I just bought an Acer K272HUL 27" monitor capable of 1440 resolution to use with a 4k laptop running Ubuntu 18.04 and a Nvidia 960M GPU. I followed the directions here(I needed to use cvt - r since this model blanks)
Everything seems to work great. I get 2650x1440 on the Acer. My problem is how to make this permanent? The instructions say to create an entry in /etc/X11/xorg.conf.d/10-monitor.conf but I don't think I have that file under Ubuntu 18.04. How do I make this resolution option permanent?
These are the files/directories under /etc/X11/ ` app-defaults rgb.txt Xreset.d Xsession.options cursors xinit Xresources xsm default-display-manager xkb Xsession XvMCConfig fonts Xreset Xsession.d Xwrapper.config
