glx-alternatives 0.6.92 from git

this comes with a lower priority nvidia/bumblebee alternative for glx
which needs to be activated manually


always run
  dpkg-reconfigure glx-alternative-nvidia
after
  update-alternatives --config glx

(and similarly reconfigure nvidia-alternative (or
nvidia-legacy-*-alternative) after changing the nvidia alternative)

to activate and run the triggers

(THIS NEEDS TO BE DOCUMENTED)


since that will 'modprobe -r nvidia'/'modprobe nvidia' you may end up
with the wrong^Wproblematic permissions - are you in the video group?
