I upgraded to Ubuntu 17.10 and wanted to boot with the unity environment, but when I did, I noticed that the keyboard shortcuts like Ctrl+Alt+T for the terminal were not working(only when I boot in unity).

How can I fix that?

    Experiencing this also, I think it's a generalisation of this bug report, so I've left a comment there. bugs.launchpad.net/ubuntu/+source/unity/+bug/1727842

    I'm having the same problem, don't know any solution yet, but doing this: rm -rf ~/.compiz ~/.config ~/.gconf ~/.gnome* ~/.kde solves the problem temporary for me

  • It's working temporary, but it's better than nothing. Thanks a lot !

    @AramilRey Deleting .config/ will also remove config files for non-related applications, this is a very bad advice!

    Yes, try removing some of those one at a time and eventually you will know where the problem is

This is probably related: Super+L to lock screen not working after upgrade to Ubuntu 17.10

The comments on the bug linked there suggest to switch from LightDM to GDM3 until the bug is fixed.

Run sudo apt-get install gdm, and then your password when prompted, or run sudo dpkg-reconfigure gdm. (Taken from here)


As already mentioned in the comments by Aramil Rey, removing the following configuration files seemed to fix the problem:

  • ~/.compiz
  • ~/.gconf
  • ~/.gnome*
  • ~/.kde

And in my case it was a permanent solution and not a temporarily one. For example this can be done by:

mkdir ~/backupFixSO972940
mv ~/.compiz ~/.gconf ~/.gnome* ~/.kde ~/backupFixSO972940

If this does not work, you can also add ~/.config to the list, but be careful as this folder also contains a lot of application related configuration files, thus I advice to make a backup (mv) instead of deleting (rm) all folders directly like from the original solution.
