We have a workstation in our group that has a KNPA-U16 motherboard, and an AMD RX560 GPU which works most of the times. The Operating System is Kubuntu 20.04 and the kernel version 5.8.0-59.
Now the problem appears when we do not use the workstation for some time and than try to access it in front of it. Behaviour is as following:
The screen appears for a short period of time (varies between ~0-10s) and than goes black. As said the time varies, I once was even able to login before the screen went dark. There is no possibility anymore to wake it up after that event. Its is reachable via ssh though.

We had the problem for a long time now (~ 1 year, visible in SMBIOS event log) and tried some things:
- Taking the Graphics card out of the PCIe-Slot and plugging it in again
- Installing a new kernel
- Installing the amdgpu proprietary drivers
- Turning off all sleep settings in Kubuntu we could find
- Using pcie_aspm=off
- Using a different screen (DVI / Display port)
- Changing some BIOS Settings related to PCIe
However nothing we do seems to change anything. What makes this problem so hard to tinker with is that it only appears if the PC is not used for some time. So it is really a pain to test anything.
Does anybody have an idea what the error could be or where we could start looking based on the log?
Update we tested the graphics card in a different PC with Windows and it worked fine. Afterwards we installed Win 10 on the same PC and it is also working without problems. So it seems to be the combination GPU + motherboard + KDE neon. Linux seems to allow some kind energy saving state that doesn't go well with the mainboard. However we have searched a lot and did not find any hibernating option we did not turn off.
