i am using one of the cheapest wireless keyboard available in our country (Zebronics make). It was working fine earlier. I was not using it for sometime (because i got laptop keyboard). I tried it recently it is not working.
the usb receiver is plugged in and i got a new battery. when i press certain keys multiple keys are being printed on the screen. can someone guide me on how to resolve this.
Try plugging your dongle into a different USB port.
I was researching on what was going on keyboard. Thought my keyboard is dead. I was researching on some split or ergo keyboard for programming related stuff. Now, i am able to conclude it is not available in India or it is very very pricey. So got an idea to remap my existing keys. This way i can work with the similar mods for future keyboards. there are many excellent works in this regard. decided to go for kbct, thanks to archwiki.
then i am able to run the test to figure out what is happening with my keyboard.

Now when i press a key i can clearly see several unrelated keys are emitting signals.
