Xinerama is not really useful for independant displays as they are not,
well, independant. You will have issues with the focus being shared
between the screens, so even if you managed to get two mythtvs running
on each screen (and I'm not sure if that is possible) you would only be
able to control one app at a time.
I would recommend you follow Chris Tylers instructions on how to setup
multiple Xservers using xorg 6.9/7.0 as this allows you to use multiple
video cards as completely independant displays. So the displays each
have their own keyboard, mouse, resolution, window manager, etc.
The instructions can be found here -
I have used these instructions to add another seat to my debian etch
home pc. I can now do my work while the kids play games or watch tv on
the other monitor - even though the second card is an archaic S3 4MB PCI
card, it still plays SDTV fine.
The issues I encountered have all been documented on the above blog, but
* I needed the -isolateDevice command in the xserver invocation lines at
the bottom of my gdm.conf (apparently this is not always required).
* I had to disable the terminal blanking to stop the second seat
blanking and never coming back to life. Under debian this requires
editing of /etc/console-tools/config as follows:
(On other systems, just grep /etc for setterm and try and determine how
to modify it appropriately).
Hope this helps, I have been very impressed with the stability and
utility of this setup and the kids are loving it. I have had a few
issues with python games crashing and consuming 100% cpu, but it is
trivial to kill off the process when you have another logged in screen
sitting next to it.
Athlon XP 2400+ (800+MB RAM, 80GB HD)
2 * 19" CRT
2 * USB Mouse
2 * USB Keyboards w/ builtin USB Hub ( I was already using usb
mouse/keyboard but you could also use a combination of USB and PS2).
USB extension cable
DSUB extension cable
Audio extension cable
(The extension cables aren't required, but I like to have the kids a bit
away from my work space.... they can get a bit rambunctious).
I hope this gets you on the path to multiseat bliss - remember you don't
need the latest components (the PCI video card thats been sitting in
your cupboard should be fine).
The only issue I have not yet faced is directing audio to an appropriate
sound device on a per seat basis. Currently all audio streams go to the
one output device in my setup, but the kids are pretty much the only
ones who use sounds so it's not a big issue in my case.
