7900XTX: No display output (Lg C2) after latest build

[daschlurp]

Everything was working great when I built linux-mkopec-git using the AUR PKGBUILD 2 days ago. My screen worked with 4k 120hz rgb 4:4:4 either with or without HDR and vrr enabled (Im on Sway WM arch linux). Only bug I found was that dpms was flaky and display showed "No-signal" when dpms turned off. I rebuilt the kernel today to check for new patches and now the display wont initialize = "No-signal". What change could have made this happen?

Did you try to turn of/on the display multiple times? Some TV's have this bug, and need to cycle few times

Same on LG C5, found a person on reddit and on another forum that report the same, both LG users as well.

Checked out an older commit - 435360c on the hdmi_frl_stable branch - and it works again.
So some of the following commits must have changed something that the LG TVs don't like.

I'll try to grab some logs later.

Same issue here with same GPU + LG C3, I confirm if rebuild with 435360c it works.

Can also confirm that a rebuild with older commit - 435360c works for me.

I wanted to participate in testing as well and got no output with RX 7900 XTX and hisense 65eq7pro TV.
Seems related to this issue.

Just to be sure: I tried to reboot multiple times, tried to turn TV ON and OFF multiple times and I do get output with CachyOS kernel 4k120hz

Hey,

Still on commit - 435360c and its been working almost flawlessly. Still no fix for the latest commit breaking FRL on my system. Possible to fix this to build the latest kernel?
