Sometimes, randomly (as far as I can tell) I can’t click anything (can still move the pointer). I have to restart the computer to have it running again. Same thing is happening on 2 computers, one is Xubuntu, another is Lubuntu. One is 18.04, another is 20.04. But it also happened on plain Ubuntu as well. What’s going on? It gets really annoying. One mouse is Logitech, another one is from Microsoft. Both are wireless. Btw, important note, the mousepad stops responding to clicks as well during that time. Thanks a lot.
