Ubuntu – In Ubuntu 17.10 key combinations like Ctrl + Shift + Alt + … don’t work

shortcut-keys

I upgraded Ubuntu to 17.10 and found out that alt key has strange behavior.
If I press Alt+Space, for example, I can see the menu of the active window, but If I press more complicated combination like Ctrl+Shift+Alt+some_letter, it doesn't react. In Ubuntu 17.04 it worked.

The only way of solving this problem I know is to use gnome-tweak-tool. In this gnome-tweak-tool, I can swap key Win (Super) with key Alt. In this case everything works great, but… I would like key Win to be key Win and key Alt to be key Alt. So, may be there is a good solution for this problem?

There's an simple workaround here:

In case you don't need to switch between keyboard layouts, you can get some shortcuts working again if you use the "Tweaks" tool for Gnome.

sudo apt install gnome-tweak-tool

Then

  1. Open "Tweaks"
  2. Select the tab "Keyboard & Mouse"
  3. Click "Additional Layout Options"
  4. Disable entries in the "Switching to another layout" dialog

In my case this gave me back the "ALT + SHIFT" combinations which are essential in the Eclipse IDE for refactoring.

It works beautifully!
