To get normal Multihead, just add Screen options to your normal Layout. Now create a 'Screen' section for every monitor-videocard combination.Īfter this it's time to set up a multihead 'Layout' section in the XF86Config.
#Linux multimon driver#
The other configuration options of the driver should be only used in the device section of the primary head.Įach monitor should have a working 'Monitor' section. This would indicate that this particular device section if for the primary head, the other device sections should have a similar option, but with the number increased. Each Device sections needs a 'Screen' option with a number.
In most cases these cards have a second entry in lspci/scanpci.Įach head on the card should have a seperate Device section, each with the same 'Driver' option but different 'Identifier and'BusID' options.Ī special option needs to be added for multihead configuration. (Note that even AGP cards use the 'PCI:' prefix)įor single videocards that support multihead it depends on the used driver. The proper BusID can be found by using lspci or hwinfo -pci. (Test this by using it as the single output).Īdd a matching BusID option to each Device section so it knows which driver to use for each physical device. In other bios: Bios First Boot -> Įach videocard should have a working 'Device' section. In AWARD BIOS menu: Integrated Peripherals -> Init Display First -> AGP
Note: Many people have found that having agp as the default boot screen is required if you are having problems try this out. Login to default a command line and try calling Remember to backup your original nf:Ĭp /etc/X11/nf /etc/X11/ Some basic knowledge of the config file is needed for this. Chose if your screens are aligned horizontally or vertically. Chose "Activate Dual Head Mode" and click on "Configure". Start yast2, chose hardware->Graphics Card and Monitor. So, find out your distribution and read on.

Note: It's also possible to use the Voodoo1/2 3D-only add-on cards as an extra output, see the Glide driver manual page.Ī window manager that supports your chosen multihead method.Įspecially for Xinerama it's required that the window manager supports this extension (both KDE and Gnome support it).įor TwinView and MergedFB it's not needed, because these methods 'fake' one big desktop for the xserver itself.ĭepending on your distribution there are different steps to take to get to your multiple monitor setup. This requires special support in the XFree86 driver.
Using a single multihead capable video card.
#Linux multimon drivers#
MergedFB - New method supported in some xfree86 drivers, currently mga,sis,ati drivers (These last two only in recent experimental/CVS versions)įor the video cards different methods are available:.ATI's Big Desktop - What the ATI drivers call it.Nvidia's TwinView - What the Nvidia drivers call it.There are a couple different implementations for this: Combined mode - The different monitors are combined into one big virtual screen.'Normal' MultiHead - Every monitor has a different seperate X screen and session.Clone mode - Every monitors output the exact same thing.There are a couple of different layouts possible:
