Hi,
the keyboard input sometimes does not get registered by the OS. The keyboard input randomly stops working, even though the mouse and touchpad are still working. After a while (couple of minutes) it usually resolves. If not, I need to restart the computer. I tried plugging in an external keyboard when this occurs, but that does not work either.
This issue started when I reinstalled my system with hard drive encryption (LUKS). Before the reinstall I never noticed this problem.
The interesting thing is, that when I press the caps lock key, the indicator light of the caps lock key starts lighting, which tells me that this is not a hardware issue. I can toggle the caps lock without a problem, but none of the other keys seem to get registered by the OS.
Also, if I open up a terminal with my mouse, then the cursor block is not solid, but just has an outline, the same way when the terminal window is not focued. What I mean by this is that when everything is OK and the keyboard works and I open up a new terminal the terminal has this type of cursor: █ (block that is filled)
But when I open up a terminal in this “halted” state, when the keyboard is not responding it is like this (just like as it would be when a terminal is open but it is not the focused window): ▯ (block that is not filled)
Also, this issue occured more often after starting the system, but after I removed psensor from application autostart, it almost never occured anymore on startup.
I don’t know what could be the cause of this, but I suspect that some process could “halt” all keyboard input for some time. Any help is appreciated.
