I have upgraded to Ubuntu 14.04. Everything is fine so far. But every time I press left control button, my DVD drive ejects. It does not happen with right control button. I have searched for answers but could not find anything. Any help is much appreciated.

  • Can you run gsettings list-recursively 2> /dev/null | grep --ignore-case ctrl and paste the output to http://paste.ubuntu.com/ – Fabby Dec 11 '14 at 23:00
  • I have pasted the list. http://paste.ubuntu.com/9489857/ – user2574723 Dec 12 '14 at 14:41
  • So it's not in Gnome that the key was re-defined... :-( Can you do a xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p' and see whether the output gives you 9 Escape 3 times if you press it 3 times? – Fabby Dec 12 '14 at 17:59
  • 36 Return 9 Escape 9 Escape 9 Escape This is the output I got. – user2574723 Dec 13 '14 at 14:04
  • Sorry, I was working on 2 keyboard problems at the same time and the last output was not for you... (copy-paste error from my side: the other user had an escape-key problem, you should have pressed the [Ctrl] key). From the first output, I can see that the problem is deeper then gnome/unity, so could you post the output for [Ctrl] for xev? – Fabby Dec 14 '14 at 10:14
  • 37 Control_L 37 Control_L 37 Control_L This is the output. Hey I just wanted to thank you for looking at my issue. – user2574723 Dec 14 '14 at 12:48
  • yeah, but you're not going to like what I'm saying next: it's correct in Gnome, correct in X, so I have no clue where it was re-defined... This happens not only in one particular application, does it??? – Fabby Dec 14 '14 at 12:55
  • No matter what application I am running. The moment I hit left control button, the drive ejects. – user2574723 Dec 14 '14 at 17:25
  • Grasping at straws now: gsettings list-recursively | grep --ignore-case "eject" – Fabby Dec 14 '14 at 19:43
  • org.gnome.settings-daemon.plugins.media-keys eject 'Control_L' org.gnome.settings-daemon.plugins.media-keys eject 'Control_L' org.gnome.desktop.a11y.keyboard bouncekeys-beep-reject false org.gnome.desktop.a11y.keyboard slowkeys-beep-reject false – user2574723 Dec 16 '14 at 04:11
  • In system settings, I reassigned shortcut for the eject. The problem is solved. Thanks though. – user2574723 Dec 16 '14 at 04:18

Final answer: In system settings, reassign the short-cut for the eject to anything not containing Ctrl

  • Please click on the little grey check-mark icon below the "0" and that is the best "Thank you" you can give me as anyone else having this problem can find that as an accepted answer. (and my reputation goes up) ;-) – Fabby Dec 16 '14 at 08:45

I don't have this problem but I may help you at least with a few ideas. First, I have Ubuntu installed on an old Windows laptop and as you may know the SUPER key showed in keyboard shortcuts is Windows key on my laptop. Now you may have a problem that Ubuntu will see your left CTRL as a key combo or a special key,so try to connect a different keyboard to see of it still does that. If yes, the key mapping has been understood wrong by Ubuntu and you will have to search and download a keyboard mapping program, but the preliminary test for this is to put up the (or a) on-screen keyboard and see if clicking the LCTRL will still open your CD-ROM. In the ABSOLUTE worst case re-install Ubuntu. Now I just found out: go to system settings, under Text Entry and in the bottom right corner you should see keyboard settings. Check that out. If nothing indicates the use of LCTRL then do sudo apt-get install gnome-tweak-tool in terminal and from there you HAVE to find it. Thanks for reading!!
