I have installed Ubuntu 20.04 on my dell laptop(Inspiron-5420). Wi-fi connection did not work out-of-the-box with this installation but after google search, I bumped into page
https://ibcomputing.com/install-wifi-driver-broadcom-bcm43142-linux/
and after following the steps there, it started working.
Now when using the logitech wireless keyboard/mouse(model MK220), the keyboard intermittently disconnects and then auto reconnects. The other peculiar behaviour I see is that whenever it disconnects, it automatically takes the screenshot and saves it.
Can anyone out there help in resolving this frequent disconnection issue of wireless keyboard?
