! DGA is short for Direct Graphics Access and is a means for a programm to
bypass the X-Server and directly modifying the framebuffer memory.
Technically spoken this happens by mapping the framebuffer memory into
! the memory range of your process. This is just allowed by the kernel
if you have superuser privileges. You can get these either by logging in
! as root or by setting the suid bit on the mplayer excecutable.
! There are two versions of DGA: DGA1 is used by XFree 3.X.X and DGA2 was
introduced with XFree 4.0.1.
! DGA1 just provides direct framebuffer access as described above. For
switching the resolution of the video signal you have to rely on the
XVidMode extension.

Those are defined by so-called modelines and depend on the capabilites
of your video hardware. The XServer scans this config file on startup and
! disables those modelines not suitable for your hardware. You can find
out which modes survive with the X11 log file. It can be found at:
! /var/log/XFree86.0.log (on Debian systems ... :-) )
See appendix A for some sample modeline definitions.
