Single-GPU Multi-Seat Support With X.Org Under Xephyr

Written by Michael Larabel in X.Org on 2 April 2015 at 08:20 PM EDT. 12 Comments

A patch series that's been baking for a while by Laércio de Sousa provides Xephyr input hot-plugging and other changes needed to allow for single-GPU multi-seat support.

The ten patches by Laércio are now up to their third revision for providing full single-GPU multi-seat support under Xephyr, the X11 server implemented with KDrive that in turn targets a host X11 Server's frame-buffer for rendering. The input hot-plugging support is exposed for the HAL and UDEV back-ends inside KDrive.

Having this full multi-seat support off a single GPU in Xephyr amounts to just a few hundred lines of code. More details via this patch series.
