Right after startup, my mouse works perfectly fine (sometimes takes a few seconds to register, but good after that). However, a few minutes into using Ubuntu (has happened in both 16.04 and 14.04), the left click stops working for part of the screen.
Here's what I can do when this happens:
- Move the mouse anywhere on the screen.
- Keyboard works perfectly fine.
- Hover over items in the dock to the left (my list of applications).
- Sometimes even this doesn't work, though.
- Click on items in the dock to the left and have the application launch.
- Sometimes this fails too.
- Hover and click on items in the top menu bar for the application.
- Sometimes right clicks will be registered in the terminal, as well as being able to select text in the terminal.
Here's what I cannot do when this happens:
- Interact with any application on the main screen (click on links, switch to a new window, etc.)
- Select text in the active window.
- Right click in the active window.
- Scroll using the scroll wheel.
Things I've tried to resolve the issue (but none work):
- Check the power settings for my USB devices (they're all on).
- Check to make sure the mouse (Corsair M65) works on Windows (it does).
- Plug the mouse directly into the PC instead of my keyboard's USB port (no change).
- Checked my system log with
tail -f /var/log/syslog(nothing shows up).
- Listen for the mouse click event with
xev(keyboard events show up, but mouse events do not).
The only thing that I can do to get my mouse back is to reboot.
I don't notice a trend of which this happens, but I did notice it happen one time after launching the terminal, not sure if that was related or not.
Any ideas on what I should do besides a clean Ubuntu install?
EDIT: Found something that fixes it (temporarily)! Thanks to this answer, I have discovered that hitting
ALT + CTRL + F5 and then
ALT + F7 gives me full control over my mouse (until I lose it again). Better than nothing, but a permanent solution would be greatly appreciated!
