# The bumblebee package allows a program to be rendered on an
# dedicated video card by spawning an additional X11 server and
# streaming the results via VirtualGL or primus to the primary server.
# The package is rather chaotic; it's also quite recent.
# As it may change a lot, some of the hacks in this nix expression
# will hopefully not be needed in the future anymore.
# To test:
# 1. make sure that the 'bbswitch' kernel module is installed,
# 2. then run 'bumblebeed' as root
# 3. Then either 'optirun glxinfo' or 'primusrun glxinfo' as user.
#
# The glxinfo output should indicate the NVidia driver is being used
# and all expected extensions are supported.
#
# To use at startup, see hardware.bumblebee options.
