Independent Dual Monitors On CentOS 7

Does anyone have the magic incantation required to getting
*independent* multi-monitors going under CentOS 7? Ideally under xfce or trinity, but I’m interested about GNOME/KDE
observations as well.

I’m trying to move my main workstation from CentOS5 to CentOS7
and while the spanned desktop works, not having independent monitors really cuts into my productivity. i.e.: I couldn’t care less about dragging things from one screen to another, but not having a 3×3 virtual desktop grid on each monitor independently really sucks.

  • Devin:

    i’ve done it on Fedora 20, don’t know if that’s similar enough to C7
    or not, to work the same way, Uinsg Nvidia proprietary driver.

    A couple of caveatrs:
    1. I don’t remember the details, but if you’re interested, I can dig for whatever info I used when figurinig it out;
    2. I got two “independent” monitors, but that means you can’t drag things across monitors. but there also are no menus in the panels of the second monitor, and no desktop icons, by default, so it’s hard to start programs on the 2nd monitor. I recall finding an XML file (somewhere???) that contains what appears to be the setup info for the main monitor, so it may be possible to either hack that file, or create some other file with similar info in it, that will cause the second monitor to be a full-fledged workstation in its own right.


    Let me know if you need me to dig around for info.


  • With GNOME3, the secondary monitors do not have workspaces. That is useful for some workflows, but if you don’t like it you can use gnome-tweak-tool to give workspaces to all monitors. Hope this helps.


  • Myu suspicion is that it can be done by starting two X sessions with the proper parameters. I’d expect this to require tweaking a per-user login script.

    I’ve never tried it.
