    Default 11.2: KDE Apps Excruciatingly Slow after upgrade

    Hi! I've just upgraded from 11.1 to 11.2. My KDE apps (Firefox, Yast, Kmail) are now excruciatingly slow - particularly Kmail which is now virtually unusable. Before the upgrade on my 3GB RAM laptop the response was great - so something has broken during the upgrade process. What is interesting is when I open in Failsafe - the speed is fine.

    My thoughts are maybe graphics card acceleration but why would it be ok in failsafe?

    Not really sure where to start looking here. Any help greatly appreciated.

    First, create a new user. If that user's OK, then it's your configuration.

    Get into runlevel 3, then move your original user's .kde4 directory to a backup place

    Code:
    mv ~/.kde4 ~/.kde4.bak
    Then try to recover individual important directories within it (again within runlevel 3), hopefully isolating the problem (or at least getting to a point where you don't mind setting up again).

    Slightly painstaking, but it might well work...

    Thanks for the suggestion. The created second user has the same problems as the first user. It makes me think this could be graphics card hardware acceleration - I'll do a google search see if it sheds some light.

    I am moving forward on this. I have solved why the problem isn't happening in failsafe mode. The boot kernel flags in /boot/grub/menu.lst determine how the kernel is loaded, and without the x11failsafe flag my system runs excruciatingly slow.

    So, the problem lies within x11failsafe. That flag I believe determines whether /etc/X11/xorg.conf or /etc/X11/xorg.conf.install is used when loading X11. So therefore the issue is in the xorg.conf file created during the upgrade process from openSUSE 11.1 and 11.2

    That's my next point of inquiry. If anyone else has encountered this, please feel free to chip in and help me

    Cheers!

    In a terminal window type 'top' and <enter> and see what's eating your CPU cycles.

    On failsafe (i.e. with x11failsafe flag) my CPU is 0.5%

    On normal (i.e without x11failsafe) my CPU is 100%, Xorg is using everything. Which is interesting, because it means the cycles are not being used by the apps (Kmail, Firefox etc) but by Xorg itself.

    Not sure where to go from here.

    Further information - my graphics card is the Intel Mobile 4 Series Express. Perhaps the driver was 'upgraded' during the openSUSE 11.2 development. Unfortunately I've lost my 11.1 xorg.conf file so can't compare what it was like before the upgrade.

    Well it is certainly narrowed down to X somewhere. Try reinstalling
    your display driver.

    Just FYI, there is no xorg.conf in 11.2
    You have to run sax2 to initiate that file, which might be necessary, but I have not had to do so on either of my machines. (see sig)

    I should migrate from my 10.3 KDE machine to my 11.1 KDE 3.5 machine.
    But i am working more overtime than i can really handle and that is
    too much like work.

    I had a very similar problem. After the upgrade from 11.1 to 11.2 Kmail was extremely slow (I have an IMAP account, whether that matters or not I could not test). Other KDE components such as Kwrite seemed not to be affected.

    I did not go through the hassle to create a new user or use the failsafe mode. I found a simple workaround: I uninstalled everything connected to the scim input method. Now Kmail is back to normal. I guess the problem resides within scim or the kmail integration of scim.

    Maybe that helps!
