A white circle with a stroke inside a grey box(just like "not allowed"sign) keeps appearing on my ubuntu 20.04 and thus freezing it for like a second or two and goes away and then comes back again(two seconds or three tops intervals)......I tried to remove it by disabling all the audio keyboard shortcuts but the sign wont go away...what seems to be the problem?

Try reading this: not allowed sign flashing on screen and see if it helps you. Your question is a possible duplicate. Im pretty sure it will not though because it tells you to disable a few shortcuts, which im pretty sure you already did, but atleast read it.

sudo showkey. Is there any output when this is happening and you are not touching any input devices? – rtaft Jun 04 '20 at 15:17
