** Description changed: Ubuntu 14.04 xserver-xorg: 1:7.7+1ubuntu8.1 I don't know how to trigger this bug, but I have seen it now more than ten times. "Suddenly" = I can't figure pattern how this triggers. Sometimes it happens when computer just idles 'stops working normally' = tab-key alone doesn't do anything. -- When tab-key is working normally, xev reports: KeyPress event, serial 37, synthetic NO, window 0x2400001, - root 0x290, subw 0x0, time 2088488, (164,-6), root:(1515,797), - state 0x0, keycode 23 (keysym 0xff09, Tab), same_screen YES, - XLookupString gives 1 bytes: (09) " " - XmbLookupString gives 1 bytes: (09) " " - XFilterEvent returns: False + root 0x290, subw 0x0, time 2088488, (164,-6), root:(1515,797), + state 0x0, keycode 23 (keysym 0xff09, Tab), same_screen YES, + XLookupString gives 1 bytes: (09) " " + XmbLookupString gives 1 bytes: (09) " " + XFilterEvent returns: False KeyRelease event, serial 37, synthetic NO, window 0x2400001, - root 0x290, subw 0x0, time 2088509, (164,-6), root:(1515,797), - state 0x0, keycode 23 (keysym 0xff09, Tab), same_screen YES, - XLookupString gives 1 bytes: (09) " " - XFilterEvent returns: False + root 0x290, subw 0x0, time 2088509, (164,-6), root:(1515,797), + state 0x0, keycode 23 (keysym 0xff09, Tab), same_screen YES, + XLookupString gives 1 bytes: (09) " " + XFilterEvent returns: False -- When this bug triggers, xev reports (when tab-key pressed and released): FocusOut event, serial 37, synthetic NO, window 0x5600001, - mode NotifyGrab, detail NotifyAncestor + mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 37, synthetic NO, window 0x5600001, - mode NotifyUngrab, detail NotifyAncestor + mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 37, synthetic NO, window 0x0, - keys: 4294967184 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 - 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 + keys: 4294967184 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 + 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 -- When this bug triggers, xev reports (when holding CTRL and tab-key pressed and released): KeyPress event, serial 37, synthetic NO, window 0x5600001, - root 0x290, subw 0x0, time 261350060, (172,-19), root:(1523,784), - state 0x0, keycode 37 (keysym 0xffe3, Control_L), same_screen YES, - XLookupString gives 0 bytes: - XmbLookupString gives 0 bytes: - XFilterEvent returns: False + root 0x290, subw 0x0, time 261350060, (172,-19), root:(1523,784), + state 0x0, keycode 37 (keysym 0xffe3, Control_L), same_screen YES, + XLookupString gives 0 bytes: + XmbLookupString gives 0 bytes: + XFilterEvent returns: False KeyPress event, serial 37, synthetic NO, window 0x5600001, - root 0x290, subw 0x0, time 261350228, (172,-19), root:(1523,784), - state 0x4, keycode 23 (keysym 0xff09, Tab), same_screen YES, - XLookupString gives 1 bytes: (09) " " - XmbLookupString gives 1 bytes: (09) " " - XFilterEvent returns: False + root 0x290, subw 0x0, time 261350228, (172,-19), root:(1523,784), + state 0x4, keycode 23 (keysym 0xff09, Tab), same_screen YES, + XLookupString gives 1 bytes: (09) " " + XmbLookupString gives 1 bytes: (09) " " + XFilterEvent returns: False KeyRelease event, serial 37, synthetic NO, window 0x5600001, - root 0x290, subw 0x0, time 261350276, (172,-19), root:(1523,784), - state 0x4, keycode 23 (keysym 0xff09, Tab), same_screen YES, - XLookupString gives 1 bytes: (09) " " - XFilterEvent returns: False + root 0x290, subw 0x0, time 261350276, (172,-19), root:(1523,784), + state 0x4, keycode 23 (keysym 0xff09, Tab), same_screen YES, + XLookupString gives 1 bytes: (09) " " + XFilterEvent returns: False KeyRelease event, serial 37, synthetic NO, window 0x5600001, - root 0x290, subw 0x0, time 261350572, (172,-19), root:(1523,784), - state 0x4, keycode 37 (keysym 0xffe3, Control_L), same_screen YES, - XLookupString gives 0 bytes: - XFilterEvent returns: False + root 0x290, subw 0x0, time 261350572, (172,-19), root:(1523,784), + state 0x4, keycode 37 (keysym 0xffe3, Control_L), same_screen YES, + XLookupString gives 0 bytes: + XFilterEvent returns: False --- And behaviour is like xev reports: tab pressed alone doesn't do anything, but with any modifier it works as expected: alt+tab = change window shift+tab = previous element (e.g. fields in browser) ctrl+tab = change tab (e.g. in firefox) ----- I have ~/.Xmodmap and it contains line: keycode 23 = Tab ISO_Left_Tab Tab ISO_Left_Tab Tab ISO_Left_Tab Running xmodmap ~/.Xmodmap will not fix. --- Attaching new usb-keyboard doesn't help. --- Reboot helps. - + Restarting xorg helps. --- Changing to virtual terminal -> tab is working. But after returning to xorg, tab is still broken.
