Just wanted to compare notes - I'm trying Fedora on my 2026 XPS 16 with the OLED display and everything seems to work except that the display seems to be stuck at ~30Hz (hard to tell but it's definitely less than 60) no matter what I set the refresh rate to and dynamic brightness control seems to do random things. Pretty sure it's a display problem and not an iGPU problem because an external display is totally fine.

ETA: Oh, and I guess more generally on the refresh rate, Linux doesn't seem to recognize that the panel is VRR at all. I can set it to 60Hz or 120Hz, but the setting doesn't seem to have any effect.
