Since recently that worked well (or rather so-so, but thats unrelated). Some time ago I started getting hangs when Kwin resized one window to make room for another (e.g. when opening a second non-foating window on a virtual desktop). Details of the hang: - cpu-usage of Xorg goes to 100% - the mouse still moves (although jittery) - applications freeze, I cannot click anything, keyboard is dead (not switching to a VT possible) - ssh login is possible and computer can be restarted, but Xorg cannot be killed manually, not even with SIGKILL - there is nothing in dmesg, the only thing in Xorg.0.log is: [mi] EQ overflowing. The server is probably stuck in an infinite loop. I am using xorg-7.5.1 installed from packages, with a ATI r480 card and xf86-video-ati-6.14.0_1 . Desktop Effects are turned *off*. KDE is 4.6.1, although I don't think KDE is the problem here, it just triggers some driver issue. I will gladly provide any further info. Thanks for your help! >How-To-Repeat: Set KWin to tiling mode (Systemsettings -> Window Behaviour -> Window Behaviour -> Advanced -> [X] Enable Tiling). Maybe also set "Columns Layout" and "Raise/Lower all floating windows". Open any application, make sure the window is not floating (right-click on titlebar). Open a sceond application and also make sure its not floating and not maximized. -> hang >Fix: >Release-Note: >Audit-Trail: >Unformatted:
