mate-control-center depends on mate-settings-daemon, but the later needs
gsettings schemas provided by the former. To fix this the gsettings schema
path from mate-control-center is added to XDG_DATA_DIRS at session
startup.
Instead of polluting the environment with environment variables which
are inherited by processes spawned from awesome, use the command line
argument "--search" to add things to the search path.
cc #33169
(originally from f9415cb621)
feh is used to set background image for desktop managers that do not
support it directly, however there is no need to include it in PATH.
Fixes#17450.
Now there are separate `xfce4.xfce4mixer_pulse` and `xfce4.xfcevolumed_pulse` attributes for PulseAudio versions of these packages, instead of relying on Nixpkgs option. Mind that xfce4-volumed and xfce4-volumed-pulse are actually two separate programs without much overlap.
There are security fixes in multiple packages /cc #32117,
so I'm merging a little earlier, with a few thousand jobs
still not finished on Hydra for x86_64-darwin and aarch64-linux.
For some reason, the GNOME 3.26 update broke the overrides. It turns
out the overrides now need to come before the overridden schemas in the
XDG_DATA_DIRS variable. This is not possible in general due to applications
prefixing the variable (e.g. in wrapGAppsHook).
To fix this, a new environment variable NIX_GSETTINGS_OVERRIDES_DIR
was introduced. It has greater priority than XDG_DATA_DIRS but lower
than GSETTINGS_SCHEMA_DIR. A separate variable was chosen in order not
to block the built-in one for users.
With libinput used for keyboard, base rules produce incorrect keyboard
layouts. We are removing the option as recommended in the XKB configuration
guide [1] to let X server choose the ruleset. It looks like it chooses
evdev rules which seem to work for some reason

This reverts commit 93c54acf97.
This reopens#30517 @nbp @Ma27
Breaking people's config for this is hardly reasonable as is. If it
absolutely cannot be avoided, at the very least, we need to provide
clear instructions on what people need to upgrade in their config. I
actually had to bisect to the commit, to even find out what property I
should change or define, as the error message was useless. It didn't
even mention a property name.
Discussion on the PR seems to be ongoing, so I'm reverting this, so we
don't break people's systems on unstable.
