After upgrading to Ubuntu 18.04, Shortcut Keys don't work

Question

April 28, 2018 I upgraded to Ubuntu 18.04 and everything worked fine. Now, I don't know why I can't get into Nautilus. When I click the Files icon in the dock it starts to load but nothing launches.

I also can't get into the terminal (neither with Ctrl+Alt+T nor with the terminal icon). I don't know if the two problems are related, but they started to happen at the same time.

Edit 1: Rolled up from answer that should be in question, the Nautilus problem was (partially) solved:

I managed to open nautilus from Konsole and now it seems to work fine (I can open it through the dock). However, when I close the Konsole, it fails again.

About the "Shortcut Keys don't work" part.. I had a simmilar issue after upgrading to Ubuntu 18.04 : - Ctrl+Alt+T didn't work - lock screen ( Ctrl+Alt+L ) didn't work - media keys didn't work

Here is what worked for me:

• I installed "compizconfig-settings-manager"
• I opened "General" -> "Commands" and activated the check box on the left "activate commands" and then clicked "Back"

At this point the shortcuts started to work again.

Hope this helps somebody.

My trick to solve it:

1. Install konsole (KDE Terminal) with

   sudo apt install konsole
   

2. In

   Settings -> Devices -> Keyboard

   click "Terminal" and change the its shortcut (for one you won't be using).

3. Scroll to the bottom and press + to add a new shortcut. Write konsole in Command and choose Ctrl+Alt+T as shortcut (choose whatever name you want).

I had the same problem. It's an annoying bug.

Solution 3

I found the Screen lock shortcut changed to Super+L (Windows +L) in 18.04, or at least the default changed for my machine from Ctrl+Alt+L to Super+L.

This isn't all bad as I'm used to locking my work machine (Windohs) with Super+L.

Ubuntu 18.04 probably has the keyboard shortcut set to disabled. Furthermore, there is no "Applications" menu option so these steps below work without third-party installations.

• Go to Settings -> Devices -> Keyboard, then scroll to "Navigation Section."
• Click "Hide all normal windows" which is probably set to "disabled."
• Enter your new keyboard shortcut, which I set to CTRL+Alt+D.

Voila! Instant desktop!

Check your hotkeys in dconf. I have this problem with CTRL+SHIFT+E, It's trying to load emoji language things for me (IBUS related) so I will go ahead and delete that.

The answer is available here and it works just fine: youtube.com/watch?v=8xVWL-5ery4

The shortcut I'm asking about is set by default and it already appears in the hotkey list. That is not the answer.

It is strange because I think that Compiz does not work with Gnome? But I will try

Yes it works for me. Even, if I have compiz-sm installed shortcuts doesn't work. During installation some configuration files were, probably, overridden and to fix that you need open csm → General → Commands deactivate it and activate one more time. Now it works

only this worked for me. Ubuntu 18.04, After setting shortcut for launching terminal finally Ctrl+Alt+T opens terminal now, and Ctrl+T opens new tabs in webbrowser and in nautilus.
