Package: freevo
Can anyone supply a configuration example for the following, and advise
if there are any technical limitations that might make it impossible?
Single NVidia video card with two outputs:
:0.0 is a large DVI flat screen
:0.1 is a PAL display (i.e. using the TV out feature on the NVidia
card), although this could also be a DVI
:0.0 needs to run a regular Gnome desktop, screensaver, users switching
sessions, etc
:0.1 is intended to display the video output from various sources
(DVB-T/S, DVD, content recorded by freevo) and it would be nice to have
the freevo interface instead of metacity on this screen
The two need to work independently: when users logout, switch sessions
or activate a screensaver on :0.0, the freevo output should continue
un-interrupted on :0.1
However, I can't quite figure out how to achieve this. A few ideas
occurred to me:
Possible solution 1:
- move the Device and Screen stuff for :0.1 from xorg.conf to xorg-tv.conf
- define a second server in gdm.conf:
[server-tv]
name=TV server
command=/usr/bin/X -audit 0 -config xorg-tv.conf
flexible=true
- observed that gdm starts two X processes, as desired, but the :1
process can't get access to the video card (it seems to be taken
exclusively by the X :0 process)
Possible solution 2:
- split the ServerLayout into two separate ServerLayout sections in
xorg.conf
- this is also unsuccessful, X seems to only allow one ServerLayout to
be active at a time, and a single X instance doesn't seem to be able to
serve different display numbers using different ServerLayouts simultaneously
Possible solution 3:
- find some way to make a process take control of session :0.1, no
matter which user session is active
- disable screensaver on :0.1
Can anyone comment on any of these possible solutions, and whether there
is a way to achieve what I want?
I know I could fit a second video card and then the second X process
would work (solution 1 above), but I am trying to minimise noise and
power consumption. My 8600GT is passively cooled and uses less than
40W. Any extra card in the machine seems to boost the noise level.
