"Enable HDR tone mapping" - Synology NAS

@herman_munster

Did you see my Synology - DSM 7 (version 2.0) - Docker How-To?

I show the steps you need take to get the UID/GID for “PlexMediaServer”
then how to setup the command line docker to access /dev/dri since it’s blocked in DSM 7 GUI

It’s not at all elegant but gets the job done
