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. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
