Explanation: Changing the Video mode to any other resolution fixes the display problem but on the other hand it disables the keyboard and mouse. This happen because some of the power management feature in the LFC/DRAC put the DRAC keyboard to temporary sleep when not being used. In this specific installation, for some reason the keyboard and mouse never came back up after sent to the temporary sleep. The usbcore.autosuspend=-1 parameter forces it so stay in action all the time and fixes the problem.
