答复: VegaM DP dpms issue

[Qu, Jim]

Hi,

Please give more details about the issue, such as OS, kernel version, amdgpu driver version, dmesg log, Xorg log.


Some suggestions:

1. Make sure that hybrid GFX has enabled on your system.
2. The important issue, make sure Which GPU is mDP phy connected. If it is from iGPU, that mean the dGPU is for offloading, it maybe some issue about Intel driver.
2. If the display is from dGPU, By default, all the rendering job is done by Intel. make sure you used the last modesetting DDX, I just fixed a modesetting PRIME sync issue for Intel + AMD/NV hybrid GFX issue.

Thanks
JimQu

Hi

I'm pretty sure unless you're offloading using DRI_PRIME=1 then it'll be your Intel graphics that'll be driving the displays

I'd recommend you raise a bug on https://bugs.freedesktop.org/ under DRI then DRM/Intel

Make sure you attach your dmesg and Xorg.0.log and hopefully they'll be able to help

Cheers

Mike

I am having an issue with intel NUC8i7HNK with AMD Vega M. I have three Dell U2415 monitors connected to one mDP daisychained. When the monitors go to sleep (dpms) trying to wake up the monitors after half hour or more fails, touching the keyboard and mouse. Only way is a hard reboot. Same monitors connected to other systems wake up fine. I seen old bug reports on this issue but seems I'm hitting this bug again.

If this is not the proper list please let me kno. --Thanks
