AMD Radeon Pro SSG Boot Issue with Linux

Question asked by mazinga2305 on May 27, 2018

I have issue with AMD radeon PRO SSG with Linux

I have two Radeon Pro SSG on Dell Precision T7600, and they work correctly with Windows 10.

But for linux, I can only boot with recovery mode.

And when I try to install the driver, it says that "WARNING: nomodeset detected in kernel parameters, amdgpu requires KMS, WARNING: amdgpu dkms failed for running kernel".

When I try normal boot, the screen shows the black screen, and nothing proceeds.

I followed the instructions of following web pages, and nothing worked.

I tried Ubuntu 16.04.2 Ubuntu 18.04, and also tried different kernel version (4.4.0, 4.15, 4.16, 4.17).

 

Is there anyone who knows how to resolve the issue?
