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