<div dir="ltr"><div><div><div>Hello everyone:<br><br>I'm trying to get three monitors going with a built-in intel chipset and a discrete radeon card. <br></div><div> I have two apple cinema displays and a dell flat panel. I would like the two apple displays to form a single "screen" that I can drag windows back and forth on. The dell monitor will only be used for my monitoring solution and will be static all the time, so I don't need to be able to drag windows to/from it and the apple displays.<br>
<br></div><div>I'm running into one of two problems. <br><br>In my current config, only the graphics card I have listed first (I've tried swapping the order) will bring up X. The other will be blank or show the console depending on the card and will not even be listed in the Xorg.0.log file. If I have the radeon device listed first they are configured correctly as I have described above.<br>
<br></div><div>If I un-comment the layout section in my xorg.conf all three screens come up, but the two displays connected to the radeon card will act like one screen. (My panel bar in KDE stretches across both screens and my yakuake console will drop down on both.) Not what I'm wanting to happen.<br>
<br></div><div>I've also been able to have all three screens on at one time, but not be able to drag windows between any screen. (I can't remember off the top of my head but I believe I had this setup by splitting the radeon card into two device entries and adding a third screen section and having it be "RightOf" screen1 and moving the intel device to screen2.<br>
</div><div><br></div><div>Is what I want possible? Can anyone help with suggestions about config changes?<br></div><div><br></div>Here is the listing from lspci:<br><br>00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)<br>
