Bug ID: 101988 Summary: blackscreen after modprobe amdgpu on R9M370X mac edition Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: blocker Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: newincpp@gmail.com
Created attachment 133154 --> https://bugs.freedesktop.org/attachment.cgi?id=133154&action=edit dmesg after `modprobe amdgpu` and getting blackscreen
I don't know if this is specific to R9M370X - mac edition but I couldn't reproduce it on other AMD PC I have.
This is fairly simple to reproduce, I just have to mount the amdgpu and I get a black screen on my main screen and my main screen only (my second screen is fine)
I don't have this problem using radeon with the exact same kernel config. dmesg is saying everything is fine and X11 log is irrelevant because it happen _before_ startx. I am using Linux 4.12.4-gentoo.
