As far as I can tell everything still works fine, it just delays the boot process a lot. In X the UI responsiveness randomly goes bad, keyboard especially. At first it'll be fine, then simply using Konsole and typing will begin to slow down. Also, screen output in general seems to freeze until I touch the mouse or keyboard. Even something like listing a directory. It's really weird... It gets so bad that it becomes completely unresponsive, freezing for minutes at a tie. It eventually un-freezes momentarily, long enough to logout and back in at least. I disabled desktop effects but it still had the same problem. I tried Gnome briefly last night before going to sleep and didn't experience this slowdown problem. Anyone else had those same problems or know what I might try? I'm using nvidia-drivers and tried 3 different versions with no success. I have not yet tried downgrading my kernel or KDE installation, but that's next on the list of things to try tonight. FYI last night I upgraded to kernel 2.6.35.5 and everything seems to be working normally, so I guess whatever caused my problems has been solved. I still have long waiting on uevents at boot time, but I guess it's normal and was unrelated, and I usually only boot once every few months so it's not a big deal. :) Thanks, Paul

I downgraded to kernel 2.6.34.3 and everything runs smoothly again. No more hangs or sluggishness. It would seem that something in 2.6.35 series kernels does not like my computer, or something in my computer does not like 2.6.35 series kernels. Based on LKML lurking I guess I'll need to learn how to git bisect the kernel and prepare myself for many reboot cycles. Either that or keep using old kernel and hope my problem is fixed either on purpose or by accident in future kernel releases.

Not sure if this is related (esp. since you have an nvidia card using proprietary drivers) but it may provide some insights to your problem: https://bugzilla.kernel.org/show_bug.cgi?id=16265 Best regards Peter K

I suppose you're running a complete ~arch system, not just some packages? Also, I had a somewhat similar problem with GUI slowness. It was a matter of disabling the Use VSync checkbox in System Settings-Desktop Effects-Advanced tab and enabling the Disable functionality checks box in the same tab. Note that the desktop and all apps will keep being tear-free and VSynced even if making those changes in System Settings. Furthermore, I've set: CheckIsSafe=false in my ~/.kde4/share/config/kwinrc After all that, KDE 4.5.0 runs perfectly for me using gentoo-sources-2.6.35-r1, xorg-server-1.8.99.905, and the following live () packages: media-libs/mesa x11-proto/glproto x11-proto/dri2proto x11-libs/libdrm x11-drivers/xf86-video-ati Using KMS.

I'm using nvidia-drivers, and didn't try the - version of those last few packages but otherwise tried the rest of your suggestion. Tried also upgrading to qt-4.7.0_beta2 but still having the freezing problems. It happens even without desktop effects enabled, just plain 2D mode. So it seems something is just not right... will keep experimenting.
