Hello, I also have this problem, but I don't have lineakd installed. The problem is like this: When I press ALT+TAB, kwin presents me the list of programs, but I can switch to another window correctly. The window list stays on the screen an nothing happens. If I now press TAB once more, focus is changed to the selected window. See bug 255216 for more info: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=255216
Regards, Cesar.
