Automatically select a display configuration based on connected devices
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
Note that the Python version is better suited for non-standard configurations,
like if you use
--reflect. If you use
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
branch until @wertarbyte finds the time to maintain his branch again.

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
as root to install it.
If you prefer to have a system wide install managed by your package manager, you can
- Use the aur package on Arch
- Use the official Debian package on sid
- Use the ebuild from zugaina on Gentoo.
- Use the nix package on NixOS.
- Use the automated nightlies generated by the openSUSE build service for various distributions (RPM and DEB based).
- Build a .deb-file from the source tree using
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"
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>
$ 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

connected to the computer. You can symlink
default to one of these

You can store default values for any option in an INI-file in
~/.config/autorandr/settings.ini in a section

candidate for doing that is
skip-options, if you need it.
Three more scripts can be placed in the configuration directory (as

~/.autorandr if you have an old installation
for user configuration and
/etc/xdg/autorandr for system wide configuration):
postswitchis executed after a mode switch has taken place. This can be used to notify window managers or other applications about the switch.
preswitchis executed before a mode switch takes place.
postsaveis executed after a profile was stored or altered.
predetectis 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
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

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.
