Description Hai 2018-11-15 14:59:03 UTC
When I use AMD GPU pro 18.40 driver with kabylake-g(Vega M GPU), The display can work but I can't enter the GUI. Everytime when I enter the password to log into the GUI desktop, the X-window will crash. When I switch to 18.40 open stack driver, it works OK.

Following is my environment
CPU: Intel(R) Core(TM) i7-8809G CPU
GPU: Vega M(device ID: 694c)
OS: Ubuntu 16.04
Kernel: 4.18.0-rc3
Driver: AMD 18.40 Pro driver

Please use the upstream drivers for VegaM.
Comment 3 Chen Xi 2018-11-19 11:55:17 UTC
Alex, Thanks a lot for your quick response! 

Hai is taking leave. I will follow up the issue when he takes leave.

Could you please be more specific about the "upstream driver" mentioned in your comment? so we could have a try on our side.
Comment 4 Alex Deucher 2018-11-19 13:53:23 UTC
upstream is the open stack.
Comment 5 Cheng 2018-11-21 04:43:03 UTC
Alex,

We've tried the Open Stack, the OpenGL can work. From https://amdgpu-install.readthedocs.io/en/latest/install-overview.html, the Vulkan component is not in the "All-Open Stack" component list, that's reason we try Pro Stack at the beginning.

Following on the "upstream drivers for VegaM", what do you mean specifically? We find that there are two open source drivers:

1) https://github.com/GPUOpen-Drivers/AMDVLK
2) https://www.mesa3d.org/

Is one of them the "upstream driver"?

Either should work.

Vega-M is the integrated AMD GPU in kaby lake-g CPU.
When we use mesa 18.2.2( https://www.mesa3d.org/) the GPU can work with AMD-Open driver. But it can't work with AMD-pro driver, thanks.
