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