Ubuntu 14.10, Unity, running Windows under KVM. Pressing Ctrl+Altimmediately causes the focused window to maximise vertically (no other keys pressed).

Pressing them again causes the window to toggles between that and maximise in both dimensions. A double click in the title bar maximises (if not already so), and another double click restores the window to its original dimensions.

I have found no binding for simply Ctrl+Alt in Settings→Keyboard→Shortcuts. I also tried CompizConfig settings manager, found no references to Ctrl+Alt

The output of

gsettings list-recursively | grep --ignore-case ctrl | grep --ignore-case alt

can be found here.

  • Start the command find ~ -type f -maxdepth 2 -print0 -iname '.*'| xargs -0 grep -rIP 'Alt_(L|R)' to check your configuration files and add the output into your question as an edit. After that give me a ping with @A.B. in the comments.

Go to settings > keyboard > shortcut tab and create a new custom shortcut using these values:

Name: [What ever you want] Command: false Shortcut: Ctrl+Alt

  • @A.B. It's the only way, and it worth it. Sep 3, 2015 at 7:53
  • The only way is, to find the configuration for the shortcut.

  • @A.B. dude, trust me. there is no command registered with <control>+<alt> that I can find in my system. I searched all shortcuts in compiz. no luck in gsettings list-recursively | grep --ignore-case ctrl | grep --ignore-case alt either. Sep 3, 2015 at 8:05
  • What do you think, how many ways there are to define shortcuts. You'd be amazed.
