I was reading about Ubuntu’s unfortunately exclusive nvidia-prime package, which seemingly allows to switch GPU used for entire desktop environment on Optimus systems.
Ubuntu’s nvidia-prime seems to be an implementation based on Nvidia’s recent initial Optimus support, or something like that.
Then, found this thread. The 2 most remarkable points here would be:
–There seems to be confusion with the “prime” name here. PRIME itself is indeed what mr Wolfi just mentioned in the post above, but for some reason Ubuntu people named their thing “nvidia-prime” as well.
–Ubuntu’s nvidia-prime probably does a thing (though graphic and automated) similar to what Nvidia doc ch. 33 describes and also altering lightDM by using a startup script, and according to user Tyler_K it should not be that difficult to manually implement…
I read comments in other forums saying that nvidia-prime has better performance than Bumblebee and primusrun, since these ones normally introduced lag (the topic was about Steam and games on Wine). Besides, it would be a bit better if one can switch GPUs for desktop environment at will.
Could someone tell if there’s a way to mimic Ubuntu’s nvidia-prime package? Wish Tyler_K could be around here…
Thanks beforehand.
