Do you have details or a bug report about these? I haven't used intel gvt-g and on the occasion of skimming through the code - quality was below i915. There is a nasty bug where nvidia prime render offload causes the VM to simply segfault [0]. But intel gvt-g is better than using virgl for 3D stuff on a VM.

Bumblebee still has some uses and also, the it has the appeal of keeping the card completely powered off, something that doesn't happen with prime render offload. Thanks for maintaining these Giancarlo. The power management side of Bumblebee will be untouched - my email explicitly covers only the file side of things. I've seen far too many reports of people using primus, on top of GLVND enabled nvidia/mesa causing all sorts of problems. Since tracking individual reports does not scale - I've put this proposal. Note: having a compat primusrun/optirun/pvkrun makes sense - setting the respective environment variables is annoying. -Emil Put your proposal changes and reasoning on flyspray tickets for each package and I'll take a look. I'm not sure all the changes are needed. And, it turns out that, due to some limitations/issues related to intel gvt-g and nvidia with prime render offload, I'm using bumblebee currently. Only issue I had recently was the xorg autodetection issue that they reverted, other than that, it works fine here. Regards, Giancarlo Razzolini pgpE4IxU3PPan.pgp Description: PGP signature
