Ubuntu 17.10 Mouse can't click on Gnome Elements, Keyboard Misbehaving

Asked by Joscha Finger

Yesterday I upgraded from Ubuntu 17.04 to 17.10; it turns out that now I can't click on any elements that are directly GNOME-related: the Dock is dead, and the top panel also doesn't 'see' the mouse, doesn't react to clicks.

The login screen also doesn't react to clicking; the cursor moves just fine.

Inside most windows (Chrome, for instance), clicking is not a problem, and elements I've got lying about on the desktop can be clicked on and work.

The configuration window for the mouse works fine, scrolling and clicking are recognised inside that window, too.

Closing a window is possible only if the app has its own exit dialogue -the usual window operations don't work.

I've tried with both my usual wireless mouse (Logitech M150) and a few wired ones -no difference at all.

As for the keyboard (Logitech K220), inside the login screen it works perfectly, but then the number block 'dies', regardless of whether I press the NumBlock key.

I've got a strong feeling the two problems are related.

echo $XDG_SESSION_TYPE

tells me "x11", so it's definitely not a Wayland issue.

Can anybody help me, please?

 It turns out the window frame buttons of some apps do accept clicks. Chrome does, Chromium does not, neither does LibreOffice. Videos does. Clementine just won't start whatever I do. Home can be opened via keyboard (Superkey), the window's interior works fine, and closing it is not a problem

I tried connecting two different cabled USB mice using an old PS/2 adapter. This did not work: the mice were simply not recognised. A cursor was visible but didn't move with the mouse.

I tried two various suggestions at http://sourcedigit.com/21687-ubuntu-usb-mouse-not-working-ubuntu-touchpad-not-working/ : reinstalling xserver-xorg-input-synaptics and setting GRUB to GRUB_CMDLINE_LINUX_DEFAULT=”i8042.reset quiet splash” . No change.

The mouse trouble is gone after I tried

sudo ubuntu-drivers autoinstall

The keyboard issue remains, though.

The keyboard issue was my mistake -I'd enabled "Mouse Keys" in Assistive Technologies. Embarrassing, but it would seem I'm not the first ;-).
