13.04 is no longer supported. Is this still a problem on 12.04/14.04/14.10?

I would press "Ctrl+Alt" and the computer would restart (with a message that "Ctrl+Alt+Del" was pressed). Then I noticed that the problem is with the left Ctrl key - in the terminal, when I pressed just the left Ctrl key it would output sometimes e.g. "5~;5~" other times it would keep printing "-----------" or "vvvvvvvvvvvvvvvvvv". The output in the terminal without X was different and also a bit erratic. The same for the left Alt key - in the terminal it would output e.g. "A;3~A;3~A;3~A;3~A;3~A;3~A;". It happens randomly - sometimes the Ctrl and Alt keys work as they should, sometimes not. I haven't noticed any pattern to it. I doubt it is a hardware problem because before the upgrade I had no problem with the keyboard whatsoever. But anyway, to be sure I disconnected and reconnected my laptop's (Thinkpad T420) keyboard. It made no difference. $ xprop -root | grep XKB _XKB_RULES_NAMES_BACKUP(STRING) = "evdev", "pc105", "us", "euro", "" _XKB_RULES_NAMES(STRING) = "evdev", "pc105", "us,cz,de", "euro,qwerty,", "grp:s hift_caps_toggle,grp:alt_shift_toggle" $ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd layouts = [us euro,cz qwerty,de] options = [grp grp:shift_caps_toggle,grp grp:alt_shift_toggle] model = xev output for left Ctrl and left Alt: KeyPress event, serial 37, synthetic NO, window 0x3800001, root 0x9b, subw 0x0, time 9639209, (100,-16), root:(102,67), state 0x10, keycode 37 (keysym 0xffe3, Control_L), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 37, synthetic NO, window 0x3800001, root 0x9b, subw 0x0, time 9639376, (100,-16), root:(102,67), state 0x14, keycode 37 (keysym 0xffe3, Control_L), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False KeyPress event, serial 37, synthetic NO, window 0x3800001, root 0x9b, subw 0x0, time 9641112, (100,-16), root:(102,67), state 0x10, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 37, synthetic NO, window 0x3800001, root 0x9b, subw 0x0, time 9641239, (100,-16), root:(102,67), state 0x18, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: unity 7.0.0daily13.06.19~13.04-0ubuntu1 ProcVersionSignature: Ubuntu 3.8.0-31.46-generic 3.8.13.8 Uname: Linux 3.8.0-31-generic x86_64 ApportVersion: 2.9.2-0ubuntu8.4 Architecture: amd64 CompizPlugins: [core,bailer,detection,composite,opengl,decor,compiztoolbox,snap,resize,mousepoll,wall,gnomecompat,vpswitch,grid,regex,imgpng,place,move,animation,expo,session,workarounds,ezoom,staticswitcher,fade,scale,unityshell] Date: Tue Oct 8 12:03:05 2013 InstallationDate: Installed on 2011-06-06 (854 days ago) InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Release amd64 (20110427.1) MarkForUpload: True SourcePackage: unity UpgradeStatus: Upgraded to raring on 2013-10-01 (6 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1236799/+subscriptions -- Mailing list: https://launchpad.net/~dx-packages Post to : dx-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~dx-packages More help : https://help.launchpad.net/ListHelp
