Added configurations to `bumblebee` package to easy multiple monitors on Optimus
machines.
The behaviour of the default `bumblebee` package hasn't change, so this change
is backwards compatible. Users who want to connect a monitor to their discrete
card should use the package `bumblebee_display` instead.
Also added new configuration option to nixos bumblebee module:
```
hardware.bumblebee.connectDisplay = true
```
will enable the new configuration, but the default is still false.
Using primusrun will work as expected in a multilib environment. Even if the initial program
executes a antoehr program of the another architecture. Assuming the program does not modify
LD_LIBRARY_PATH inappropriately.
This does not update virtualgl for seemless multilib. I was unable to get a mixed 64/32 bit
environment to work with VirtualGL. The mechanism VirtualGL uses to inject the fake GL library would
fail if both 32bit and 64 bit libraries were in the environment. Instead the bumblebee package
creates a optirun32 executable that can be used to run a 32bit executable with optimus on a 64 bit
host. This is not created if the host is 32bit.
For my usage, gaming under wine, the primusrun executable works as expected regardless of
32bit/64bit.
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.
(My OCD kicked in today...)
Remove repeated package names, capitalize first word, remove trailing
periods and move overlong descriptions to longDescription.
I also simplified some descriptions as well, when they were particularly
long or technical, often based on Arch Linux' package descriptions.
I've tried to stay away from generated expressions (and I think I
succeeded).
Some specifics worth mentioning:
* cron, has "Vixie Cron" in its description. The "Vixie" part is not
mentioned anywhere else. I kept it in a parenthesis at the end of the
description.
* ctags description started with "Exuberant Ctags ...", and the
"exuberant" part is not mentioned elsewhere. Kept it in a parenthesis
at the end of description.
* nix has the description "The Nix Deployment System". Since that
doesn't really say much what it is/does (especially after removing
the package name!), I changed that to "Powerful package manager that
makes package management reliable and reproducible" (borrowed from
nixos.org).
* Tons of "GNU Foo, Foo is a [the important bits]" descriptions
is changed to just [the important bits]. If the package name doesn't
contain GNU I don't think it's needed to say it in the description
either.
Version 0.11.6 was the latest version that I was able to get building
and running on NixOS. Unfortunately my previous commit for 0.12.5 was
an error and incomplete.
* Bump bumblebee to 3.2.1
* Remove config.patch - options it added can be passed to ./configure now
* Remove the provided xorg.conf
Provided xorg.conf was causing problems for some users,
and Bumblebee provides its own default configuration anyway.
* Make secondary X11 log to /var/log/X.bumblebee.log
* Add a module for bumblebee
