Title: 120 Hz on Lemur Pro?

So it was about time to get a new Laptop for work to replace my 2013 Air, and I decided to get a Lemur Pro to try something different.

In the Gnome display settings it lists 120 Hz options:

External Media: You need to be logged in to view this.

This was a bit of an unexpected bonus... but it doesn't actually work. GL/Vulkan programs still just run at 60 Hz. xrandr also just lists 60 Hz. Is this a bug that Gnome lists 120 hz, or a bug that it doesn't work? Not quite sure what else to look or search for.

Closest I get is this: https://www.reddit.com/r/pop_os/comments/gzp50k/120hz_setting_in_60hz_screen/

The Lemur possibly has a 60Hz screen, which would make this a bug.

I'd write to them and ask.

I'd start with looking if the hardware actually supports 120 Hz
My impression it does not.

Yeah. I mean I assumed it was just a vanilla 60hz display when I bought it since it didn't say otherwise. Gotta be a bug in Gnome though, I can't any X tools that produces any of the 120-ish hz modes. (Admittedly I have no idea what I'm doing. \o/)

I sent them a bug report for it. Will see where that goes. Ta!
