I cannot enable desktop effects on my PC with recently installed KDE4. The checkbox is greyed out and the message says: "Desktop effects are unavailable for the reason:" and the reason is empty. I've tried to remove ~/.kde4, create new user, but with new start I always get kwin segfaults. Here is the gdb output from KDE4 dialog. Application: KWin (kwin), signal: Segmentation fault #0 0xffffe424 in __kernel_vsyscall () #1 0xb768d876 in nanosleep () from /lib/libc.so.6 #2 0xb768d694 in sleep () from /lib/libc.so.6 #3 0xb748f65e in ??

I also get segfaults of some applications like glxgears or games-action/violetland but such game like games-fps/nexuiz works with good fps.
I got the same problems. I'm running ~amd64, KDE 4.6.4 on a nvidia card. I'm shure that after upgrading to KDE 4.6.4, i rebooted the system and everything worked fine. In the following days i updated nvidia-drivers (from 270.41.19 to 275.09.07), mesa (from 7.10.2-r1 to 7.10.3) and libdrm (from 2.4.25 to 2.4.26). Afterwards the desktop effects in kde didn't work, kwin and glxgears segfaulted. So I tried every combination of nvidia-drivers, mesa and libdrm. I deleted ~/.kde4/ and rebooted before each try. Combinations with =nvidia-drivers-275.09.07 don't work. When using the old nvidia-drivers-270.41.19 with a ~/.kde4/ which was used since the updates, desktop settings didn't work, too.
Step by step I copied my old ~/.kde4/ files to the new user. The desktop effects with =nvidia-drivers-270.41.06 do work with kwinrc: [Compositing] ... OpenGLIsUnsafe=false ... but do not work with kwinrc: [Compositing] ... OpenGLIsUnsafe=true ... When updating nvidia-drivers to version 275.09.07 and logging in to kde, kwinrc gets modified. In the compositing section OpenGLIsUnsafe is set to true and and Enabled is set to false.
I have the same problem.
I had same problem , and solved it now. I searched any info and find this article. https://bbs.archlinux.org/viewtopic.php?pid=962143#p962143 In my case, just same this. It seems that KDE desktop effects need exec permission at /tmp. I recentry changed description about /tmp in /etc/fstab. none /tmp tmpfs nodev,nosuid,noexec 0 0 Since then, KDE stop desktop effects (but I had no sense). So,I change description again. none /tmp tmpfs nodev,nosuid 0 0 cut "noexec" and restart. open systemsettings and reconfigure DesktopEffects, all come back again.
Seems that nvidia driver indeed requires exec mount option for /tmp. I had no problem with KDE4 effects and noexec set up on a laptop with Intel card. Thank you for that tip.
The noexec-tmp workaround works for me, too. So this bug seems to be the same as #350336
