rvp Hmm. What about the latest Ubuntu?
tried just now. Same thing (Ubuntu now is full Wayland).
rvp I wanted to ask about this before, then plumb forgot: Can you post the xrandr output, and the command you used to set the new mode?

Of course on xrandr output you see 2560x1440 beacause I manually added it to HDMI-0
rvp Did you try the modeline printed/got from EDID? Is it the same as what's generated by cvt?
I remember trying both with modeline from cvt and the one from Xorg.0.log - same issue on HD 7450
Is Intel Arc supported by NetBSD? I haven't seen it in man pages anywhere. It stopped on Iris I think? Since my CPU is AMD Ryzen 9 I can't really use the Intel iGPU. I could only go with discrete Intel Arc GPU.
