I've been running the beta with no problems at all on my nVidia 5700. Was running at a proper resolution.
As am using this just to learn Linux etc, i did a clean install from the new RC client. And i've simply not been able to get the resolution above 640x480 since. I've enabled the hardware driver etc, and i've got X server to try and change the settings, but i cannot find the place where i tell ubuntu what the monitor actually IS.
It used to be there in the Applications drop down, but its gone I was SO hoping to get it all working without having to ask but looks like i've failed
Can anyone help point me in the right direction where i can configure the monitor settings, preferably without having to use text editor and xorg.inf
