I have found a strange problem in my Ubuntu 12.04 laptop.
When the machine is started, everything is working fine. But if I press the Right Shift key, the keyboard starts to work abnormally as follows -
- All the letter keys is displayed in uppercase even if the caps lock are off.
- Number keys are not working.
- The Right Shift key is not working anymore.
I could not find any clue how to solve this. Any suggession is appreciated.
