I am running openSUSE 11.1 with KDE 4.1.87 (just upgraded today). I am not sure if this is related to this release, but today my desktop is really acting choppy. I have KWin effects enabled, as I always have, but they are much less smooth compared to yesterday (4.1.86). Also plasma seems to lock up occasionally. The RSSNow widget is very chopy when it slides feed content. All in all, it feels like I'm running on my old Dell Dimension. I am using Intel integrated graphics, but this is a quad core machine and it's always handled effects well (Rated 5 on Vistas Experience, and handles Areo nicely).

I have heard rumors on the openSUSE sites that KDE4 has been not behaving nicely on Intel Integrated graphics. Does anyone else get this same behavior?

For intel cards, switch to XAA rendering for smoother performance.
To do that, at konsole type:

Code: Select all

sudo kate /etc/X11/xorg.conf

And find the following:

Code: Select all

Section "Device"
        Identifier      "Configured Video Device"
EndSection


and add this one line:

Code: Select all

Section "Device"
        Identifier      "Configured Video Device"
        Option          "AccelMethod" "XAA"
EndSection


PS: Even id the "Identifier" value isnt same, try looking for section "Device".
After adding the code, save it and exit Kate. Now reboot your computer.

Why reboot? We are not in Windows It is enough to restart X - basically should be enough to logout and login again.

Thanks! Seems a lot better now!

Isn't XAA the old acceleration model? Shouldn't the newer EXA be used? If XAA truly is the correct settings for KDE4, please add it to Userbase so other people can find the necessary information.

That is interesting, considering that for older radeon cards EXA is much better than XAA instead...

EXA is a bit broken right now. EXA though is definitely better.

Yes! Ctrl + Alt + Bkspace is maybe what I should've said.

That is not the way either. Either you go by "init 3" and then back to "init 5" or, in some distros, just stop the display manager through the proper script (in arch might be /etc/rc.d/kdm)

Have fun!

Well this is the safest way which will work in all distros nevertheless in most cases Ctrl+Alt+Delete is set as a shortcut for X restart.

I don't want to seem a know-it-all but Ctrl+Alt+Delete is not a shorcut for X to restart, is a shortcut to *kill* it and it is usually set to automatically restart. There's a difference

Without acrimony,

Yes, you're right I meant Ctrl+Alt+Backspace. Thanks for correcting me.

I also tried this to get rid of the "choppiness" on my Intel i915 based Dell box. Unfortunately it made things even worse as I only got a black screen after restarting X. I could only use Magic SysRQ to get the machine to reboot.

Other than that I have put everything from the Composite Howto on Techbase into my xorg.conf, but it doesn't help.

Is there anything else I can do?

Thanks...
