Development on such features has been sorely lacking for well over a year as of 2012; if you want to see Linux come up to Windows and Macintosh standards in this area please tell the Xorg developers at http://www.x.org/wiki/XorgMailingLists
The TDE project badly needs these features before it can proceed with graphical monitor configuration tools:
* GPU object support
* The ability to query the active driver name for any Xorg output
To recap, this is not a TDE shortcoming, but rather is the result of a lack of fundamental Linux support for graphics configuration!
