Upgraded my server from Ubuntu 10.04 LTS to Ubuntu 12.04 LTS as per update manager suggestion. I was running 1920 X 1080 under 10.04. Now the video card is set outside the capabilities of the monitor. Have no Xorg.conf file. Where can one find documentation of the boot process and files. Don't mind doing the research, but the forum seem to be a circular treadmill.
Computer Specification: ASUS motherboard with an ATI Rage 128 video card driving a Dell HD widescreen monitor.
