Hi, Sorry if I have sent this to the wrong list, this is my first posting to the list and so please do go easy on me. I looked for archives to search but couldnt find any. Also I saw the phoronix forum; is that the place I should be asking or these official lists?
this seems to be a related thread: http://phoronix.com/forums/showthread.php?24646-Zaphod-w-multiseat and http://www.phoronix.com/scan.php?page=news_item&px=NzQxMg and http://netpatia.blogspot.com/2009/06/multiseat-in-ubuntu-904.html but they are using Xephyr (is that the current and right way to do it?) I am using MythTV. In case you havent come across it; MythTV seperates TV recording daemon from the presentation of playback, called a backend and a frontend respectively. A master backend is the backend that also runs the MySQL instance. I have recently moved my combined master backend/frontend from a cupboard near the lounge downstairs to a cupboard above the lounge upstairs, which has the added bonus of also moving the machine to within 5 metres of both primary viewing locations. I am therefore looking to use multi-seat linux; although I dont mind if both sessions are actually logged in to the same user, but I would want the power management to turn the monitors on and off independantly depending on usage of the respective "interface". The box is a Q6600 based system, 4gb ram with nvidia 8500gt/512MB (dvi-d, vga, svideo outputs) and using ubuntu 10.04LTS 32bit,myth 0.23.1 and the proprietary nvidia drivers (196 series I think). So this is my plan/desire... Using a single graphics card (either the currently installed one or if required; upgrade it to a new one)... - VGA output of graphics card and USB speakers run to bedroom - DVI-D output runs to lounge and digital audio output from MB runs to AV receiver which then powers the left,centre&right speakers (no surround sound) both are independently to be controlled via a combination of PS3 bluetooth remotes (currenlty using the uinput module - http://www.mythtv.org/wiki/Sony_PS3_BD_Remote#uinput_kernel_module_method) and network control So, my questions: 0. How should I do this, what is the preferred/supported x configuration; or is it not possible? 1. is anyone doing this or something very similar and is there a guide to do this that someone has used to implement this and recommends? 2. is the graphics card 8500gt up to the job - I have been using it in dual head mode for sometime with no issues. 3. how do I segregate the bluetooth signals (for the remotes) to the different "seats", will I need to find an alternative to uinput? 4. I am using VDPAU currently; I assume I should disable this for one of the frontends, What would happen if I leave it on and both systems attempt to access vdpau at the same time; will the second frontend silently fail to get the resource and drop back to cpu decoding or a user noticable error? 5. the same questions as 4, but with a gt430 card instead! ? 6. anticipated upgrade of linux issues? 7. anticipated upgrade of mythtv issues? I have seen and read threads about this; but these specific questions have never been answered or are very old. I also saw and read the thread on dual-head / multi-frontends... but thought this was different enough to deserve its own thread. thanks for your time.
