OK, from what I've read this does work, but requires specific configuration in the kernel, in the xorg.conf and the target (DE) desktop environment to work. Also there are several ways to achieve this multi-head system and the final outcome is sometimes constrained by a variety of factors. No doubt this will be a "project" for you. > More information will be provided once I know this is possible. Exact specification of the video cards, your DE, and which method you choose will be needed to google for specific examples and receive help from others. > If the answer is yes, then my next step is figuring out why I can get > either monitor to work alone, but can't get both of them to work together. Yes, let's start with gentoo's page on this: [1] Here are some additional links that, once you read them, you'll have a basis and resources to cut snippets into a highly customized xorg.conf file. [2] Also, do you want one big virtual screen across the (2) monitors, or do you want them to display form different applications? Also do you want a second keyboard and mouse so it can also be used like a second workstation at times? I saw a few sites that talk about how to switch between modes. So define exactly what you want to do and verbosely list your hardware. Then google for specific code snippets and cobble together your xorg.conf. Then we can hack away at that, based on any additional features that your chosend (DE) provides (features or management of hardware). Last, folks are raving about multihead monitor support with LXQT which used QT5, but that all seems to be very news. Once you figure this out, give some feedback to the gentoo docs team to enhance [1]. BGO would be keen for new information on multi headed options. hth, James [1] http://wiki.gentoo.org/wiki/Xorg/Multihead [2] http://www.yolinux.com/TUTORIALS/LinuxAndDualMonitors.html [2] http://wiki.linuxquestions.org/wiki/Multiple_Monitors_with_Nvidia [3] https://wiki.archlinux.org/index.php/multihead [4] http://wiki.gentoo.org/wiki/Radeon [5] http://awesome.naquadah.org/wiki/Using_Multiple_Screens [6] https://help.ubuntu.com/community/XineramaHowTo [7] https://wiki.ubuntu.com/X/Config/Multihead
