Alt+Tab and Super+Tab not working after upgrade from 17.04 to 17.10

Question

I just upgraded to Ubuntu Gnome 17.10 after 17.04 went out of support.

After the reboot finalizing the upgrade the Alt+Tab and Alt+Super stopped working.

However, the "Switch Application Windows" Hotkey keeps working, and, if I keep the switcher open by holding down Alt, I can then switch between Applications using Tab.

I already tried resetting those settings and setting the shortcuts using the terminal:

gsettings set org.gnome.desktop.wm.keybindings switch-applications "[]"
gsettings set org.gnome.desktop.wm.keybindings switch-applications-backward "[]"
gsettings set org.gnome.desktop.wm.keybindings switch-windows "['<Alt>Tab', '<Super>Tab']"
gsettings set org.gnome.desktop.wm.keybindings switch-windows-backward  "['<Alt><Shift>Tab', '<Super><Shift>Tab']"

I also switched these around a bit to experiment but couldn't get it to work.

But as of now this is pretty annoying.

How can I fix this?

Answer 1

Update:

You can try reloading Gnome via ALT-F2, pressing R and then Enter.

Thanks to Rob Hendricks for this hint.

Original Answer

Interestingly, after issuing the above commands, a reboot fixed it, when reloading the desktop environment didn't.

So for anyone encountering this, set your preferred settings using:

gsettings set org.gnome.desktop.wm.keybindings switch-applications "[]"
gsettings set org.gnome.desktop.wm.keybindings switch-applications-backward "[]"
gsettings set org.gnome.desktop.wm.keybindings switch-windows "['<Alt>Tab', '<Super>Tab']"
gsettings set org.gnome.desktop.wm.keybindings switch-windows-backward  "['<Alt><Shift>Tab', '<Super><Shift>Tab']"

And reboot.

Answer 2

The above answer by FatalMerlin worked great. You can also do an ‘alt-f2’ followed by ‘r’ and enter to restart gnome without the reboot...
