Description

Hi, we currently use XF86VidMode for X modesetting.
However, it's old (and in our current implementation, broken on 64b), and obsoleted by the XRandR extension.
So, we should drop XF86VidMode and use XRandR instead.
For the record, Id Software did that with its game "Enemy Territory: Quake Wars" on GNU/Linux a few years ago, so, it shouldn't be a problem with any decent video driver, now.

I think xranrd could be nice indeed. If you have a patch, we'll take it :)

NVidia proprietary driver is using refresh rate as unique ID to identify resolutions (XF86VidMode was detecting correct refresh rates).

That's why XRandR returns 50 Hz instead of 60 Hz.

So I decided to use XRRSetScreenConfig (XRandR 1.0) instead of XRRSetScreenConfigAndRate (XRandR 1.1)
