NVIDIA / nouveau thread branch [was Re: Fedora 12 QA retrospective - feedback needed]

[Orcan Ogetbil]

I have an issue with the nvidia driver in KDE. Certain actions, such as
- clicking on the K-menu
- clicking on the clock
- using an auto hiding panel
- ...
freezes KDE for 10 exact seconds. Afterwards things continue as if
nothing happened. I also saw this reported in nvnews.net under the
evdev thread. I didn't have time to locate the source of problem,
although it's most possibly evdev. Please let me know if there is a
solution or workaround.

kmod-nvidia-2.6.31.5-127.fc12.x86_64-190.42-1.fc12.4.x86_64

I have such error messages in Xorg.0.log:

(**) Option "xkb_rules" "evdev"
(**) Option "xkb_model" "evdev"
(**) Option "xkb_layout" "us"
[mi] EQ overflowing. The server is probably stuck in an infinite loop.
