorry my idea did not help....

                Thanks for all the help so far

                Here is the output of the two logs idyllic asked for:

                  Re: Plasma keeps crashing

                  - Xorg.0.log

                  Code:
                  (II) fglrx(0): ***Display: ConnectedDisplayTypes=0x00000002,disabled=0x00000000

(EE) fglrx(0): Unknown EDID version 0
                  Try to reconfig your fglrx, try backup /etc/ati/amdpcsdb, remove it then reboot

                  - .xsession-errors
                  I saw Nautlius and gnome stuff spawning all over the place. Nautilus will spawn a desktop, thus I think plasma-desktop will recrash. Are using a gnome-session to get us a log?

                    Re: Plasma keeps crashing

                    Yes, I give you the log via a GNOME session.

                    How exactly do I reconfigure my fglrx?

                      Re: Plasma keeps crashing

                      1. Backup your /etc/X11/xorg.conf and /etc/ati/amdpcsdb

                      2. Replace your /etc/X11/xorg.conf with this generic fglrx xorg

                      Code:
                      Section "Screen"
    Identifier   "Default Screen"
    DefaultDepth  24
EndSection

Section "Module"
    Load  "glx"
EndSection

Section "Device"
    Identifier   "Default Device"
    Driver "fglrx"
EndSection
                      3. Remove your /etc/ati/amdpcsdb, the reboot and pray.

                        Re: Plasma keeps crashing

                        I tried that, I still get the error of low-graphics mode, but now I not even get past the error. So I'm writing this from my other computer which has openSUSE.

                        What can I do now?

                          Really sorry to hear that. Since you have the back-up, just restore them if you can access your kubuntu box again.

                          Also please pastebin your xorg.conf as well.

                          Also
                          Code:
                          Kernel command line: BOOT_IMAGE=/boot/vmlinuz-2.6.31-15-generic-pae root=UUID=4da54cf9-697a-483d-a6c8-a37eddcf97ac ro splash vga=789 quiet quiet splash
                          @_@ Can you try remove vga=789 quiet splash (1 of them each)

                          It is kind of late here now, I try to get back to you tomorrow morning.
