For the open driver, the `nvidia-uvm` module does not auto-load after
`nvidia`, which makes CUDA not work.
In this case, we need to add it to `boot.kernelModules` for it to work
again.
In my experience this is required to get Plasma 6 Wayland to work on
my GTX 1080 with the proprietary driver. Otherwise, I get errors in my
`journalctl --user` about "MESA-LOADER: failed to open simpledrm" (among
many other things) and Plasma just presents a black screen with a cursor
and nothing else.
I discovered this by searching the aforementioned error and found
[this Arch Linux forum post][0] and some further clicking around led
me to [this section on the ArchWiki][1], which is where I got the
`versionAtLeast` value from.
Tested with `nvidia-x11-555.58-6.9.7`.

I am the singular maintainer for these packages. They are difficult to
maintain and are going to start to bitrot pretty much as soon as BMD
releases new software versions. Therefore, I am not only removing myself
as the maintainer but dropping them entirely.
- rename hardware.opengl to hardware.graphics
- remove hardware.opengl.driSupport, which does nothing
- remove hardware.opengl.setLdLibraryPath, which should never be done
- rename hardware.opengl.driSupport32Bit to hardware.graphics.enable32Bit
- lost of small docs / formatting cleanups
This library does not actually need to match the Nvidia driver version,
so we do not need to make it available impurely.
This reverts the following commits.

I want to use the final symlinked package in system.checks and need to
access that somehow. Instead of adding a new option, we might as well
convert tmpfiles to the new structure.
Commit a52e27d4f6
changed the `ensurePrinter` mechanism such that it uses
`lib.cli.toGNUCommandLineShell` to assemble the
`lpadmin` command line that creates the required printer.
Before that commit, the command line contained
single quotes (')to protect certain options from being
(mis-)interpreted by the shell.
The new mechanism no longer needs those quotes as
`lib.cli.toGNUCommandLineShell` takes care of quoting/escaping.
Unfortunatelly, the commit missed the
quotes around the `-o` command line part.
`lib.cli.toGNUCommandLineShell` now properly escapes
those quotes, thereby including them in the effective
command line arguments that are passed to `lpadmin`.
The result is that no option is applied anymore.
The commit at hand simply removes the superfluous quotes.
With this change, options are again properly applied as before.
these changes were generated with nixq 0.0.2, by running
nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix
two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.
Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.
Provide a module for installing ryzen_smu, a Linux kernel driver
that exposes access to the SMU (System Management Unit) for
certain AMD Ryzen Processors.
Installs monitor_cpu, a userspace tool for viewing info.
Using fork of original to match ryzen_monitor_ng, a more advanced
userspace tool for accessing the SMU via this kernel module,
planned for a later commit.
The NVIDIA X driver uses a UNIX domain socket to pass information to
other driver components. If unable to connect to this socket, some
driver features, such as G-Sync, may not work correctly. The socket will
be bound to a file with a name unique to the X server instance created
in the directory specified by this option. Note that on Linux, an
additional abstract socket (not associated with a file) will also be
created, with this pathname socket serving as a fallback if connecting
to the abstract socket fails.
The default, which was in effect prior to this change, was `/var/run`.
The effect of not setting this option was that GDM X sessions
(and other non-root sessions) would see this warning in the log files:
```
(WW) NVIDIA: Failed to bind sideband socket to
(WW) NVIDIA: '/var/run/nvidia-xdriver-b4f69129' Permission denied
```
I don't see any security implications of turning this on universally,
since there already was an abstract socket created according to the
docs.
