<para>
Modify the LCDd.conf file before you run LCDd. In this config file are
detailed instructions on how to configure the T6963 driver.
</para>

<para>
Then as usual, start LCDd with the correct config file:
</para>

<para>
E.g. <command>LCDd -c ./LCDd.conf</command>
</para>

<para>
If you want to override the driver selection in LCDd.conf then use:
</para>

<para>
<command>LCDd -c ./LCDd.conf -d T6963</command>
</para>

<para>
If you use this, the T6963 driver will read the options from the config
file anyway.
</para>
