I've got an Ubuntu 20.04 workstation, featuring an NVidia RTX2080 gpu, and connected to a widescreen with a native resolution of 3440x1440.
For basic needs, the display works fine : by default, it's running at native 3440x1440.
But if I go into Settings->Display and try to select an alternate resolution, the choice is scarce, limited to 3440x1440, 1024x768 and 800x600. That's it. No other intermediate resolution is proposed.
It happens that I need to test such intermediate resolutions, like 1920x1080, but can't do it on this station.
However, when running a full-screen game which offers a choice of resolution on the same computer, a ton of choices are offered, and they all work great, indicating that there is no issue with neither the display, nor the gpu, nor the driver. Hence, it seems a limitation of Settings->Display.
I've tested multiple driver versions, they all feature the same (currently running 460.32.03).
Has anyone met the same kind of issue ? Is there a solution for it ?
