Xrandr
is used to set the size, orientation and/or reflection of the outputs for a
screen. It can also set the screen size.
If invoked without any option, it will dump the state of the outputs,
showing the existing modes for each of them, with a '+' after the preferred
mode and a '*' after the current mode.
There are a few global options. Other options modify the last output that is
specified in earlier parameters in the command line. Multiple outputs may
be modified at the same time by passing mutiple --output options followed
immediately by their corresponding modifying options.
- --help
-
Print out a summary of the usage and exit.
- -v
-
Print out the RandR version reported by the X server and exit.
- --verbose
-
causes xrandr to be more verbose. When used with -q (or without other
options), xrandr will display more information about the server state. When
used along with options that reconfigure the system, progress will be
reported while executing the configuration changes.
- -q
-
When this option is present, or when no configuration changes are requested,
xrandr will display the current state of the system.
- -screen snum
-
This option selects which screen to manipulate. Note this refers to the X
screen abstraction, not the monitor (or output).
