Thank you for this tutorial. After Microsoft decided to stop my little Miner by an update of Win10 i installed ubuntu with AMD RX drivers as described above. Up to now it works fine without any reboot after installation of the driver and mining software.
The only thing i have had to do extra in windows was to flash the BIOS of the VideoCard back to the original Version. Else X11 and the miner won´t work. - Unfortunately the AMD Linux driver is same small-minded in overclocking than in windows.
