Possible upstream bug report: https://gitlab.freedesktop.org/drm/intel/-/issues/4458 (In reply to Patrik Jakobsson from comment #3) One person claims a similar problem disappeared between v5.14.6 and v5.15.7.
As far as I checked, both of the above are about Thinkpad P15 Gen 1, and it's also with Cometlake-H. So this could be a problem with that chip.
Possible fixes are: 9af4bf2171c1 drm/i915/dp: return proper DPRX link training result c8dead5751b8 drm/i915/dp: Use max params for panels < eDP 1.4
Both were backported to the 15.4 kernel in mid/late September.
Right, those should have been already covered. -- You are receiving this mail because: You are on the CC list for the bug.

And the connected monitor itself works no matter whether you get LSPCON errors?
Yes, with Nvidia, but not working with Intel https://bugzilla.opensuse.org/show_bug.cgi?id=1191346 I think, because suse-prime is too old version and errors are not related to this, because on Tumbleweed the monitor works with Intel -- You are receiving this mail because: You are on the CC list for the bug.

Can confirm the bug. I'm using a Lenovo P15 gen 1, can grab more info if necessary
I opened a bug report on freedesktop, but it was closed. Perhaps if you write there, it will be possible to reopen it. https://gitlab.freedesktop.org/drm/intel/-/issues/5048 -- You are receiving this mail because: You are on the CC list for the bug.

So I suspect there's two separate issue exists here:
1. nvidia driver is not handling HDMI hot plug correctly (therefore we need to plug in HDMI cable before boot to get HDMI working with discrete GPU) 2. i915 have some problem with LSPCON (so HDMI output with iGPU is not working at all).
Hope this info helps, and please let me know if there's anything else I can help with (debug log/testing etc).
Thanks for the detailed analysis! Adding Stefan to Cc, as this sounds more like a Intel/Nvidia combo case (being always a headache). -- You are receiving this mail because: You are on the CC list for the bug.
