Yes.

We have xdriinfo(1).

Depends on your card type and model. Many cards are not supported because
require proprietary drivers and privative firmwares. This cannot be
conceivable in a Free Software project. Nouveau is not included in Dragora
because his position is not clear[1].

The kernel used in Dragora is not the vanilla kernel taken from
www.kernel.org. Our kernel is from http://linux-libre.fsfla.org -- which
maintains a blacklist with the (non-free) hardware unsupported[2][3]:

- Try configuring Xorg: xorg -configure
- Try using the free video driver: nv
- Or try the VESA configuration file - located on /etc/X11

I don't know if you'll have the acceleration...

Good luck,
