GnuPG 2.1.x changed the way the gpg-agent works, and that new approach no
longer requires (or even supports) the "start everything as a child of the
agent" scheme we've implemented in NixOS for older versions.
To configure the gpg-agent for your X session, add the following code to
~/.xsession or some other appropriate place that's sourced at start-up:
gpg-connect-agent /bye
GPG_TTY=$(tty)
export GPG_TTY
If you want to use gpg-agent for SSH, too, also add the settings
unset SSH_AGENT_PID
export SSH_AUTH_SOCK="${HOME}/.gnupg/S.gpg-agent.ssh"
and make sure that
enable-ssh-support
is included in your ~/.gnupg/gpg-agent.conf.
The gpg-agent(1) man page has more details about this subject, i.e. in the
"EXAMPLES" section.
- if xserver.tty and/or display are set to null, then don't specify
them, or the -logfile argument in the xserverArgs
- For lightdm, we set default tty and display to null and we determine
those at runtime based on arguments passed. This is necessary because
we run multiple X servers so they can't all be on the same display
Ctrl+Alt+Backspace is usually enabled by default under X, and is a
keyboard shortcut that forcefully kills the current X server. This can
lead to data loss by users if accidentally pressed. This commit
introduces a new option, services.xserver.enableCtrlAltBackspace, that
is *disabled* by default. If set to true, the previous behavior can be
restored.
A similar decision was made by the Ubuntu team, and is documented here:
https://wiki.ubuntu.com/XorgCtrlAltBackspace
This is needed by most window managers. Desktop environments
usually launch dbus-launch if a session hasn't been started yet
so this shouldn't hurt. The worst it can happen is that one
dbus session will be unused in case it's started twice.
The GDM change is backported from recent gdm.
The current options for the XServer produce a huge amount of log messages. The
server produces around 70-80 messages per minute. The most messages look like
this:
display-manager-start[1846]: GetModeLine - scrn: 0 clock: 75200
display-manager-start[1846]: GetModeLine - hdsp: 1366 hbeg: 1414 hend: 1478 httl: 1582
display-manager-start[1846]: vdsp: 768 vbeg: 772 vend: 779 vttl: 792 flags: 9
Since theses messages aren't very useful, I propose to remove the `-logverbose`
and `-verbose` options from the XServer arguments.
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.
Should bring most of the examples into a better consistency regarding
syntactic representation in the manual.
Thanks to @devhell for reporting.

Previously all card-specific stuff was scattered across xserver.nix
and opengl.nix, which is ugly. Now it can be kept together in a single
card-specific module. This required the addition of a few internal
options:
- services.xserver.drivers: A list of { name, driverName, modules,
libPath } sets.
- hardware.opengl.package: The OpenGL implementation. Note that there
can be only one OpenGL implementation at a time in a system
configuration (i.e. no dynamic detection).
- hardware.opengl.package32: The 32-bit OpenGL implementation.
Fixes#2379.
The new name was a misnomer because the values really are X11 video
drivers (e.g. ‘cirrus’ or ‘nvidia’), not OpenGL implementations. That
it's also used to set an OpenGL implementation for kmscon is just
confusing overloading.
This has some advantages:
* You get ssh-agent regardless of how you logged in. Previously it was
only started for X11 sessions.
* All sessions of a user share the same agent. So if you added a key
on tty1, it will also be available on tty2.
* Systemd will restart ssh-agent if it dies.
* $SSH_AUTH_SOCK now points to the /run/user/<uid> directory, which is
more secure than /tmp.
For bonus points, we should patch ssh-agent to support socket-based
activation...
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
With kmscon, it is now possible to have a system without X that still
needs the mesa setup in /run/opengl-driver

In most cases, this just meant changing kernelDev (now removed from
linuxPackagesFor) to kernel.dev. Some packages needed more work (though
whether that was because of my changes or because they were already
broken, I'm not sure). Specifics:
* psmouse-alps builds on 3.4 but not 3.10, as noted in the comments that
were already there
* blcr builds on 3.4 but not 3.10, as noted in comments that were
already there
* open-iscsi, ati-drivers, wis-go7007, and openafsClient don't build on
3.4 or 3.10 on this branch or on master, so they're marked broken
* A version-specific kernelHeaders package was added
The following packages were removed:
* atheros/madwifi is superceded by official ath*k modules
* aufs is no longer used by any of our kernels
* broadcom-sta v6 (which was already packaged) replaces broadcom-sta
* exmap has not been updated since 2011 and doesn't build
* iscis-target has not been updated since 2010 and doesn't build
* iwlwifi is part of mainline now and doesn't build
* nivida-x11-legacy-96 hasn't been updated since 2008 and doesn't build
Everything not specifically mentioned above builds successfully on 3.10.
I haven't yet tested on 3.4, but will before opening a pull request.

Previously logging in via SLiM more than once didn't work because SLiM
doesn't clean up its PAM session properly (that is, in a child rather
than in the parent). Thus the slim process becomes part of the user
session's cgroup, among other things. This patch causes SLiM to exit
after the session has finished, after which systemd will restart
display-manager.service.
FixesNixOS/nixops#137.
