Comment 81 for bug 1181666

I am facing the same issue in Ubuntu 18.10. The super key randomly stops working and I loose control of all windows except for the active window, which in some cases also stops working and cannot even do clicks there. The workaround I found is to close all windows, lock the screen and the problem solves for 5-10 min or so. But this is clearly impractical and I can't really go on like this any further. I re-installed the OS but it didn't solve the issue. I have a Lenovo T430s if that helps. Does anyone found a solution to this yet? I'd appreciate it very much!
