Better Monitor/Resolutions Support

Registered by xtknight on 2007-01-15

Ubuntu should automatically be able to properly detect a monitor's resolutions and refresh rate using the DDC/EDID information. This would save a lot of hassling around with Xorg reconfigures. It would seem that this is only partially implemented. ( See https://help.ubuntu.com/community/FixVideoResolutionHowto )

A user should be able to define a custom resolution and refresh rate in the resolution dialog. There should also be options here for controlling the graphics chip's LCD scaling mechanisms (video card scale, monitor scale, centered mode, aspect ratio scaling). For NVidia, these options are provided in the proprietary NVIDIA driver's Xorg options.

For LCDs, it should choose the native resolution and 60 Hz. And, for CRTs, the resolution that works at 75 Hz should be chosen, or if the monitor does not support 75 Hz, 640x480 at 60 Hz. Ideally, widescreen monitors should also work without any extra effort.

2008-04-25 bryce: Pretty much everything described here has been implemented as of Hardy, except control of LCD scaling mode, which perhaps is not something most users will need anyway; however drivers are starting to expose support for this through Xrandr 1.3, so it too will come in time.
