Keyboard not responding after login

Hello,

Everytime I log in, the keyboard stop responding. But it works to type my password. I already searched other threads, but it doesn’t really help.

From what I’ve seen in the Xorg logs, it might be because it thinks my keyboard is a mouse. My mouse is indeed connected to the USB port of my keyboard, because I don’t have enough wire length, and in the past it wasn’t an issue:

I’m using 5.4 kernel, but the issue was the same with 5.10. Here is the log from Xorg:

Have you installed some power management tool? Like TLP? I remember enabling some USB auto-suspend feature that gave me similar issues. What happens if you disconnect and connect your keyboard when it is not responding. Is it a laptop or a desktop?

Hello,

It seems that TLP is installed, but I don’t remember installing it. I guess it comes with Manjaro? In the Manjaro’s energy settings it seems it is only configured to stop the screen after 15m and “support for button events”.

Should I remove it? I’m on a desktop and yes, when this happens I just have to unplug + replug the keyboard on the same USB port.

Try installing TLP UI with:

sudo pacman -S tlpui

Then, open the program, go to the USB section and disable USB_AUTOSUSPEND

Let’s see if it works!
