I am on Natty 11.04.
I have been noticing that upon wake-up from a long inactivity, the screen is not responding to any keystrokes. The mouse is moving though.
This is happening when I am on AC power. The power settings for on AC power are :
- Put computer to sleep ... = Never
- When laptop lid is closed = Suspend (The issue happened when laptop is open and screensaver is ON)
- Put display to sleep when inactive for = 0:15
- Display brightness is 100% and Dim display option is not selected.
Not sure why this is happening. Need your help please to understand the problem and correct it.
