Synopsis

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.
