Now (with r339186) it seems that drm-next-kmod is the only usable option.
However, I'm sorry to say:
- it does feel regressive, compared to working without drm-next-kmod with earlier versions of -CURRENT.
I can no longer find a way to reliably suspend (sleep) the notebook.
At the time of writing my part-working configuration is as outlined below.
However – frustratingly – for a while, an hour or so ago, it seemed as if the same configuration was useless; after a point, the screen would go blank (grey) and things would progress no further e.g. no login manager (sddm); no response to Control-Alt-F2; no response to Control-Alt-Delete. The apparent unpredictability leading to a dead-end situation has created a sense of unease; now I'm genuinely afraid to test suspend :-(
For reference
– working at the moment with UEFI, without CSM
