I recently installed Ubuntu 11.04 using a CD .iso. Installation went fine. Upon completion I rebooted and after a second or two I got a black screen with the message "Input signal out of range". And there it sits...

Read a few things about how this could be related to screen resolution, refresh rate, etc. For the heck of it I tried a different monitor. The result is the same but the message provides some clues - "Mode not supported - H:92.7kHz, V:58.3Hz" (the latter is Hz; not kHz).

So my thought is that I should probably be able to use the 11.04 install disc to "Try out Ubuntu", find and edit some file that was created by the install with the correct values. Problem is, I am not too sure what I am supposed to edit. Looked at the xorg.conf file but this is so minimal at this point I am not sure it is where I want to go.

By the way, the monitor is an I-Inc ix191a. Anyone have any ideas on how to get around this?
