That's not the target goals. Did you read the wiki page I pointed to listing the goals? https://wiki.gnome.org/Design/OS/DualGPU > You shouldn't be caring about the MUX. I never talked about the MUX, didn't plan on using it either. <snip> > So I'm missing what the overall goal here is.

I'd be interested in supporting USB displays, but I only have proprietary drivers for my USB3 DisplayLink dock, and possibly networked display devices, but the AirTame I have is also still using an undocumented protocol. > Under X, Fedora carries a server patch to autoconfigure providers, > we'd need to drop > that and have something in the DE notice when a new provider shows up > and configures it, > perhaps something to allow removal of providers that are already > bound > (so we could detach > a secondary GPU for boxes to passthrough). I'd rather have that be automated so that Boxes can tell you what is using the 2nd GPU, not requiring any manual intervention. > Then we need something in the DE to allow us to launch or have some > app info that would > decide to launch certain 3D using apps on the more powerful > processor. That's what I started working on, exporting the fact that 2 GPUs are available through a D-Bus service, which also ensures that we only > However since > nouveau doesn't quite reclock most of the secondary GPUs that can > often end up not being > that much more powerful.
