52 Usage: autorandr [options]
54 -h, --help get this small help
55 -c, --change reload current setup
56 -s, --save <profile> save your current setup to profile <profile>
57 -l, --load <profile> load profile <profile>
58 -d, --default <profile> make profile <profile> the default profile
59 --skip-options <option> comma separated list of xrandr arguments (e.g. "gamma")
60 to skip both in detecting changes and applying a profile
61 --force force (re)loading of a profile
62 --fingerprint fingerprint your current hardware setup
63 --config dump your current xrandr setup
64 --dry-run don't change anything, only print the xrandr commands
66 To prevent a profile from being loaded, place a script call "block" in its
67 directory. The script is evaluated before the screen setup is inspected, and
68 in case of it returning a value of 0 the profile is skipped. This can be used
69 to query the status of a docking station you are about to leave.
71 If no suitable profile can be identified, the current configuration is kept.
72 To change this behaviour and switch to a fallback configuration, specify
75 Another script called "postswitch" can be placed in the directory
76 ~/.config/autorandr (or ~/.autorandr if you have an old installation) as well
77 as in any profile directories: The scripts are executed after a mode switch
78 has taken place and can notify window managers.
80 The following virtual configurations are available:
