Comment 26 for bug 1860424

I seem to have this same problem on Ubuntu 20.10. (It was present in 20.04 as well). Recently I wanted to use this keyboard on Windows 10 and it was failing as well (!!). I found this article on it for Windows: https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware-winpc/microsoft-sculpt-ergonomic-mouse-does-not-click-on/a89bc2de-4ee0-497a-b8fa-289338b9bbb1

Seems that this only happens with older version of the keyboard. I bought mine in 2016. The described workaround on windows (ctrl-alt-del and then cancel) has worked.

Similar using Ubuntu if the problem occurs I can use Ctrl-Alt-F3 to change to a console and then Alt-F2 back to my session and it's working again. The mouse will then work for a while but the problem does reoccur intermittantly.

I have not tested this with a later version of the hardware though but am wondering if the orignal reporter is using an older hardware version as well.
