1) nvidia 960m, bionic-proposed: everything up to date except for ubuntu-drivers-common. Nvidia driver is working when selected with prime-select but switching to intel (prime-select intel) does not work. Nvidia is still running.
2) nvidia 970m, bionic-proposed: everything up to date. I installed ubuntu-drivers-common and nvidia-prime from Alberto's hybridgraphics ppa. Everything works correctly. Both nvidia and intel modes are working as expected. Nvidia card is now silent and cold (I have 2 separate fan for cpu/gpu) when intel is selected.
Maybe I should retry when ubuntu-drivers-common is updated in proposal?
I've done 2 tests on 2 different machines.
