Hi guys,

still being fairly new to Linux i encountered the following problem:

Recently i built a rig with a Ryzen 7 1700x and AMD GPU´s and then installed nvOC 19-2.0 Community.

Did not work at all, always got stuck in a login loop and the miner1 password didn´t work, the rig stayed in the login loop.

So obviously i started searching the web and found several threads with exactly the same problem, not for nvOC but Ubuntu 16.04. And there were some solutions which helped others like reassign the read write permissions, renewing .Xauthority and other solutions but none of these worked on my rig, it stayed in the login loop no matter what i did. I used a freshly imaged nvOC 19-2.0 with no changes whatsoever.
I could ctrl+alt+f1 into a tty and login but i could not get nvOC to start and run a miner.

So i figured i just try a different combination and changed the motherboard and now it gets weired. After changing the mobo the same thing happened i was stuck in the login loop so i started to change everything. I tried several motherboard´s, switched memory sticks, used Nvidia GPU´s as well as AMD GPU´s, put nvOC on an USB stick as well as on a harddisk but nothing worked for me in combination with a Ryzen processor. I also tried a Ryzen 3 and a Ryzen 5. Using a windows setup all these combinations worked just fine but not with nvOC.

The second i put a Ryzen processor into any one rig and install nvOC i always get stuck in a login loop.

So is there anybody out there successfully mining with a Ryzen processor and nvOC?
Was anybody stuck in the login loop on nvOC and successfully resolved this matter and how?

Sorry guy´s i am lost here, need some help i can´t use nvOC with a Ryzen processor.

You are using AMD GPU on nvOC?
You should use rxOC for AMD and cant use mix of Nvidia and AMD on nvOC and rxOC

Let me clear it up. No, i was not mixing AMD and Nvidia gpu´s in one rig, instead i built several rigs either using all AMD or all Nvidia.
In fact, after figuring out that it has something to do with the Ryzen cpu i built a rig with a Ryzen 7 1700x and a single AMD gpu then installed nvOC 19-2.0 and got stuck in the login loop. I rebuilt the rig, this time using a single nvidia card alongside the Ryzen 7 1700x and again was stuck in the login loop. To further explain, the Ryzen 7 doesn´t have a builtin gpu, so in order to get anything on the screen you have to use at least a single external gpu.

That is why i was asking if somebody actually is mining succesfully using nvOC in combination with a Ryzen cpu? I can´t get passed the login loop using any Ryzen cpu and nvOC. And since i don´t know enough about Linux i can´t resolve the login loop by myself.

Don't bother with Ryzen CPU on the current nvoc which is based on Ubuntu 16.04 which runs on linux kernel 4.4. That kernel doesn't support Ryzen.
You could upgrade kernel on ubuntu 16.04 to 4.10 which gives partial support for Ryzen but not stable operation (you will have to Google how to do it) but you would still get crashes. You would need at least kernel 4.11 for better Ryzen support but Ubuntu doesn't provide that kernel for 16.04. You could compile latest 4.15 kernel yourself but that requires more than few clicks or simple guidance on this forum thread... that is way out of scope...

Your best bet is to wait for the next nvoc release which will be based on the upcoming Ubuntu 18.04 with kernel 4.15 (ETA May 2018) and use Windows with your Ryzen CPU's in the meantime.

BTW, you stated that you were also trying AMD Gpu's on nvoc. That will absolutely not work with nvoc. There are no AMD drivers in nvoc and all scripts are specifically made for nvidia cards. If you want you can try rxoc that is specifically made for AMD cards but haven't been maintained for a while... I am not sure if fullzero will continue maintaining that OS or not.

Ah, very interesting, that explains a lot. Before i was using a Ryzen cpu i would not get any AMD rig to run with nvOC, thought i was the problem.......didn´t know that it was built specifically for Nvidia cards, now i know. Also i am not knowledgeable enough to compile a linux kernel by myself so i will stick with windows for the moment.
On the other hand, i like nvOC a lot so i hope that in the future i can start using the Ryzen cpu´s to mine with nvOC.

Thank you leenoox, CryptAtomeTrader44 and papampi for clarifying things.
