When Print screen is pressed in KDE xev outputs these messages: FocusOut event, serial 31, synthetic NO, window 0x1a00001, mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 31, synthetic NO, window 0x1a00001, mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 31, synthetic NO, window 0x0, keys: 2 0 0 0 0 0 0 0 0 0 0 0 0 4294967168 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 KeyRelease event, serial 31, synthetic NO, window 0x1a00001, root 0x65, subw 0x0, time 1671733774, (35,-25), root:(1352,934), state 0x10, keycode 111 (keysym 0xff61, Print), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False So only keyrelease event, no keypress event there. Normal behaviour is (for example when I press 'a' key): KeyPress event, serial 32, synthetic NO, window 0x1a00001, root 0x65, subw 0x0, time 1671779381, (47,-24), root:(1364,935), state 0x10, keycode 38 (keysym 0x61, a), same_screen YES, XLookupString gives 1 bytes: (61) "a" XmbLookupString gives 1 bytes: (61) "a" XFilterEvent returns: False KeyRelease event, serial 32, synthetic NO, window 0x1a00001, root 0x65, subw 0x0, time 1671779452, (47,-24), root:(1364,935), state 0x10, keycode 38 (keysym 0x61, a), same_screen YES, XLookupString gives 1 bytes: (61) "a" XFilterEvent returns: False When KSnapshot is installed, it's executed. Without KSnapshot, nothing happens. Problem is, when evdev driver for Xorg is used - there are different keycodes, 111, which is normally Print Screen, is assigned to the 'up arrow' button. Because these behaviour depends on keycode, when up arrow key is pressed, KSnapshot is executed or nothing happens. I've searched at KDE bugzilla - there I've found, that it's not hardcoded in KDE and it's distro problem. The bug report there is at http://bugs.kde.org/show_bug.cgi?id=125559. Is there a possibility how to disable this or it is a bug?

Discovered, that it's an error in KDE, althought they written, that not. KHotkeys uses keycodes, not keysyms, that's the problem. Marked as invalid.
