<br></div>Im trying to get X to play nicely. My set up is two graphics cards (well one and the onboard) and three identical monitors.<br>
<br></div>The first is an Nvidia with two monitors connected via DVI. The other is a cr*ppy onboard intel thing with the third monitor.<br><br></div>I have it working fine with Xinerama, but of this then causes issues with Gnome due to randr not playing nice with Xinerama. I.e. it complains that 'Xlib: extension "RANDR" missing on display ":0.0"'. <br>

the most reliable and you end up with GLX on both monitors. I've found ATI's equivalent of twinview to be ok. I'm sad to say that you might <br>
want to just use two monitors or get an Nvidia card with 3 outputs or get 2 Nvidia cards.<br><br></div><div>I think you can use Nvidia twinview across two cards.<br><br></div><div>My desktop is a single Nvidia card with two monitors, and contains the following magic lines:<br>
<br> Option "TwinViewXineramaInfoOrder" "DFP-0"<br> Option "TwinView" "1"<br> Option "metamodes" "DFP-0: nvidia-auto-select +0+0, CRT-1: nvidia-auto-select +1680+0"<span class="HOEnZb"><font color="#888888"><br>
</font></span></div><span class="HOEnZb"></span></div></div></div></blockquote><div><br>I have just tried it again with Xinerama off and using twin view. I've got something but still not 100% there. I now get a separate DE/WM session per monitor. RandR does work but running it in any of the three sessions, it can only see it's respective monitor. <br>
<br></div><div>Im going to RTFM a bit here and do some googlefu, as I've made progress. Cheers.<br><br></div><div>Simon.<br></div><div> </div></div></div></div></div></div>
