I've installed Ubuntu server 12.04.3 on a HP DL380 G4 and the installation completes with no issues and errors. Once the installation is complete and server reboots in Ubuntu I receive "Out of Range" displayed on the monitor. I've tried installing 12.04.2 and 12.04.5 and received the same message. I've also installed it onto a HP DL380 G3 and run into the same issue. I was able to get it to work once, but after rebooting it reverts back to "Out of Range". I've look through other forms and tried some of their solution, however I can't go but so far because once it boots to Ubuntu I can't see.
