I have an IBM XSeries 335 1U Server. It was given to me. It uses a special cable for display, mouse and keyboard.
I boot the OS, everything is fine for a while and then at some point the display goes blank and I cannot do anything with with the keyboard and mouse and the display does not come back.
The machine is working, I can see hard drive activity, The display light is 'green' (not orange like typical display sleep). Pressing a key on the keyboard does nothing, neither does the mouse.
How can I get my display back so I can see what is going on?
