20.04 Key lagging issue with gsd-media-keys log?

Question

I got my 18.04 Ubuntu upgraded to 20.04 several days ago.

After the fluent upgrade, there's keyboard lag issue several times a day.

Keyboard lag issue means, keyboard input is not working at all for about 5~10 seconds.

During this keyboard lag, there's no issue on mouse input, which is using the same USB receiver.

Plus there're following logs when I have the keyboard lag issue.

I have no idea about gsd-media-keys event, Gio.IOErrorEnum and JS ERROR at all.

Can anybody suggest the reason of this issue?

Answer 1

I am leaving an answer by my self, to share my experience.

For summary, above logs are not related to key lagging issue.

After I reinstall(apt purge & ubuntu-drivers autoinstall) nvidia drivers,

there's no more key lagging issue.

(And above logs are still remaining.. So it's not related to key lagging issue)
