My laptop is a Dell XPS-13 running CentOS 7. It has a 13″ 1920×1080
screen and it’s a bit difficult for my mid-40s eyesight. Fedora and Debian, on this laptop, give me the option of choosing 1600×900 which is much easier for me to read but CentOS doesn’t show this resolution as available.
I followed the steps I found in a post on stackexchange using xrandr, substituting 1600×900 where applicable and it worked but, once I
rebooted, it went back to 1920×1080 with no 1600×900 option in settings-display.
Is there a way I can add 1600×900 resolution the list of available resolutions in settings-display?
