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