Usage: autorandr [options]
-h, --help get this small help
--c, --change reload current setup
--s, --save <profile> save your current setup to profile <profile>
--l, --load <profile> load profile <profile>
+-c, --change automatically load the first detected profile
-d, --default <profile> make profile <profile> the default profile
---force force (re)loading of a profile
---fingerprint fingerprint your current hardware setup
+-l, --load <profile> load profile <profile>
+-s, --save <profile> save your current setup to profile <profile>
+-r, --remove <profile> remove profile <profile>
+--batch run autorandr for all users with active X11 sessions
+--current only list current (active) configuration(s)
--config dump your current xrandr setup
+--debug enable verbose output
+--detected only list detected (available) configuration(s)
--dry-run don't change anything, only print the xrandr commands
-
- 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.
+--fingerprint fingerprint your current hardware setup
+--force force (re)loading of a profile
+--skip-options <option> comma separated list of xrandr arguments (e.g. "gamma")
+ to skip both in detecting changes and applying a profile
+--version show version information and exit
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>.
- Another script called "postswitch" can be placed in the directory
- ~/.config/autorandr (or ~/.autorandr if you have an old installation) as well
- as in any profile directories: The scripts are executed after a mode switch
- has taken place and can notify window managers.
+ autorandr supports a set of per-profile and global hooks. See the documentation
+ for details.
The following virtual configurations are available:
