Version: 4.2.2 (using KDE 4.2.2) Installed from: Unlisted Binary Package When working with KDE4.2.2 sometimes after login or after some action (after blank screensaver, opening dolphin, kmail, firefox, ..., and switching apps) something steals mouse focus and disables left mouse button click. The only way to repair that problem is to log out. Killing applications does not work (see attached ps auxw) Even disabled panels, no plasmoids. Very hard to reproduce. Restarting with kwin --replace didn't the job (actually, it worked one for me). Disabling desktop effects, restarting plasma - does not helps. Tried on clean profile too. Running xwininfo says that it can't grab mouse focus. Sometimes it starts, but I'm unable to left-click (I can right click, and it shows me info about window). I'm using PLD-Linux.org, i686, nvidia binary display driver, xorg-xserver-server-1.6.0-7.i686 USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 2252 1256 ?

I can confirm the problem. This seems to be caused by xorg anyway: I found some bug reports for xorg in ubuntu launchpad. They committed a patch to xorg-server that corrected the problem for a lot of people... here, the problem remains. So it's connected with xorg, or with nvidia drivers. E
Emanuele, could You post a link to that launchpad page with xorg patch?
I cannot find it at the moment, sorry Piotr! Anyway the patch is already commited in xorg server 1.6... The problem seems related to Xinerama: here, I tried to disable both twinview and xinerama, and the problem is gone. Do you use Xinerama/Twinview too?
No xinerama/twinview, and actually using xorg 1.6.1... Thanks anyway.
Problem occoured again, even without Xinerama/TwinView. It's really weird... If someone without nvidia drivers has the same problem, please let us know. If not, it's probably a problem with the nvidia binary... I'll try with the beta drivers...
I have this very bug since last week or so. I think it's not kde related because it started to happen suddenly when using KDE 4.3.2 and i used it for a while. Moreover I think I upgraded some X packages at that time. I don't have twinview or xinerama but I do have nvidia binary drivers. Here's my system: Arch Linux xorg-server 1.7.1 KDE 4.3.3 nvidia 190.42
@Iago López Galeiras: I was also experiencing this bug with the last ArchLinux updates and KDE from trunk (4.4.x). I think I have managed to workaround the issue by disabling the mouse gestures. (check SystemSettings/Input Actions, disable the Gestures option, and restart KDE/PC) I hope it can help you too. Thanks
I've been using metacity today to check if the bug is kwin's fault but it seems not because it happened again. I will try disabling mouse gestures now, although I love it. Thank you Dario Andres :)
I've been using kwin with composition activated and mouse gestures deactivated and the problem is gone. Should't we pass the bug to khotkeys?
The same here. Gestures from khotkeys do nasty things with mouse focus. KDE 4.4b2 (KDEmod on Arch), but I've seen the same bug one or two times using stable 4.3.
Dear Bug Submitter, This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond. Thank you for helping us make KDE software even better for everyone!
Dear Bug Submitter, This is a reminder that this bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? Thank you for helping us make KDE software even better for everyone!
No response; assuming it was fixed since then.
