--- Comment #6 from Antonio Chirizzi antonio.chirizzi@gmail.com --- Hello fin4478, thanks for the suggestion. I have tried the latest Manjaro Xfce, it's able to boot but it's not able to start the graphics environment. I have seen that for the Ryzen 7 2700U (my CPU) there are a few people who are experiencing the same problem iwth Manjaro. Moreover it starts up with kernel 4.14, which is too old for the Ryzen I think.
Going back to your comment on Linux Mint 19 and the old software, is it possible in your opinion that the old software is causing a fault in the Kernel for the amdgpu?
