Yes. I replay your msg.
And yes to. Any program I start using with prime is working and well. same the vmware 9 that with intel driver the 3d is a mess. Seems working better now. Less problems.
But mine wish was to start ubunt/unit/compiz with this by default. Now with the unity/unity-greeter/compiz. The parser files inside /usr/bin "unity" and "compiz" arent used anymore.
MAYBE this kind of hardware like mine work when using the "--setprovideroutputsource" mode ( like the usb one) . But I didn't test this. since when I use this in mine AMD card. The screen freeze because there is not the EDP/output configured. I need enter by ssh to try it.
Ohh. but when using the ofload PRIME the both cards still working together. If you disable with vgaswitcheroo everything crash. and STILL no a way of SWITCH the card. INTEL/AMD.
But the PRIME OFFLOAD is working 100%.
