Bug#490186: kwin starts eating all keypresses sometimes because of the keyboard shortcuts popup
kwin suffers of a nasty bug that is triggered by the "keyboard shortcuts"
popup. In KDE's Control Center
-> Regional & Accessibility
-> Keyboard Shortcuts
-> Shortcut Sequences
-> Desktop Switching
I have set shortcuts for "Switch to Desktop 1..20" to Win+Tab,1 (1-5, q-t, a-g,
z-b). So first row of keys (1-5) jumps to desktops 1-5, second (q-t) to
desktops 6-10 and so on.
When Win+Tab is pressed, KDE pops up a window at top left corner showing the
available combinations. The title is "Win+Tab,..." and contains a list of the
commands as well as bound keys ("Switch to Desktop 1 1"). Sometimes this
window is closed without the shortcut sequence being completed, which seems to
trigger the bug.
After the bug is triggered, no keyboard input will go to any applications.
Ctrl-Alt-F1 seems to work still though, and mouse does work normally - you can
still change focus of windows etc. Only cure to this I have figured is to kill
kicker and kwin from another X and restart them (DISPLAY=:0 kwin &).
I can't point out the exact version when this was introduced, but it has been
around for a long time.
