autorandr 1.15.post1

autorandr
Automatically select a display configuration based on connected devices
Branch information
This is a compatible Python rewrite of
wertarbyte/autorandr. Contributions
for bash-completion, fd.o/XDG autostart, Nitrogen, pm-utils, and systemd can be
found under contrib.
The original wertarbyte/autorandr
tree is unmaintained, with lots of open pull requests and issues. I forked it
and merged what I thought were the most important changes. If you are searching
for that version, see the legacy branch.
Note that the Python version is better suited for non-standard configurations,
like if you use --transform or --reflect. If you use auto-disper, you
have to use the bash version, as there is no disper support in the Python
version (yet). Both versions use a compatible configuration file format, so
you can, to some extent, switch between them. I will maintain the legacy
branch until @wertarbyte finds the time to maintain his branch again.
If you are interested in why there are two versions around, see
#7,
#8 and
especially
#12
if you are unhappy with this version and would like to contribute to the bash
version.

Installation/removal
You can use the autorandr.py script as a stand-alone binary. If you'd like to
install it as a system-wide application, there is a Makefile included that also
places some configuration files in appropriate directories such that autorandr
is invoked automatically when a monitor is connected or removed, the system
wakes up from suspend, or a user logs into an X11 session. Run make install
as root to install it.
If you prefer to have a system wide install managed by your package manager,
you can

Use the official Arch package.
Use the official Debian package on sid
Use the FreeBSD Ports Collection on FreeBSD.
Use the official Gentoo package.
Use the
nix package
on NixOS.
Use the
guix package
on Guix.
Use the SlackBuild on Slackware.
Use the automated nightlies generated by the
openSUSE build service
for various distributions (RPM and DEB based).
Use the X binary package system' on Void Linux
Build a .deb-file from the source tree using make deb.
Build a .rpm-file from the source tree using make rpm.

We appreciate packaging scripts for other distributions, please file a pull
request if you write one.
If you prefer pip over your package manager, you can install autorandr with:
sudo pip install "git+http://github.com/phillipberndt/autorandr#egg=autorandr"

or simply
sudo pip install autorandr

if you prefer to use a stable version.
How to use
Save your current display configuration and setup with:
autorandr --save mobile

Connect an additional display, configure your setup and save it:
autorandr --save docked

Now autorandr can detect which hardware setup is active:
$ autorandr
mobile
docked (detected)

To automatically reload your setup:
$ autorandr --change

To manually load a profile:
$ autorandr --load <profile>

or simply:
$ autorandr <profile>

autorandr tries to avoid reloading an identical configuration. To force the
(re)configuration:
$ autorandr --load <profile> --force

To prevent a profile from being loaded, place a script call block in its
directory. The script is evaluated before the screen setup is inspected, and
in case of it returning a value of 0 the profile is skipped. This can be used
to query the status of a docking station you are about to leave.
If no suitable profile can be identified, the current configuration is kept.
To change this behaviour and switch to a fallback configuration, specify
--default <profile>. The system-wide installation of autorandr by default
calls autorandr with a parameter --default default. There are three special,
virtual configurations called horizontal, vertical and common. They
automatically generate a configuration that incorporates all screens
connected to the computer. You can symlink default to one of these
names in your configuration directory to have autorandr use any of them
as the default configuration without you having to change the system-wide
configuration.
You can store default values for any option in an INI-file located at
~/.config/autorandr/settings.ini. In a config section, you may place any
default values in the form option-name=option-argument.
A common and effective use of this is to specify default skip-options, for
instance skipping the gamma setting if using
redshift as a daemon. To implement
the equivalent of --skip-options gamma, your settings.ini file should look
like this:
[config]
skip-options=gamma

Advanced usage
Hook scripts
Three more scripts can be placed in the configuration directory
(as defined by the XDG spec,
usually ~/.config/autorandr or ~/.autorandr if you have an old installation
for user configuration and /etc/xdg/autorandr for system wide configuration):

postswitch is executed after a mode switch has taken place. This can be
used to notify window managers or other applications about the switch.
preswitch is executed before a mode switch takes place.
postsave is executed after a profile was stored or altered.
predetect is executed before autorandr attempts to run xrandr.

These scripts must be executable and can be placed directly in the configuration
directory, where they will always be executed, or in the profile subdirectories,
where they will only be executed on changes regarding that specific profile.
Instead (or in addition) to these scripts, you can also place as many executable
files as you like in subdirectories called script_name.d (e.g. postswitch.d).
The order of execution of scripts in these directories is by file name, you can
force a certain ordering by naming them 10-wallpaper, 20-restart-wm, etc.
If a script with the same name occurs multiple times, user configuration
takes precedence over system configuration (as specified by the
XDG spec)
and profile configuration over general configuration.
As a concrete example, suppose you have the files

/etc/xdg/autorandr/postswitch
~/.config/autorandr/postswitch
~/.config/autorandr/postswitch.d/notify-herbstluftwm
~/.config/autorandr/docked/postswitch

and switch from mobile to docked. Then
~/.config/autorandr/docked/postswitch is executed, since the profile specific
configuration takes precedence, and
~/.config/autorandr/postswitch.d/notify-herbstluftwm is executed, since
it has a unique name.
If you switch back from docked to mobile, ~/.config/autorandr/postswitch
is executed instead of the docked specific postswitch.
If you experience issues with xrandr being executed too early after connecting
a new monitor, then you can use a predetect script to delay the execution.
Write e.g. sleep 1 into that file to make autorandr wait a second before
running xrandr.
Variables
Some of autorandr's state is exposed as environment variables
prefixed with AUTORANDR_, such as:

AUTORANDR_CURRENT_PROFILE
AUTORANDR_CURRENT_PROFILES
AUTORANDR_PROFILE_FOLDER
AUTORANDR_MONITORS

with the intention that they can be used within the hook scripts.
For instance, you might display which profile has just been activated by
including the following in a postswitch script:
notify-send -i display "Display profile" "$AUTORANDR_CURRENT_PROFILE"

The one kink is that during preswitch, AUTORANDR_CURRENT_PROFILE is
reporting the upcoming profile rather than the current one.
Wildcard EDID matching
The EDID strings in the ~/.config/autorandr/*/setup files may contain an
asterisk to enable wildcard matching: Such EDIDs are matched against connected
monitors using the usual file name globbing rules. This can be used to create
profiles matching multiple (or any) monitors.
udev triggers with NVidia cards
In order for udev to detect drm events from the native NVidia driver, the
kernel parameter nvidia-drm.modeset must be set to 1. For example, add a file
/etc/modprobe.d/nvidia-drm-modeset.conf:
options nvidia_drm modeset=1

Wayland
Before running autorandr will check the environment for the WAYLAND_DISPLAY
variable to check if the program is running in a Wayland session. This is to
avoid issues between usage of xrandr in Wayland environments.
If you need to run autorandr in a Wayland environment, one workaround is to
unset the WAYLAND_DISPLAY variable before running the program, such as:
WAYLAND_DISPLAY= autorandr
