Geforce GTX 960M missing resolutions with nvidia drivers installed on Ubuntu.


I have installed nvidia-driver-435(proprietary, tested) drivers on my Ubuntu OS.
I have Geforce GTX 960M graphic card.
Previously, on Windows I could choose 3440x1440 (21:9) resolution for my ultrawide display but I can’t do it right now.
Please help me to use my beautiful display, any help appreciated!
