Bug ID: 107493 Summary: Screen goes blank while loading drm driver Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: esebaro@gmail.com
I have a PC with: MB: Asrock AM1B-ITX CPU: AMD Kabini Athlon 5350 APU iGPU: Radeon HD 8400 / R3 Series Displays: DVI Asus, HDMI Samsung
Kernels: 4.12/4.14/4.15/4.16/4.17 Drivers: radeon, amdgpu, amdgpu-dc
Booting in UEFI mode, EFIFB/SimpleFB
When the drm driver is loaded on system boot or when is loaded manually the screen goes blank. The screen content reappears after the driver has been loaded. I assume switching from efifb/simblefb to radeon/amdgpudrmfb causes this.

--- Comment #1 from Alex Deucher alexdeucher@gmail.com --- Please attach your xorg log and dmesg output. What display connectors are on your system and which are you using? Are you using DVI and HDMI at the same time?

The mainboard has two video ports, DVI and HDMI. I use the DVI port. I can test the HDMI port too if that helps.

So this report is about the screen temporarily blanking while the driver initializes? If so, that's not really a bug, getting rid of that would be an enhancement.

Yes. I didn't know that's how AMD drivers load. Starting with 4.14 there's also a screen wide artifact when loading the driver so I thought the screen blanking is a bug.

Those artifacts should be fixed as of 4.18.
