GDM with multiseat support - GDM will manage multiple local displays and has the ability to add/remove displays dynamically.

You can also change the compiler flags and produce a binary under a different name (say displaylink_drv.so instead of fbdev_drv.so). Our package is called xorg-x11-drv-fbdev-displaylink to avoid conflict with the stock package provided by the distribution and it installs the files in /usr/local. This is a temporary solution until Xorg adds support for the damage protocol. The extensions add support for the X DAMAGE protocol.

xorg-x11-drv-fbdev with extensions - Xorg driver based on the fbdev driver.

In RHEL 6 we have xorg-x11-server-Xorg-1.7.7-26 which works perfectly in a multiseat environment.

Xorg - this is the standard graphics server on Linux.

This is useful for easier identification of the display. We also use a custom patch that will draw the string 'fbX' onto the green screen. On RHEL6 this can easily be built as a stand alone module. As of January 2011 udlfb.c is part of the mainline kernel tree and is on track for 2.6.38.

udlfb - a kernel driver for USB graphics adapters which use DisplayLink based chips.

It is also possible to use USB docking stations from other vendors but I'm not aware of anyone who did it. USB docking station like Plugable's UD-160-A or a combination of USB video card and stand alone USB hub. To build a multiseat system you need a number of individual components: We use the name SUMU (simple usb multi user) to refer to the entire multiseat bundle and in this article I'm going to describe the current state of technologies surrounding multiseat, how that works on RHEL 6 and some practical observations. offers full support of USB multiseat for Red Hat Enterprise Linux 6 as a downstream vendor. My company Open Technologies Bulgaria, Ltd. In the last few years USB docking stations emerged on the market and are becoming popular among multiseat enthusiasts. Multiseat configurations are well known in the Linux community and have been used for a number of years now.
