74 -h, --help get this small help
75 -c, --change automatically load the first detected profile
76 -d, --default <profile> make profile <profile> the default profile
77 -l, --load <profile> load profile <profile>
78 -s, --save <profile> save your current setup to profile <profile>
79 -r, --remove <profile> remove profile <profile>
80 --batch run autorandr for all users with active X11 sessions
81 --current only list current (active) configuration(s)
82 --config dump your current xrandr setup
83 --debug enable verbose output
84 --detected only list detected (available) configuration(s)
85 --dry-run don't change anything, only print the xrandr commands
86 --fingerprint fingerprint your current hardware setup
87 --force force (re)loading of a profile / overwrite exiting files
88 --list list configurations
89 --skip-options <option> comma separated list of xrandr arguments (e.g. "gamma")
90 to skip both in detecting changes and applying a profile
91 --version show version information and exit
93 If no suitable profile can be identified, the current configuration is kept.
94 To change this behaviour and switch to a fallback configuration, specify
97 autorandr supports a set of per-profile and global hooks. See the documentation
