Fedora Users — Re: Help with Nvidia TwinView Setup

Hi Chris,

chris clarke wrote:

	I'm hoping someone has done something similar and can pass along an
example .config file.  Here's what I'd like to do (if possible)  I have
an Nvidia card with TwinView+TVOut.  Is there a way to set it up so that
my "desktop" remains unchanged (ie everything stays on my Monitor) and
only specific programs (ie gmplayer) run on the TV?

	I've got the Nvidia drivers installed, and have changed my
XFree86Config file accordingly, everything works (Tux Racer, UT2003
etc)  I briefly had TwinView almost working (since lost the config file)
but it was stretching the "desktop" over both the monitor and TV and not
scaling properly on the TV.  Any help would be appreciated, TIA

What i did was use the "multiple screens" configuration, detailed (sort of) in the NVidia readme. Here are the relevant parts of my /etc/X11/XF86Config:

--------------------

The advantage of this is that your monitor doesn't have to be in one of the compatible TV modes: 1024x768, 800x600, 640x480, and your workspace is unaffected by the TV out.

To use the TV, just send any X window to the second screen of the primary display:

mplayer -display localhost:0.1 -vo xv -fs Foo.avi

I even got this working with the MythTV client. Now (well, after i get LIRC working properly) my g/f can watch downloaded TV episodes while i do "work" on the computer.

Good luck,
Mike
