KDE 4.4.5 crashes (kwin?) at random points

Hi there
I have a very annoying problem. When I login to KDE from KDM, i can browse arround for about 30 seconds, and suddently KDE crashes and I'm thrown back to the KDM prompt. It's always crashing no matter which programs I'm using, but it seems that it crashes more frequently when I'm using a web browser, eg. firefox with the opensuse kde integration patch. I've tried to rename .kde4, .kde and .mozilla folders in ~/, That action delays the crash, but it still happens.

I haven't had this problem before i issued a big system upgrade yesterday, where it seemed the whole KDE desktop, linux kernel, xorg + drivers got upgraded.
So right now i have the following configuration (which may cause some problems, I don't know);

local/xorg-server 1.8.1.902-1 (xorg)
    X.Org X servers
local/xorg-server-utils 7.5-4 (xorg)
    X.Org utilities required by xorg-server
local/xf86-video-ati 6.13.0-1 (xorg-video-drivers)
    X.org ati video driver
local/xf86-input-evdev 2.4.0-1 (xorg-input-drivers)
    X.org evdev input driver
local/kdelibs 4.4.5-1
    KDE Core Libraries
local/kdebase-plasma 4.4.5-1 (kde kdebase)
    Display the contents of folders (User´s home folder as default)
local/gtk-qt-engine-svn 5-1
    Plugin that allows GTK applications to use Qt4/KDE4 widget styles. SVN Version

My graphics card: 02:00.0 VGA compatible controller: ATI Technologies Inc RV790 [Radeon HD 4800 Series]

I've checked my .xsession-errors when it crashes, but i do not understand that log file at all. However, i have pasted it here: http://pastebin.com/bSvmmWpG

Then I found out, that disabling desktop effects in kwinrc solves the problem, but I don't think it's very funny to live without desktop effects

I hope some of you guys can help me (and others, if they should have the same problem).
Thanks in advice

Try removing gtk-qt-engine-svn. That always gave me problems.

Re: KDE 4.4.5 crashes (kwin?) at random points

I've tried that now, and i doesn't solves the problem. Thankyou for the answer anyway.
I don't know if the problem is reproduceable, but it happens when i'm doing one of the following:

- Having desktop effects disabled and enabling them through system settings
- Having desktop effects enabled and writing in the adress bar in firefox with opensuse patch causing the menu to drop down
- Just browsing arround, having chromium and konqueror open

When running KDE in failsafe mode (or just having desktop effects disabled) everything seems to run fine including firefox with the opensuse patch.

So.. it seems having something to do with those desktop-effects, which is in "open-gl" mode. Maybe it's only a graphics card/driver specific issue? Are there other ati users with a recent system who're facing the same problem. Or maybe Nvidia or Intel users?

it might be a kms-related problem. enable kms and see if that helps.

Looking at your log file it seems that the problem is moonlight (errors start at line 634). Try disabling or removing it and see if that fixes it.

Re: KDE 4.4.5 crashes (kwin?) at random points

Same thing here, crashes after about 30 seconds after loading any browser.

Edit: Actually my problem is quite similar to this:
http://bugs.archlinux.org/task/19971

Edit: Never mind, it seems I couldn't get KMS running because my Arch26-CK kernel. KMS is now working and has fixed the problem, as anti-destin suggested.

After enabling KMS it works here too. Great suggestion anti-destin
Dekstop effects hasn't worked with KMS in the past, but now it does, so that's just great.

Re: KDE 4.4.5 crashes (kwin?) at random points

this problem has been popping up a lot recently, and enabling kms seems to resolve it in most cases. i'm glad it worked here.
