Hi, I've been fiddling around with Xpra as a replacement to the
Bumblebee Project's VirtualGL backend. Bumblebee permits access to
the Nvidia GPU on Optimus laptops. By using the X server it creates, we
can start applications on the invisible Nvidia screen.
I want Xpra to replace VirtualGL as the transport method, but I need the
screen to display at a normal framerate.
I've included a demonstration that compares rendering through Xpra and
without it. Feel free to drop by #bumblebee-dev on Freenode if you have
ideas or questions.
1. Start Bumblebee X server on :8
2.Start Xpra server
xpra start :8
3. Attach :8 to :0, the Intel screen
xpra attach :8
4. Start applications on Nvidia screen
5. Repeat step 4 as necessary
