I think the following two issues are related:

1) ALT-rightclick, Super-rightclick etc. have no effect on the gnome panel.

2) I cannot set certain shortcuts using System Settings -> Keyboard -> Shortcuts. For example, the ALT key is recognized as "Level3 Shift", and cannot be combined with any other key for a shortcut. The Windows key is recognized as "Multi key" and again cannot be combined with other keys.

I'm using Gnome Classic on Ubuntu 16.04. Gnome Version 3.18

There are two versions of Gnome-Classic Which come from Gnome 3.18 in Ubuntu 16.04. One is using Metacity as the window manager and another uses Compiz, which is the same composition manager used by Unity.

I guess you're using the one which uses compiz, and this gnome-classic doesn't allow you to do Alt-RightClick in the panel so that you can customize it. But there is a workaround. You can quickly switch the window manager to Metacity and then make changes to the panel and then switch back to compiz.

To do so

  • Open a terminal (Alt-Ctrl-T)
  • Type metacity --replace and hit Enter
  • Now do Alt-RightClick on the panel and customize what you want.
  • Now press Alt-F2 to bring the Run dialog
  • Type compiz --replace there and hit Enter

Keyboard Shortcut

As for the keyboard shortcut, I guess you're using wrong Keyboard Layout. Change the layout to En-US by going to Settings -> Text Entry -> Input Sources and Add the English (US) Layout

  • Thanks! Regarding the keyboard layout: my keyboard is indeed a UK English keyboard, and the layout is correctly shown in the Settings. The same keyboard worked fine with Ubuntu 14.04. Aug 15, 2016 at 20:29
  • Glad to help. But the SE way of saying thanks (if the answer is helpful) is voting up the answer :) And accepting it if that solves the problem. I think your second problem is unrelated with this one and hence should be asked in another question separately

The above tip didn't work for me. I tried the metacity --replace and that process hung. And everything except the mouse stopped working: even my current terminal window no longer took text input. Couldn't change window focus. (I had logged in with Gnome classic.) After I logged out and logged back in again, I did a ps ax | grep first for metacity and then for compiz. Neither was running. Alt -right mouse click does nothing for me. Ubuntu 16.04. I had been use flashback, but a recent system update screwed that so that watching a video switched primary/secondary monitors and changed monitor until I ran Settings - which switched them back on startup, but left all firefox tabs un-refreshable except by changing windows. At least GDM basically works.
