KDE4: Hints, Bugs, Fixes

A running list of stuff about the KDE4 desktop -- typed in from little slips of paper I have laying around on my desk:

  • To make the desktop run faster, compile qt-copy without the -debug option

  • My computer has a Radeon video card and the X server apparently uses an ATI driver. This driver seems have to problem with compositing. If you see "screen turds" and other strange graphics effects, especially with the menus and icons, try disabling compositing... which seems to be enabled by default on my system.
    Do this by adding these lines to the end of xorg.conf and reboot:
    Section "Extensions"
        Option      "Composite"     "disable"
    EndSection
    

    Oh, disabling compositing should also fix 'ksnapshot'.

  • If you start a KDE4 application from a command line, you might notice a bunch of messages that indicate this app can't talk to knotify. That's because 'knotify4' probably isn't running. You can remedy this by running 'knotify4' from a command line. Also, I hacked my 'startkde' to run 'knotify4' for me when I login. I plan to commit this to the official 'startkde' tomorrow, unless someone objects on the k-c-d mailing list.

  • BUG: 'kwalletmanager' gives me this message "kwalletmanager(4467) KWalletManager::KWalletManager: kded not running?". Then it displays a closed wallet in the systray. dfaure said he will fix this on Monday -- if I remind him. :)

  • BUG: 'kmail' isn't remembering shortcuts between restarts.

  • BUGLET: hmmm.. seems that instances of 'kded4' continue running after I quit my KDE4 session.

  • BUG: There is no nepomuk D-Bus service file. We need one if we expect nepomukdaemon to start as needed; for example, from 'dolphin'.

  • BUG: Alt-F2 doesn't work. I expect that key sequence to start 'krunner'.

  • WTH? KOrganizer is unbearably slow. I see no reason for this and KOrganizer ran great for me under a KDE3 desktop. This problem needs some serious research. Does KOrganizer work ok for anyone?

>> BUG: Alt-F2 doesn't work. I expect that key sequence to start 'krunner'.

I think you can get it to work by deleting a file in your ~/.kde. Sadly I can't remember the filename or the exact location.

What exactly is slow about KOrganizer? I didn't notice this on my machine. What kind of setup are you using, remote calendars, specific resources?

I'm using the Birthdays and Standard Calendar resources.

If I'm in agenda view and click on another week in the date navigator it takes about 10 secs (wall clock) for that selected week to appear.

if I'm in month view and click forward 1 month in the date navigator it takes about 20 secs (wall clock) for the next month to appear.

I see a bunch of messages (~100) like the following in the Konsole from where I started korganizer:
korganizer(26091) KOMonthView::changeIncidenceDisplayAdded: Visiting GetDateVisitor failed.

It took me a few days to relearn the habit but swapping Alt-F2 for Alt-F1 gives the same end result. Yes, the desktop search gives (instant?) results for installed executables.
