** Description changed: Upon upgrading to the latest HWE edge kernel (from 5.11 to 5.13) on 20.04, I found that my screen won't work if my laptop goes idle (screen off) or wakes up from suspend. Reverting to 5.11 resolves this for me. This seems to be a common issue across many distributions and appears to have been fixed in 5.14. I'm using a ThinkPad P14s AMD Gen 1 with Ryzen 7 4750u (integrated graphics).
