DE1-SoC No /dev/fpga0 device on LXDE or Ubuntu

I know that it's an old topic but i had the same issue and i found out something very interesting. For the new Kernel (say 4.4 for example) a "fpgamanager" was introduced and it changed the way you should send the rbf files to the fpga.

Now you need to make a devicetree overlay in order to load the rbf file, but the fpgamanager will stop the bridges and do all the work for you.

I'm attempting to write a simple tutorial to the process but i'm not that good at writing an i'm not an expert on the subjec, so i'm bound to be mistaken at some things, but i know for sure that i can program de fpga. So i'll post the link here once i finish the tutorial.
