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
