Clueless here. I’m running Linux Mint 17.2 on a Asrock ION 330 with a Nvidia ION gpu. The screen is a LG Ultrawide (25UM65) with a native 2560x1080 res. The ION supports up to 2560x1440 but the native res isn’t selectable on nvidia-settings.
On the ‘X Server Display Configuration’ > ‘Advanced’ I can input 2560x1080 manually in the ‘ViewPortIn’ and ‘Panning’ field but it looks very very fuzzy. Non-workable. I’ve tried all possible solutions through Google search but non works.
On other OSes it looks great (on the same hardware) so does anyone have an idea if this is a driver bug or some sort?
