Screen resolution problem

I'm using Zorin 9 Lite on an old Dell 4550 that previously ran Win XP Pro. The default resolution of 1920x1080 ran fine in XP but keeps poping in and out to 1024x768 and back in Zorin. I've been able to fix it using the commands below, but need a permanent solution.

jacatone@Dell4550:~$ xrandr

Hi, sorry friend but Zorin 9 Lite support ended in April this year. Lubuntu forks only run 3 years tops.

I thought this was an LTS distro? I'm still able to get updates.

Oops, my bad - it should run out in April 2019 according to Lubuntu website - think it was the first Lubuntu to go beyond 3 years. Will do some searching.

Hi, Please see if the solution given here helps you:
