3 Automatically select a display configuration based on connected devices
7 This is a compatible Python rewrite of
8 [wertarbyte/autorandr](https://github.com/wertarbyte/autorandr). Contributions
9 for bash-completion, fd.o/XDG autostart, Nitrogen, pm-utils, and systemd can be
10 found under [contrib](contrib/).
12 The original [wertarbyte/autorandr](https://github.com/wertarbyte/autorandr)
13 tree is unmaintained, with lots of open pull requests and issues. I forked it
14 and merged what I thought were the most important changes. If you are searching
15 for that version, see the [`legacy` branch](https://github.com/phillipberndt/autorandr/tree/legacy).
16 Note that the Python version is better suited for non-standard configurations,
17 like if you use `--transform` or `--reflect`. If you use `auto-disper`, you
18 have to use the bash version, as there is no disper support in the Python
19 version (yet). Both versions use a compatible configuration file format, so
20 you can, to some extent, switch between them. I will maintain the `legacy`
21 branch until @wertarbyte finds the time to maintain his branch again.
23 If you are interested in why there are two versions around, see
24 [#7](https://github.com/phillipberndt/autorandr/issues/7),
25 [#8](https://github.com/phillipberndt/autorandr/issues/8) and

61 ## Installation/removal
63 You can use the `autorandr.py` script as a stand-alone binary. If you'd like to
64 install it as a system-wide application, there is a Makefile included that also
65 places some configuration files in appropriate directories such that autorandr
66 is invoked automatically when a monitor is connected or removed, the system
67 wakes up from suspend, or a user logs into an X11 session. Run `make install`
68 as root to install it.
70 If you prefer to have a system wide install managed by your package manager,
73 * Use the [official Arch package](https://www.archlinux.org/packages/community/any/autorandr/).
74 * Use the [official Debian package](https://packages.debian.org/sid/x11/autorandr) on sid
75 * Use the [ebuild from zugaina](https://gpo.zugaina.org/x11-misc/autorandr) on Gentoo.
77 [nix package](https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/misc/autorandr.nix)
79 * Use the automated nightlies generated by the
80 [openSUSE build service](https://build.opensuse.org/package/show/home:phillipberndt/autorandr)
81 for various distributions (RPM and DEB based).
82 * Use the [X binary package system](https://wiki.voidlinux.eu/XBPS)' on Void Linux
83 * Build a .deb-file from the source tree using `make deb`.
85 We appreciate packaging scripts for other distributions, please file a pull
86 request if you write one.
88 If you prefer `pip` over your package manager, you can install autorandr with:
90 sudo pip install "git+http://github.com/phillipberndt/autorandr#egg=autorandr"
94 sudo pip install autorandr
96 if you prefer to use a stable version.
100 Save your current display configuration and setup with:
102 autorandr --save mobile
104 Connect an additional display, configure your setup and save it:
106 autorandr --save docked
108 Now autorandr can detect which hardware setup is active:
114 To automatically reload your setup:
118 To manually load a profile:
120 $ autorandr --load <profile>
124 $ autorandr <profile>
126 autorandr tries to avoid reloading an identical configuration. To force the
129 $ autorandr --load <profile> --force
131 To prevent a profile from being loaded, place a script call _block_ in its
132 directory. The script is evaluated before the screen setup is inspected, and
133 in case of it returning a value of 0 the profile is skipped. This can be used
134 to query the status of a docking station you are about to leave.
136 If no suitable profile can be identified, the current configuration is kept.
137 To change this behaviour and switch to a fallback configuration, specify
138 `--default <profile>`. The system-wide installation of autorandr by default
139 calls autorandr with a parameter `--default default`. There are three special,
140 virtual configurations called `horizontal`, `vertical` and `common`. They
141 automatically generate a configuration that incorporates all screens
142 connected to the computer. You can symlink `default` to one of these
143 names in your configuration directory to have autorandr use any of them
144 as the default configuration without you having to change the system-wide
147 You can store default values for any option in an INI-file in
148 `~/.config/autorandr/settings.ini` in a section `config`. The most useful
149 candidate for doing that is `skip-options`, if you need it.
155 Three more scripts can be placed in the configuration directory (as
156 (as defined by the [XDG spec](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html),
157 usually `~/.config/autorandr` or `~/.autorandr` if you have an old installation
158 for user configuration and `/etc/xdg/autorandr` for system wide configuration):
160 - `postswitch` is executed *after* a mode switch has taken place. This can be
161 used to notify window managers or other applications about the switch.
162 - `preswitch` is executed *before* a mode switch takes place.
163 - `postsave` is executed after a profile was stored or altered.
164 - `predetect` is executed before autorandr attempts to run xrandr.
166 These scripts must be executable and can be placed directly in the configuration
167 directory, where they will always be executed, or in the profile subdirectories,
168 where they will only be executed on changes regarding that specific profile.
170 Instead (or in addition) to these scripts, you can also place as many executable
171 files as you like in subdirectories called `script_name.d` (e.g. `postswitch.d`).
173 If a script with the same name occurs multiple times, user configuration
174 takes precedence over system configuration (as specified by the
175 [XDG spec](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html))
176 and profile configuration over general configuration.
178 As a concrete example, suppose you have the files
180 - `/etc/xdg/autorandr/postswitch`
181 - `~/.config/autorandr/postswitch`
182 - `~/.config/autorandr/postswitch.d/notify-herbstluftwm`
183 - `~/.config/autorandr/docked/postswitch`
185 and switch from `mobile` to `docked`. Then
186 `~/.config/autorandr/docked/postswitch` is executed, since the profile specific
187 configuration takes precedence, and
188 `~/.config/autorandr/postswitch.d/notify-herbstluftwm` is executed, since
189 it has a unique name.
191 If you switch back from `docked` to `mobile`, `~/.config/autorandr/postswitch`
192 is executed instead of the `mobile` specific `postswitch`.
194 In these scripts, some of autorandr's state is exposed as environment variables
195 prefixed with `AUTORANDR_`, such as:
196 - `AUTORANDR_CURRENT_PROFILE`
197 - `AUTORANDR_CURRENT_PROFILES`
198 - `AUTORANDR_PROFILE_FOLDER`
199 - `AUTORANDR_MONITORS`
201 If you experience issues with xrandr being executed too early after connecting
202 a new monitor, then you can use a `predetect` script to delay the execution.
203 Write e.g. `sleep 1` into that file to make autorandr wait a second before
206 ### Wildcard EDID matching
208 The EDID strings in the `~/.config/autorandr/*/setup` files may contain an
209 asterisk to enable wildcard matching: Such EDIDs are matched against connected
210 monitors using the usual file name globbing rules. This can be used to create
211 profiles matching multiple (or any) monitors.
