TALER-MDB-DISPLAY(1)

NAME
taler-mdb-display - turns the framebuffer backlight on or off

SYNOPSIS

taler-mdb-display [-c FILENAME] [-h] [-i | --backlight-invert] [-L LOGLEVEL | --log=LOGLEVEL] [-l FILENAME | --logfile=FILENAME] [-v | --version]

DESCRIPTION

taler-mdb-display is a command-line tool that simply toggles the backlight setting. Depending on the hardware, this -i may be used to turn the light on or off. The opposite effect can then be achieved without the -i option.

Its options are as follows:

-c FILENAME | --config=‌FILENAME
    Use the configuration and other resources for the command to operate from FILENAME.

-i | --backlight-invert
    Invert the bit for turning on/off the backlight (without the option, the tool will do the opposite).

-h | --help
    Print short help on options.

-L LOGLEVEL | --log=LOGLEVEL
    Configure logging to use LOGLEVEL.

-l FILENAME | --logfile=FILENAME
    Configure logging to write logs to FILENAME.

-v | –version
    Print version information.
