No, that's not true. Basically LCD4Linux could run as any user. But
there's a security check, it refuses to work if the config file (usually
/etc/lcd4linux.conf) does not belong to the current user, and/or group
or others have access to it.

So if you want to run lcd4linux as 'apache', make shure that
/etc/lcd4linux.conf is owned by apache, too, and that it's permissions
are 0600. Depending on your display, the user apache must have access to
the LCD device, too.


HTH, Michael
