That's correct for nVidia binary drivers. For KMS drivers (modesetting/nouveau/intel) there is now bumblebee-like support for offloading single program to discrete GPU. It does not require completely separate X server and is more efficient than bumblebee, but it won't work with nVidia drivers for several reasons.
do you have a link? I'm very interested
I'm feeling like google expert ...
I see no difference with https://en.opensuse.org/SDB:NVIDIA_Bumblebee http://dodin.org/wiki/pmwiki.php?n=Doc.OptimusVideo#toc8 and it work (or seems to) on my computer, with no change since several month except regular openSUSE updates. Bumblebee is said to run, optirun kdenlive start kdenlive, no immediate way to see if it's really better linux-owxt:/home/jdd # optirun --status Bumblebee status: Ready (3.2.1). X inactive. Discrete video card is off. linux-owxt:/home/jdd # optirun glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 6240 frames in 5.0 seconds = 1247.935 FPS what I notice is that I can change # cat /proc/acpi/bbswitch 0000:01:00.0 OFF not even with vi (it's immediately reversed) best guess is that some bug was fixed in newer kernel (if it works) my asus computer is of the second kind as said here https://01.org/linuxgraphics/gfx-docs/drm/gpu/vga-switcheroo.html "Dual GPUs but only one of them is connected to outputs" thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
