>Description:
Unplugging the USB keyboard causes a thin and irregular
horizontal stripe appear near the top of the screen (xorg
6.9.0) across almost all its width. Moving the mouse (either
USB or PS/2) causes this noise to change shape. The
consistency of the system doesn't seem to be affected by this
stripe, though. Occasional random characters have been
noticed coming from the USB keyboard, like a stuck key, once
replugged, but I couldn't repeat it reliably.
The noise on the screen is of one uniform colour (red on my
desktop, green on my laptop).
Looks like someone is spilling data on the frame buffer.
>How-To-Repeat:
Start the system.
Start X11.
Unplug the USB keyboard.
Move the mouse about.
