I have ubuntu 14.04.1, radeon r7 260x and processor intel i3 4150. ubuntu is installed on partition. its stuck on resolution 1024x768 but my monitor has a resolution of 1920x1080. i have tried installing proprietary drivers for graphics and tried downloading screen apps but i cant change it. On displey setting monitor is unknown. So how to change it?

  • try running this in your terminal : xrandr --output LVDS --mode 1024x768. You can change the resolution to whatever you want – Sachin Kamath Jan 10 '15 at 11:00
