How do I make 1920x1080 screen resolution permanent? Lubuntu 20.04 Virtualbox Windows host

I found this:

xrandr --newmode "1920x1080" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr --addmode Virtual1 1920x1080
xrandr --output Virtual1 --mode 1920x1080

Gets me the resolution I want until I start Linux back up and it returns to 600x800.

How do I make Lubuntu keep these settings after restarting?

Refer to the manual

You'll note resolution settings can be changed at Preferences -> LXQt.settings -> Monitor.Settings

Clicking APPLY will cause the settings to be saved only for the current session, but they won't be saved for subsequent sessions (logins).

If you click SAVE as well; the changes will take place on subsequent sessions as well.

Note: This is a LXQt setting; so it does not impact your machine until after you've started and logged into a LXQt session; ie. Lubuntu uses sddm as the greeter, which is not part of LXQt thus has it's own settings.
