Hi!

Did as you suggested:

	# apt purge firmware-amd-graphics
	# rm -rf /lib/firmware/amdgpu
	# apt install firmware-amd-graphics

Then I copied file by file, restarting the system between each copy until I got a working graphical environment.

The files needed for me are:

	pitcairn_mc.bin
	pitcairn_smc.bin
	pitcairn_pfp.bin
	pitcairn_me.bin
	pitcairn_ce.bin
	pitcairn_rlc.bin

Would you like me to test anything else?


Regards,
Felipe.
