I installed the AMD GPU driver (amdgpu-pro-18.50-725072-rhel-7.6) in Centos 7.6
(kernel: 3.10.0-957.el7.x86_64) for this GPU model (AMD Vega Series X 64).
The installation was based on the guidelines in the documentation and everything went smoothly.
The problem is that when I boot the machine I cannot enter the graphical interface where the usernames appear to login.
It looks like it stuck somewhere. However, ssh connection works and OpenCL also works. Then I logged in a terminal and
checked that the display manager is active. When I restart the service it blinks to a black screen and returns to the same window.
However in the dmesg report, the following message appears:
“gnome-session-c: segfault at 10 ip 00007f89a31e84e2 sp 00007ffe2b26de80 error 4 in libdrm_amdgpu.so.1.0.0[7f89a31e1000+b000]"
For the record, this message and the same behaviour remains even when the GPU is not plugged in the machine.
I also tried startx command and reports:
"xinit: connection to X server lost".
Can someone give a hint for this problem?
