While the computer’s on, hit ctrl+alt+F1 to go into a terminal and run: If you get a black screen on restarting, don’t panic, it probably means a typo or other syntax error of some description. Once you’ve saved nf in /usr/share/X11//, restart your computer and you should have your brand new resolution available and set as default. So for reference, mine looks like this: Section 'Monitor' You can add additional resolutions that already exist in the list xandr shows just by putting them in quotes and adding them to the end of the modes line. The modename is the bit in quotes (so 1920x1080_60.00 in our earlier example).

This will open a blank text file, into which you want to paste the following: Section 'Monitor' In order to create our spangly new resolution we need to create /usr/share/X11//nf The display interface name is the bit before ‘connected’ so in this case ‘HDMI-1’. This will give you something along the lines of: 2) We need to find the display interface name We’re only interested in the second half, so make a note of everything from modeline onwards. Once you’ve executed the command you’ll be presented with something like this You’re probably safe to keep the refresh rate at 60 unless you have a good reason to do otherwise. We do so by going into terminal and typing “gtf x y r” where x is the horizontal resolution, y is the vertical resolution and r is the refresh rate (which is largely irrelevant since LCDs are the norm). So, what do we do with that information? Well first we need two bits of machine-specific information. It turned out after some Googling that xorg config files had been moved to /usr/share/X11// /etc/X11// nf (the proper replacement for nf) path (as specified by the Archlinux Wiki) was nowhere to be found, and creating it did nothing.nf is A) deprecated B) couldn’t be generated by Xorg :1 -configure.xandr based commands reset whenever you restart, and while you can (apparently) set the commands to run on startup, my attempts to do so proved fruitless.Well, I never found out what gave, but here’s how to fix it: When I went to set it up on its destination display it refused to display anything above 1280×720. When I set it up with my TV it recognised 1920×1080 as a viable resolution no problem at all. Earlier I was setting up a new Lubuntu powered computer which was to be connected to a TV via HDMI as its primary display.
