Comment 85 for bug 1968040

I'm reporting this same issue from another distro (Arch in my case). I've added the journal file with the drm.debug parameter. Hope it helps.

A summary of my issues just in case:
- Lenovo T480 Laptop
- Using in combination with Lenovo USB-C thunderbolt 3 dock to drive 2 screens (That are connected through HDMI if that matters)
- When logged into a GNOME Wayland session and waking up from a suspend the screens don't come back on.
- My logitech MX Master mouse doesn't respond anymore
- My Bluetooth keyboard doesn't respond anymore
- Unplugging from Thunderbolt dock makes the system run fine again when it's just the Laptop (bluetooth keyboard and mouse still dont work tho)
- Replugging to dock causes same issues as I had after waking from suspend.
