Description Nico Kruber 2009-07-05 16:42:03 UTC

Version:            (using KDE 4.2.90)
Installed from:    SuSE RPMs

Sometimes my KWin gets into the state as if ALT was pressed, i.e. windows move when clicking somewhere and dragging them) and I cannot exit that state.
The only thing that keeps working is the task bar, but I cannot enter anything via keyboard. The keyboard is blocked in all the other windows, too - only things that do work is CTRL+ALT+F*, CTRL+ALT*BACKSPACE and similar shortcuts.
Logging out and back in again restores everything to normal.

I cannot really give a description on how to re-create that behaviour, buuuut this is what resulted in that state last time: I was hovering over an .mp4 file in Dolphin (it usually takes a very long time for dolphin to generate the tooltip (with no preview or thumbnail or similar) although a 5MB file limit for previews is set and video previews are not checked). While waiting, I hit F2 and changed to another window. This is when I could only move it instead of using that window :(

This bug has been annoying me for quite a while but as it is not easy to reproduce it, I haven't filed a bug-report yet - although I'm not quite sure whether that bug already existed in KDE 4.2

actually I'm now using 4.2.95 (4.3 RC1) but this version wasn't available in the drop-down list.

Did you check if sticky keys are enabled?  Go to System Settings -> Accessibility and make sure sticky keys are disabled.

Comment 3 Nico Kruber 2009-07-05 19:52:40 UTC

Sticky keys are disabled

Comment 4 Raju 2009-07-07 01:28:52 UTC

if u understand that , the keys are working as there is "alt" is pressed. i.e. 
"k" is working as "alt + k" .....etc etc....

then press "alt"....this will stop the combinating those keys with "alt"

Comment 5 Nico Kruber 2009-07-07 23:25:45 UTC

I cannot undo this by just pressing ALT (unfortunately) - this is the first thing, I tried ;)

Although, I did not notice any app responding to any key press in the past, I'll check whether the shortcuts work, e.g. whether using F4 results in ALT+F4, next time that happens...

Comment 6 Nico Kruber 2009-07-16 12:16:33 UTC

ok, this happened again just now, and although windows are moved as if ALT was pressed continuously, shortcuts do not work, i.e. pressing F4 does not result in a window getting closed.
