Occasionally, my keyboard and mouse suddenly go into some unresponsive state.
Symptoms of this state:
- Seems to occur randomly, sometimes multiple times per day
- Pressing Esc seems to be the only way to exit this unresponsive state.
- There is no audible or on-screen notification of this change
- While in the state, the Caps Lock and Scroll Lock LEDs flash back and forth
I tried disabling all startup programs, but the issue still occurs.
The keyboard and mouse are both generic Dell ones.
What is causing this behavior? Where do I disable it?

Sounds like a KVM Switch programmable mode, rather than a bug. It looks like on some packages, the control key is an alternate mode-switching key and a double-tap (a common occurrence) puts you in programmable mode.
I am reminded of the Windows sequence of 5 rapid taps of the shift key putting you in Accessible mode. Many people would inadvertently enable Sticky Keys while playing FPS games.
