Default Re: NVIDIA Developer Talks Openly About Linux Support

You have to edit your xorg.conf to get that, which means you lose a lot of flexibility and it means you need root access. There is no user-level way to preserve your screen configuration between sessions with twinview.
There is a perfectly well-functioning graphical utility called nvidia-settings which lets you set your screen configuration. This utility can even create an xorg.conf with your current configuration. The only part which is at root-level is the writing to xorg.conf part.

The other options that can be configured via nvidia-settings are actually stored in your ~/.nvidia-settings-rc file. These settings can be loaded by making your WM or DE call "nvidia-settings -l" on login.

nvidia's configuration is also exposed at some level. Hence there is this utility called disper (look around in this forum) which is a command line utility that can change your resolution on the fly (for example on login).

It is entirely inaccurate to assume that a large portion of xrandr functionality is missing when you use nvidia's drivers.
