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

62 ## Installation/removal
64 You can use the `autorandr.py` script as a stand-alone binary. If you'd like to
65 install it as a system-wide application, there is a Makefile included that also
66 places some configuration files in appropriate directories such that autorandr
67 is invoked automatically when a monitor is connected or removed, the system
68 wakes up from suspend, or a user logs into an X11 session. Run `make install`
69 as root to install it.
71 If you prefer to have a system wide install managed by your package manager,
74 * Use the [official Arch package](https://www.archlinux.org/packages/community/any/autorandr/).
75 * Use the [official Debian package](https://packages.debian.org/sid/x11/autorandr) on sid
76 * Use the [ebuild from zugaina](https://gpo.zugaina.org/x11-misc/autorandr) on Gentoo.
78 [nix package](https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/misc/autorandr.nix)
80 * Use the [SlackBuild](https://slackbuilds.org/repository/14.2/desktop/autorandr/) on Slackware.
81 * Use the automated nightlies generated by the
82 [openSUSE build service](https://build.opensuse.org/package/show/home:phillipberndt/autorandr)
83 for various distributions (RPM and DEB based).
84 * Use the [X binary package system](https://wiki.voidlinux.eu/XBPS)' on Void Linux
85 * Build a .deb-file from the source tree using `make deb`.
86 * Build a .rpm-file from the source tree using `make rpm`.
88 We appreciate packaging scripts for other distributions, please file a pull
89 request if you write one.
91 If you prefer `pip` over your package manager, you can install autorandr with:
93 sudo pip install "git+http://github.com/phillipberndt/autorandr#egg=autorandr"
97 sudo pip install autorandr
99 if you prefer to use a stable version.
103 Save your current display configuration and setup with:
105 autorandr --save mobile
107 Connect an additional display, configure your setup and save it:
109 autorandr --save docked
111 Now autorandr can detect which hardware setup is active:
117 To automatically reload your setup:
121 To manually load a profile:
123 $ autorandr --load <profile>
127 $ autorandr <profile>
129 autorandr tries to avoid reloading an identical configuration. To force the
132 $ autorandr --load <profile> --force
134 To prevent a profile from being loaded, place a script call _block_ in its
135 directory. The script is evaluated before the screen setup is inspected, and
136 in case of it returning a value of 0 the profile is skipped. This can be used
137 to query the status of a docking station you are about to leave.
139 If no suitable profile can be identified, the current configuration is kept.
140 To change this behaviour and switch to a fallback configuration, specify
141 `--default <profile>`. The system-wide installation of autorandr by default
142 calls autorandr with a parameter `--default default`. There are three special,
143 virtual configurations called `horizontal`, `vertical` and `common`. They
144 automatically generate a configuration that incorporates all screens
145 connected to the computer. You can symlink `default` to one of these
146 names in your configuration directory to have autorandr use any of them
147 as the default configuration without you having to change the system-wide
150 You can store default values for any option in an INI-file in
151 `~/.config/autorandr/settings.ini` in a section `config`. The most useful
152 candidate for doing that is `skip-options`, if you need it.
158 Three more scripts can be placed in the configuration directory
159 (as defined by the [XDG spec](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html),
160 usually `~/.config/autorandr` or `~/.autorandr` if you have an old installation
161 for user configuration and `/etc/xdg/autorandr` for system wide configuration):
163 - `postswitch` is executed *after* a mode switch has taken place. This can be
164 used to notify window managers or other applications about the switch.
165 - `preswitch` is executed *before* a mode switch takes place.
166 - `postsave` is executed after a profile was stored or altered.
167 - `predetect` is executed before autorandr attempts to run xrandr.
169 These scripts must be executable and can be placed directly in the configuration
170 directory, where they will always be executed, or in the profile subdirectories,
171 where they will only be executed on changes regarding that specific profile.
173 Instead (or in addition) to these scripts, you can also place as many executable
174 files as you like in subdirectories called `script_name.d` (e.g. `postswitch.d`).
176 If a script with the same name occurs multiple times, user configuration
177 takes precedence over system configuration (as specified by the
178 [XDG spec](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html))
179 and profile configuration over general configuration.
181 As a concrete example, suppose you have the files
183 - `/etc/xdg/autorandr/postswitch`
184 - `~/.config/autorandr/postswitch`
185 - `~/.config/autorandr/postswitch.d/notify-herbstluftwm`
186 - `~/.config/autorandr/docked/postswitch`
188 and switch from `mobile` to `docked`. Then
189 `~/.config/autorandr/docked/postswitch` is executed, since the profile specific
190 configuration takes precedence, and
191 `~/.config/autorandr/postswitch.d/notify-herbstluftwm` is executed, since
192 it has a unique name.
194 If you switch back from `docked` to `mobile`, `~/.config/autorandr/postswitch`
195 is executed instead of the `docked` specific `postswitch`.
197 If you experience issues with xrandr being executed too early after connecting
198 a new monitor, then you can use a `predetect` script to delay the execution.
199 Write e.g. `sleep 1` into that file to make autorandr wait a second before
204 Some of autorandr's state is exposed as environment variables
205 prefixed with `AUTORANDR_`, such as:
206 - `AUTORANDR_CURRENT_PROFILE`
207 - `AUTORANDR_CURRENT_PROFILES`
208 - `AUTORANDR_PROFILE_FOLDER`
209 - `AUTORANDR_MONITORS`
211 with the intention that they can be used within the hook scripts.
213 For instance, you might display which profile has just been activated by
214 including the following in a `postswitch` script:
216 notify-send -i display "Display profile" "$AUTORANDR_CURRENT_PROFILE"
219 The one kink is that during `preswitch`, `AUTORANDR_CURRENT_PROFILE` is
220 reporting the *upcoming* profile rather than the *current* one.
222 ### Wildcard EDID matching
224 The EDID strings in the `~/.config/autorandr/*/setup` files may contain an
225 asterisk to enable wildcard matching: Such EDIDs are matched against connected
226 monitors using the usual file name globbing rules. This can be used to create
227 profiles matching multiple (or any) monitors.
229 ### udev triggers with NVidia cards
231 In order for `udev` to detect `drm` events from the native NVidia driver, the
232 kernel parameter `nvidia-drm.modeset` must be set to 1. For example, add a file
233 `/etc/modprobe.d/nvidia-drm-modeset.conf`:
236 options nvidia_drm modeset=1
