I recently upgraded from Ubuntu 18.10 to Ubuntu 19.04 and the ordeal has left my mouse nonfunctional. In fact, all input devices are no longer functional except the keyboard. I'm using a Lenovo Yoga C930

The behavior is just odd.

On startup before login, everything works normally. After login, the computer simply doesn't respond to input (touch screen, mouse, and keyboard); however, if you close the laptop and then reopen it (no other way to force a lock screen), the keyboard starts to work again. The mouse does not start working.

If you open a few windows, many keyboard functions stop responding. You can still alt-tab to switch between windows and use the home key to display all windows; however, shortcuts to open a terminal or tabbing through windows no longer works.

I haven't seen anyone else have this problem and would rather not do a clean install. I'm not even sure if that would be possible for me.

    You probably have a GNOME extension problem. Get to the Recovery Mode # prompt, and type ls -al /home/username/.local/share/gnome-shell/extensions. Show me, or tell me, what you see there. I'm only interested in the filenames. – heynnema May 7 at 20:49
