Version: 3.0 (using Devel) Installed from: Compiled sources Compiler: gcc version 4.3.1 20080612 (Red Hat 4.3.1-2) (GCC) downloaded from fedora rawhide repository OS: Linux Hi, I'm reporting a bug for the KDE Beta 2. The following is information about my machine and the crash: Qt: 4.4.0 KDE: 4.00.83 (KDE 4.0.83 (KDE 4.1 Beta2) KWin: 3.0 Kernel: 2.6.25.6-55.fc9.x86_64 Laptop: HP Pavilion dv6575us Display: NVIDIA GeForce 8400M GS, driver version 173.14.09 installed with kmod-nvidia (fedora package) OS: Fedora core 9 updated to the latest (except gcc, everything is from normal repo) KDE: - kdelibs Revision: 823913 - kdebase Revision: 823971 - phonon Revision: 823711 - built using GCC 4.3.1 (downloaded rawhide version) in a separate account (installation directory=~/kde). Crash: This crash happens everytime I login into KDE. Login using standard login (preinstalled in fedora, looks like GDM), and when the desktop appears an error message always appears (always SIGSEGV) along with the backtrace.I tried this eight times, some things that happened (no restart after login unless it dies): 1. For the first login after boot, the system seems to load just fine until the crash report shows up. 2. While at the splash screen, a small logo (called system-run after I looked it up) is drawn with a small area of the desktop background. I think it's supposed to be bouncing but it's only drawn once. The panel is also visible in the bottom, but the widgets are mirrored vertically. Then it crashes and restarts. 3. Third time's the charm (really). The small system-run symbol appears again, but this time it's flickering for a few seconds, then the display just dies. The power button is still working though, so I turned it off and tried again. 4. The fourth time went exactly like the first. 5. The fifth time, system-run appears again (I think it shows up when I move the mouse), then it flickers every few seconds. Then it crashes and restart, and initially there's no borders but it soon fixes itself. 6. On the sixth try, the mouse stalls, then the splash screen goes away revealing everything upside down withsome alignment problems and no panel. It occasionally flickers, then goes mostly black before crashing and restarting to a correct desktop. 7. On the seventh try the screen flashes once before going like the first. 8. On the eighth try the desktop appears right, the system-run is bouncing before kwin crashed and restarted. The backtrace looks exactly the same for all the tests, I'll post it soon. Hope this helps, thanks for making KDE!
Created attachment 25583 [details] Backtrace for try no. 6 Here's the backtrace.
Mike may be able to recreate this if the crashes are caused by the same thing as in bug 162046. What nVidia drivers are you using Cipta?
Never mind, 173.14.09.
The crash only happens when using blur for me. I also get some of the same flickering and rendering of parts of the screen upside down and blurred on some logins (not as predictable as this bug). Logging out and then back in normally fixed this problem. I am not using blur at the moment but that backtrace look fairly familiar. I couldn't manage to downgrade below 169.07 because of some changes to the kernel, but I got the same problem with that. Let me know if you need another backtrace and I can get a few to add to this bug report.
Cipta, open ~/.kde4/share/config/kwinrc and look for the line kwin4_effect_blurEnabled=true and change it to: kwin4_effect_blurEnabled=false Do the problems still exist?
no, it doesn't actually. I logged in a few times and it went just fine. So the blur effect in KWin causes this? Because the folder view widget is still blurring the background.
Can anyone on a 64-bit system that doesn't use nVidia reproduce this crash?
Wait- no, the folder view doesn't blur the background anymore, so I think all blur is disabled. Sorry if it causes confusion.
I am using the latest fedora rawhide package now and the bug doesn't appear anymore. So I think this is fixed, and I'm marking this resolved.

Reopening.
I've switched to KDE 4.1.1 and the bug is reproducible there. I've taken new crash report, it considerably differs from the old one so I will attach it in the next message.

Is actual for KDE 4.1.2
I confirm this bug. I am using nvidia restricted drivers 177 on kubuntu amd64 with nvidia gforce 8400 kde 4.1. It is quite serios as when I don't get kwin error msg i need to reboot whole system and pray for error msg to make this work ;] I noticed that the problem occurs when I enable direct rendering in desktop settings - I will try to see if it will work with direct rendering and blur disabled.

Turning blur off or direct rendering off solves the problem. Both of those cannot be enabled together.
I can confirm this behaviour. Blur enabled -> crash. Blur disabled KDE starts up without any crashes. What is the root cause? The nvidia driver or the blur effect or the combination of both or what? thanks and cheers, michael
I've installed nvidia driver 180.06 BETA and everything works fine now with both blur and direct rendering turned on. Try it out. You can also check a new 177.82 stable driver, may be they fixed it too.
