What is the current (preferred) (year 2020 - Kubuntu 19.10) way to switch between nvidia (RTX 2060) GPU and iGPU (Intel UHD Graphics 630)?
i am interessted in both: - nvidia with official drivers (version >=440.64) - nvidia with nouveau
and iam also not sure if it is possible to do this live (without reboot / relogin)?!
the posts & questions i found about Optimus and related things are mostly predating 2016...
nouveau.freedesktop wiki page for Optimus was last edited 2015-01-09
and if i try to follow the infos i find very varying outputs - and don't know if my command results are just wrong because i have missed something or because it is just outdated / has changed in the meantime...
so it is hard to know where to start...
hopefully anybody has a good idea on this or and links to uptodate information ;-)
really nice would be if someone has a system setup that allows for 'live' switching between nouveau and nvidia drivers..
(there was a unanswered question in this direction from 2016 and a answered one from 2010)

. see How NVIDIA On-Demand option works in NVIDIA X Server Settings? at least for application switching (don't know if powering is done automatically..)
