This tutorial shows how to set custom screen resolution in current Ubuntu releases, including Ubuntu 20.04, Ubuntu 22.04, and Ubuntu 24.04, on either Wayland or Xorg session.<\/p>\n
So this tutorial is going to show you another way to add your favorite screen resolution if it’s not available in Display settings.<\/p>\n
In the case, I’ve the default 1920X1080 (16:9) resolution. However, I prefer 1600X900 (16:9) a little more which is not available in settings.<\/p>\n
In this tutorial I’m going to add video mode option as Kernel parameter. The good<\/b> side is that it works on both Wayland and Xorg.<\/p>\n Downsides<\/b> includes:<\/p>\n And after adding the parameter, the custom resolution should appear in Display settings, 1600×900 for instance:<\/p>\n Firstly, you have to find out the current Display name. To do so, open terminal from the system application launcher:<\/p>\n When terminal opens, run command:<\/p>\n This is a single command separated into 2 lines.<\/b> It checks all the sub-folders under ‘\/sys\/class\/drm<\/i>‘ directory. For the sub-folder includes ‘status<\/b>‘ file with ‘connected<\/b>‘ as content, the folder name exclude ‘card?-<\/i>‘ part is the device name we need.<\/p>\n As the picture shows, it’s eDP-1<\/b> in my case.<\/p>\n DON”T edit the files<\/p><\/div>\n Option 1.) edit Grub configuration file.<\/b><\/p>\n a.)<\/b> Open terminal from system app launcher. When it opens, run command to edit the config file:<\/p>\n Replace When it opens, add video=eDP-1:1600×900@60<\/b>, in my case, as value for “GRUB_CMDLINE_LINUX_DEFAULT”.<\/p>\n IMPORTANT:<\/b> you have replace video=eDP-1:1600×900@60<\/b>:<\/p>\n There are more flags for the video mode kernel parameter. See the documentation<\/a> for detail.<\/p>\n b.)<\/b> After saving the changes (for nano, press Ctrl+S, then Ctrl+X.) Finally apply changes by running command:<\/p>\n And reboot.<\/p>\n Option 2.) use Grub Customizer:<\/b><\/p>\n Grub-Customizer, the popular graphical tool offers an option to add the Kernel parameter.<\/p>\n Install it from Ubuntu Software if you don’t have it. Then launch it and navigate to General Settings<\/b> tab. Finally add the value and click on Save<\/b> button.<\/p>\n![\"\"](\"https:\/\/ubuntuhandbook.org\/wp-content\/uploads\/2021\/05\/resolu-before.png\")
