Display resolution not shown in Ubuntu

Problem

I uninstalled my NVIDIA drivers using this command:

$ sudo apt-get purge "nvidia*"

I rebooted my computer and logged into Ubuntu. I was greeted by a desktop of resolution 1280x768. This was far lesser than the native resolution of this display, which is 1920x1080!

When I opened System Settings -> Display, only the above low resolution was available in the dropdown!

Solution

Online solutions point to using xrandr to pick the display resolution and make it permanent. Since my system was due for a new LTS Enablement Stack, I went ahead and updated the Linux kernel and X server as described here.

After rebooting from this update, my desktop was back to its full native resolution! 😄

Tried with: Ubuntu 14.04
