Another Debian user reported this problem in the Debian Bug Tracker here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=463363 Just start your xserver, turn on MouseKeys, then after 5-15 minutes MouseKeys will stop working (i use sawfish). A friend of mine experiences this too (xfce4, debian sid). Other related quirks: - sometimes a key gets stuck (rare). For example the letter 'a', so the text "aaaaaaaaaaaaaaaaaaaaaaaaaaa...." gets typed into the current application. Sometimes a modifier gets stuck this way, like control or meta. I can bring it out every time by playing any flash game on kongregate.com which uses the keyboard. - sometimes (raaaaare) sticky keys stops working too. That's it, keys arent sticky any more. - after MouseKeys stops working, I can't switch terminals using Control-Alt-F keys. Just doesn't work. Before that I can use that combo as usual. I can help with any testing you need, just contact me. Thanks, Richard
Here is a recent topic on the linux kernel mailing list about the stuck keys issue. http://groups.google.com/group/linux.kernel/browse_thread/thread/f00fb4e0300ec914/41e779c7c37ee373?lnk=raot The best answer may be this: "Now, if X has a need for low-latency for keyboard handling, then the X developers can use mlock to lock the X keyboard service in memory, and make it a real-time (or at least high priority) process too. This should avoid the problem even with extreme swapping and/or high cpu load."

Richard: can you verify this please?
(In reply to comment #3) > Richard: can you verify this please? > Unfortunately Debian only has 2:1.4.99.901-2 (experimental) and 2:1.4.1~git20080131-4 (sid). I have never compiled Xorg for myself, but I'll try and give it a spin on Sunday, I will report back here. Thanks.
I confirm this bug as solved. All the quirks are gone. My xserver-xorg-core version is 2:1.4.1~git20080131-4 (Debian). Thank you.
