I've been using XBMC on my Windows machine successfully for years now. Recently I decided to give Ubuntu another chance and all hell broke loose. After a day of tweaking and rebooting I finally managed to set the sound issues straight, but now I have a problem with dual monitor setup.

In short, my primary works just fine. I can also see a background image on my secondary display (40'' Samsung LE40A656) through Nvidia GeForce 9600GT (latest drivers from their site). It's all set in the Nvidia X server

However, there's no way I can force XBMC to start on that secondary display. There is no such option in the settings (only full screen on monitor #1 and windowed). Nvidia X server settings see both monitors, though Ubuntu's own in-built Monitor setting tab only sees one monitor. Could that be the problem? Any suggestions? I've read numerous mentions of setting some environment variables somewhere, but I have no clue as to what to do with them ("SDL_FULLSCREEN_HEAD"). Anyone?

My xorg.conf is this:

Update: I installed the latest Nvidia drivers from their site (275.09.07). Still no success. Then I uninstalled XBMC and installed the latest version (Jun 16) from GIT, no changes. When I open XBMC and navigate to System>Settings>Video output, all I get is the option to either run XBMC on Monitor 1 or windowed. No Monitor 2 available whatsoever.

Both displays are set in the Nvidia X Server settings app as separate X screens. The TV displays the background image just fine and I can move my mouse cursor there no problem.

Finally, I tried starting XBMC with this command:

This started XBMC, but not on head 1 but head 0 (my monitor and not the TV)
Anyone? Pretty, pretty please...

Submitted a bug report (http://trac.xbmc.org/ticket/11642). Feel free to contact me for additional information.
Cheers

I am having the same problem here with twinview and separate x displays.

Does this blog help?

Here is the fix... if what I think that is your problem.

drivers are way old now please see my signature

Also your xorg, was that auto created or did you manually do most of it?

Anyway some light reading on how to setup various monitors in a cleaner way

For TwinView you have to set up MetaModes to get non-doofy fullscreen I'm pretty sure. The problem is that the one display will turn off when XBMC is fullscreened on the other display. If you need both displays on simultaneously then going with separate X screens is probably the better bet.

For TwinView, in the "Screen" section of your xorg.conf:


Here I set up three MetaModes: 1) Both displays on, 2) Display 1 on and display 2 off, and 3) Display 1 off and display 2 on.

Open up XBMC, go to system settings and switch to "Fullscreen". Then switch resolution to the one that matches your second display.

If anyone knows a better way to get fullscreen on TwinView, please share.

I've never worked with separate X screens but you probably have to identify which display to launch XBMC on, so...

For bash shells:

DISPLAY=:0.1 xbmc

For C-shells:

env DISPLAY=:0.1 xbmc

..would probably work. Or check out the links posted above, especially if you're having problems getting the mouse and keyboard to move between X screens.

Hey guys i got the same problem and i have tried changing my xorg.conf so that it sets the different meta modes, but i still just get 1 resolution, when going to system in XBMC.

Did i miss anything?
