Ubuntu 11.10 Server black screen
So I am having and issue with my server. I took it offline for a while for general maintenance after installing updates. When I went to reboot the server, right after the system POSTs it stops at a black screen and the monitor says no signal. Any help with this would be greatly appreciated since the server cant suffer any lengthy downtime.
