I've used libturbo-jpeg for a couple years with x2go after I first learned about it.
You might check your Distro... but at least for Ubuntu I believe libturbo-jpeg is the default installed by Ubuntu now.
*/NOTE: in the following - I _did have to_ install "libjpeg-turbo-progs" separately /*
On my Ubuntu 13.10 x64 system if I run Synaptic and search for "libturbo" I find:
*/Independent JPEG Group's JPEG runtime library (dependency package) /*
*//*
*/libjpeg8 dependency package, depending on libjpeg-turbo8./*
You might do the same on your Distro to find out what libjpeg is being used today.
