I just found out the keyboard is affected too: When the mouse acts weird in some way and I open the window-menu via Alt-F3 the menu appears, but I cannot select anything in it, neither with the mouse nor with the keyboard, not even ESC works to close it. So at least part of this bug is related to the window-manager, right? I confirm the behaviour on my system. I am using Gentoo Linux with kde 4.6.0 and qt 4.7.1 with xorg-server 1.9.3.902. It seems that the focus is wrong. Sometimes the window below the current active window is receiving the mouse events. The keyboard events are handled by the active window. Sometimes all Windows are untouched and the mouse events "fall throug" to the desktop. i.e. scrolling in firefox results in changing the desktop (wich is the action for scrolling on the desktop) This happens randomly. Mainly after opening a new window or application. i have noticed that kded4 daemon is also randomly generating 100% cpu. don't know if this is related to each other. kded4 can be only stopped with -9. I'm seeing the same behavior. I'm running Kubuntu 10.10. I'm using a Logitech wireless mouse and Nvidia proprietary drivers. This just started a couple of days ago, so it is something that has just been pushed to kubuntu via automatic updates. When it started, the Input Method Switcher showed up in my Settings menu but reported than zenity was not installed. Installing zenity allowed im-switcher to work, but made no difference in the mouse event handling. All movement events work. button and wheel events within the window with focus work button events in other windows are ignored. xev reports all the expected events including button events in blurred windows. Sometimes right mouse button events will kick something loose so the next left button event will get processed. Cursors mostly change as expected. Occasionally top reports xorg consuming 100% of a very powerful cpu for several seconds just to do trivial window operations, like change focus. Exact same hardware was working prior to recent, past few days, kubuntu automatic upgrade. Also I had to enable legacy USB support sometime within the past week. Never had to do that before. May have happened at the same time as the mouse button issue. I can get around with alt-tab, but a lot of stuff is difficult to accomplish. For example once the screen saver blanks the screen no events seem to get processed so it is impossible to un-blank the screen. For me this is a serious bug and if it isn't resolved very soon, at least with a work around, I'm going to have to do something really drastic to get a working system back. I'm running KDE 4.5.1. I have an Intel i7 920, 6GB memory. Keyboard focus seems to follow alt-tab pretty well, but the ability to recognise mouse button events does not. If I click the right mouse button in the window that is recognising mouse button events then I can left click on a window and it will start recognising mouse button events, but not (or not necessarily) key events. At one point I noticed some weirdness with the cursor. It was showing the hand, not the arrow or I-beam as expected in FF. When I pointed to a tool bar button in FF the cursor started swapping back and forth between the arrow and the hand (I think it was very fast so very hard to tell exactly what it was doing). Once I get keyboard and mouse focus within a window I can use that window ok. Moving between windows is hard. Waking from the screen saver is impossible. I'm now using OpenSUSE 11.4 with KDE 4.6.1 and NOUVEAU-graphics-driver. Bug is still alive. I bought a new wired mouse (Razer DeathAdder ooooooh!) and it works fine. Seems my Logitech wireless mouse is not supported somehow. It used to work. This bug is still in kde 4.6.1 with intel graphics and synaptic touchpad or logitech mouse. I dont think it is related to the mouse type, because i can reproduce the same behaviour with no mouse attached. Why is this bug still unconfirmed? this bug is very annoying .. i have to restart (re-login) kde every few hours to fix it. I'm also experiencing this problem, but it's not KDE's. Actually, it seem Xorg is responsible. For instance, I tried with Xfce and the bug was still there. Then I've found this thread (https://bugs.launchpad.net/xorg-driver-synaptics/+bug/375905) in which several people describes the same problem with different desktops. For me i have found an error related to synaptics touchpad driver that causes the problem. If i disable the touchpad, the error disapears. It is reportet at freedesktop: https://bugs.freedesktop.org/show_bug.cgi?id=26213 (see Comment 13) I am experiencing this bug after upgrading to Kubuntu 12.10 which uses KDE 4.9.3. With the same hardware, I never had this problem before. Has a fix really been found? I find it odd that I never had this bug before, but now have it on updated software, especially considering the age of this report. The bug has been reported here, on Launchpad and on Freedesktop. Has the source of the problem really been found? Killing Kwin, Plasma-desktop or synaptiks did not fix the problem, so I'm guessing those are not the source of the problem. https://bugs.launchpad.net/ubuntu/+bug/375905 https://bugs.freedesktop.org/show_bug.cgi?id=26213 This is no KDE-bug. It is reported to occur on other desktops too. Have a look at the above mentioned bug report on freedesktop.org. *** Bug 325152 has been marked as a duplicate of this bug. *** |
