Plugging X.Org GPU Hot-Plugging Into Mainline
Phoronix: Plugging X.Org GPU Hot-Plugging Into Mainline
Earlier today was the first round of comments by David Airlie regarding the finishing and up-streaming of his X.Org GPU hot-plugging support. This allows for new GPUs to be dynamically added to a running X.Org Server environment...
Does it mean that it will be possible to switch between discrete and integrated GPU without restarting xserver?
Not yet. But that will be easier to implement when this hotplugging code is merged into the X server.
