Low screen resolution after clean 18.04 install.

[shomeir]

I installed Ubuntu 18.04 on my wife's Dell Inspirion 620 on a new hard drive and now it only has 1024 x 768 maximum resolution. With 16.04 installed it had 1900 x 1080 resolution. How do I increase the resolution?

Depends on your graphic hardware. Maybe try 'sudo ubuntu-drivers auto install'.

"No drivers found for automatic installation"

But everything worked fine on 16.04 installation.
