Ask Slashdot: Hardware Accelerated Multi-Monitor Support In Linux? 278

An anonymous reader writes "I'm an Engineer with a need for 3 large monitors on the one PC. I want to run them as 'one big desktop' so I can drag windows around between all three monitors (Windows XP style). I run Debian and an nVidia NVS450. Currently I have been able to do what I want by using Xinerama which is painfully slow (think 1990s), or using TwinView which is hardware accelerated but only supports 2 monitors. I can live without 3D performance, but I need a hardware accelerated 2D desktop at the minimum. What are my options? I will happily give up running X and run something else if I need to (although I would like to keep using Xfce — but am open to anything). I am getting so desperate that I am starting to think of running Windows on my box, but that would be painful in so many other ways given my work environment revolves around the Linux toolset."

    Followed by the stupidest answer ever!
    Congratulations to the both of you.
    Well, mostly to the answer, as the question really isn't that stupid at all.

    I'm afraid there's simply nothing for Linux that will easily do what you want.
    Multi-monitor - even with only 2 outputs - support is bad.. personal anecdote:
    - Debian Wheezy with 3.9 kernel from Sid
    - Lenovo 2011 era laptop (Thinkpad Edge E420)
    -> when connecting both internal screen (LVDS) and to a beamer for presentations, if the output is set to beamer only and the VGA cable is removed, display will not be reset to LVDS only, making the laptop unusable
    -> when connecting three displays (VGA + LVDS + HDMI), really bad things happen (outputs black) if the laptop goes to suspend..

    It's trivial on linux as well if the hardware can do it, and the GUI tool to set it up looks just like the MS Windows one. Your "royal PITA on Linux" is just telling us you have an axe to grind and are willing to bring it out over a non-issue.

    /etc is the one place where configuration files are located for Linux /etc/X11/xorg.conf is the one file you need to edit to configure X
    last time I checked there were not a billion files there

    If you think Windows is easy to use, then that's ok and a matter of choice and opinion. But stop pretending you do know anything about "Linuks"
