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