--- Using the configure option relieves us of the patch and passing the path via the env var in many places. Also the env var may not be inherited when components like gdm spawn new sessions.

# 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.
