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