Nuc Pro 14 - Ubuntu 24.04 - Arc Graphics - Missing resolutions

[Wirehead]

Hi,

I'm using an Intel Nuc Pro 14, with Ubuntu 24.04.

In Windows, I can use the full resolutions of my 2 HDMI screens: 2560x1080@60Hz

However, in Ubuntu, it seems the support for this resolution is missing from the driver, and it tops out at 1920x1080@60Hz for both screens, leading to black bars on both sides of the screen.

The listing for this PC  explicitly mentions support for Ubuntu 24.04. So I expect this *should* work, given that in Windows11, the hardware has no issue with it.

Kind regards,

Jeffrey

Hi @JeanetteC_Intel 

It's however not a valid test. The monitor you tested, is 16:9. Not 21:9.

That's exactly the point of this. Monitors fall back to 16:9; and 21:9 is failing on Linux.

Please try with a 21:9 display. You will see the issue is there.

Kind regards,

Jeffrey
