proprietary nvidia drivers broken since 16.04 [SOLVED!]

So I got nvidia prime working with the nvidia-367, but:
-- could not switch live (aka bumblebee/primus/optirun)
-- when running in intel mode (prime-select intel) Chrome browser
would hang in individual windows a lot. could not even get
into chrome://settings to change anything...
-- laptop ran really hot.
So I went back to entirely stock repos (so nvidia-361), and followed
these instructions to get bumblebee/optirun/primus working:
Had to do it a couple of times because various bits got corrupted by
various other activities, but eventually got to the point where it all
appeared correct, but even then I was getting:
blacklab% optirun glxinfo
[ 102.026241] [ERROR]Cannot access secondary GPU - error: [XORG] (EE)
[ 102.026271] [ERROR]Aborting because fallback start is disabled.
"If you are on Debian testing/unstable or ubuntu 16.04 or any
derivative with Xorg >= 1.18, make sure you don't have
xserver-xorg-legacy installed, as it's incompatible with bumblebee."
apt-get purge xserver-xorg-legacy
( This is perhaps because laptop was 14.04 upgraded to 16.04. )
now it all works. Default Intel GPU, and I put 'primusrun %command%"
to run games, and it uses the nvidia gpu just for that.
runs much cooler in general.
