I have a Thinkpad T495 with an AMD Ryzen Pro 3700U and Vega 10 graphics. Everything seems to be working besides suspend/resume which is crucial for me since I'm on the go a lot. I had to build my own Qubes R4.0 ISO to get the installer to work due to it needing a 5.0+ kernel for the graphics driver. I installed `kernel-latest` from qubes-dom0-current testing but still didn't work. After trying every kernel option on the face of this Earth I decided to use an experimental Qubes R4.1 build as some things were pointing to dom0 Fedora 25 being the issue. On dom0 Fedora 31 it's still an issue with a 5.4 kernel. Has been driving me nuts as I've spent almost the whole day trying to figure the issue out.
When I suspend, it clearly suspends but when I open it back up the screen is off but the power LED is on. I can hear the fan spin up for a bit but nothing happens. CTRL + ALT + Backspace does nothing. I also tried switching to text mode before suspending with CTRL + ALT + F2. Nothing... I also disabled the compositor in XFCE to give it a try in both R4.0 and R4.1, no difference. It totally seems like an X server or amdgpu issue but I really don't know what to do. I don't have any VMs running when I test the suspend and I don't have a sys-usb VM to take that out of the equation. Any ideas? I'm scratching my head over here and I'm at a loss on what to try next.
