Instructions for Setting Screen Resolutions in Ubuntu with GNOME using Xrandr #Linux
Although I’m personally totally fine with Unity, GNOME continues to be a hugely popular desktop environment for very obvious reasons: namely, use what works for you. As such you might find useful these instructions for using Xrandr to configure screen resolutions, provided by Kenyan embedded developer Karibe.
I have a HP W2072a LED screen for my work machine on which I ran Ubuntu with Gnome desktop environment. After installation or upgrade, I only have limited screen resolution modes. I got the supported resolutions from the datasheet. The best resolution for my screen from earlier experimenting was 1440 x 900 @ 60Hz. The following steps will help configure the VGA adapter for this resolution
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
