[18:36] <sok> on an optimus graphics card i have to query the gpu information via "optirun nvidia-settings -c:8 ..." and by default, in /etc/bumblebee/bumblebee.conf:
[18:36] <sok> # Card power state at exit. Set to false if the card shoud be ON when Bumblebee server exits.
[18:36] <sok> TurnCardOffAtExit=false
[18:37] <sok> so... if turn on the graphics card via the applet, it immediately starts querying itself, which in turn switches the card off
[18:38] <sok> either, i open an idle optirun thread when the button is clicked, or the button will have to be made read only
[18:40] <sok> ugh and this is all the wrong channel but still relevant :P
[18:40] <tjaalton> btw, /usr/lib/nvidia337/ is not provided by any official package, so if you install from external sources you get to keep both pieces
