Vladimír Čunát e4436ad841 FONTCONFIG_FILE: remove setters to /etc/fonts/fonts.conf
Any reasonably new version of fontconfig does search that path by default,
and setting this globally causes problems, as 2.10 and 2.11 need
incompatible configs.

Tested: slim+xfce desktop, chrootenv-ed steam.
I have no idea why we were setting the global variable;
e.g., neither Fedora nor Ubuntu does that.

# 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 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: make sure that the 'bbswitch' kernel module is installed,
# then run 'bumblebeed' as root and 'optirun glxgears' as user.
# To use at startup, see hardware.bumblebee options.
# This nix expression supports for now only the native nvidia driver.
# It should not be hard to generalize this approach to support the
# nouveau driver as well (parameterize commonEnv over the module
# package, and parameterize the two wrappers as well)
