Version: (using KDE KDE 3.4.1) Installed from: Gentoo Packages Compiler: gcc-3.3.5.20050130-r1 on Gentoo OS: Linux After upgrading from KDE 3.3 to KDE 3.4.1 keyboard stops working from time to time. This happens about once or twice a day without any obvious reason and therefore it is impossible to write any "steps to reproduce". It is impossible to type anything or use keyboard shortcuts etc. when the problem occurs. No error message appears, after restarting KDE the keyboard works correctly again. There is also a discussion about this problem in the Gentoo Forums: http://forums.gentoo.org/viewtopic-t-333750.html
New information about the bug: The keyboard does not really "hang". It behaves as if ctrl+alt were permanently pressed. And one more thing, the problem seems to happen after using a keyboard shortcut such as ctrl+alt+k or ctrl+alt+m. So it seems that the keys are not released after being pressed (my guess).
you didn't happen to click away the warning that you're about to enable sticky keys?
No no, this has probably nothing to do with sticky keys. Here's a short summary of the keyboard and mouse behaviour when the problem occurs: Keyboard: unable to type anything nor to use other keys such as arrows, enter, esc, ... Mouse: behaves as if ctrl+alt were pressed, which means for example: 1. selection of text in console is done in a rectangle, not line after line 2. bookmarks in firefox are opened in new tab instead of current tab 3. mouse wheel does not work
I also noticed that the num-lock and caps-lock keys get jammed. When I press either of them, the LEDs on my keyboard don't toggle. Only logging out of KDE fixes the problem.
I've also noticed the same problem from time to time - but generally when using konsole. I can be typing a command and it will not accept input any more. If I use the mouse to open another session, you can then type again but then it will freeze up after a short period. Only once have I had a full lock (ie unable to type anything). Currently suffering the situation in konsole but am typing this...
I've noticed the same issue starting today. gentoo/kde 3.4, no real optimization settings. Some of my symptoms : Started out fine, but if I switch my kvm (IOGear usb 4port) by using the ctrl-shift-alt-num buttons, sometimes my keyboard would stop typing, my mouse would only drag/drop open windows, and the mouse wheel would not work. I noticed that if I pressed the num-lock button I could type. I also noticed on the kde bug site it mentioned sticky keys, so I checked that out under the KDE control panel, and it was enabled. I disabled that (Regional & Accessibility ->Accesssiblity->Keyboard. Both of my "Use Sticky Keys" and the subchoice "Lock Sticky Keys" was enabled". I disabled both of them, and tada. I can turn off the num lock and everything is fine.
Just thought that it may be worth mentioning that this problem is still ongoing in KDE 3.5.1.
Same here this is happening more and more. IBM Thinkpad, MS Wireless KBD.Thought it was VMWARE but turns out it is also in KDE. I have to leave KDE and start it again. Then all is fine for awhile. Then Bam happens again. No log, No Dmesg, No X messages. Weird.
It's still going on in 3.5.2. When will it end?
I can reproduce this bug with KDE 3.5.1, KDE 3.5.2 and KDE 3.5.3 More info here: https://bugs.gentoo.org/show_bug.cgi?id=129793
I'm having the same problem on KDE 3.5.4 on (K)Ubuntu Dapper. 2.6.15-26-amd64-k8
As said here: http://forums.gentoo.org/viewtopic-p-3545011.html This may be related to the Accessibility options: 'Use Sticky Keys' and 'Lock Sticky Keys' but I am not sure it helps since I don't use the sticky keys but still have this bug...
The Use Sticky Keys makes no difference.

I'm experiencing random keyboard lockups on my Acer TravelMate 240. I can't reproduce them, but they happen about 2 times a day. Here is the link to the ArchLinux forum, when more people are admiting to experience them: http://bbs.archlinux.org/viewtopic.php?id=30430
This bug bugs me on two Kubuntu feisty (KDE 3.5.6) installations Happens randomly, not necessarily related to any keyboard input at all. Complete freeze of keyboard (no 'hanging key' behaviour). Mouse functions as normal. I can do a logout, and the new session doesn't have the problem. One install is on Intel Core Duo (SMP workstation), the other on Centrino (laptop). Very similar Kubuntu installs. Happens under Xvnc as well.
addition: The funny thing is: I can still use ctrl, shift or alt keys to modify mouse actions! E.g. I can shift-click to multiselect. However no 'isolated' keyboard events seems to be happening.

Finally: i cannot use Ctrl+Alt+Fx to switch vt's, but Ctrl+Alt+Backspace (kill X) still works. Obviously, that doesn't help much when the problematic session is a Xvnc session that I really do not want to kill (I have to re-authenticate my running Citrix connection and I don't have access to the SecurID key :_))
Seth Heeren: This is probably not the same bug. IIRC I was unable to use Ctrl+Alt+Backspace and hangs is always triggered by something. Holding Shift or F1 usually did the job.
KDE 3.5.7, Debian unstable Keyboard locks up about twice per week. Mouse remains working. Can "Switch User" -> "Start New Seesion" to get a working session. Switching back to the old session has a locked keyboard. <ctrl><alt><F[1-8]> does not work in the broken session. While reading bug 74070, the broken session locked requiring a password. I wanted to test moving a konsole as that works for some people. I should have tried pasting my password as that has let me get results from a konsole in the broken session before (I played with setterm and found nothing wrong). Instead I tried <ctrl><alt><Backspace> as that never worked before, but this time it did kill the X-server. The new X-server worked.
i dare to claim that these all are more or less related x server issues and out of kde's control.
Confirm that strange behaviour with kde 3.5.8, kubuntu, on hp tc4200 tablet. After several hours working, keyboard freezes. I wasn't able to find any correlations with other evnts. I have noticed that keyboard does not really hangs, but input gets heavily hampered. Nothing is displayed on kconsole, while typing keys, the usual rate, yet the long sequence of same characters suddenly appears after 4-5 seconds one key has been kept pressed.

I suggest to those suffering from this bug to enable the "show keyboard status" (name translated from Hebrew, but it should be similar) applet in their panel. You could then see the status of the Keyboard metakeys. I use sticky keys due to a disability and I enable this applet to let me know when a key is activated.
This bug started affecting me shortly after updating fron 3.5.9 to 3.5.10. I cannot confirm that it is a KDE issue and not something else, but as a sticky keys user with the "show keyboard status" applet enabled, I can confirm that the system does NOT think that the modifier keys are pressed.
Have the problem here too. Debian unstable 2.6.26-1-686. KDE 3.5.10 After restarting the session it works (with no X restart). So I am pretty sure its a KDE thing.
