How to change the resolution to 640x480 on reterminal?

I don’t find the other resolution option and I also try xranda command but that command doesn’t work.

Hi, you can change the resolution in the config.

can you show me? how do you change the resolution by config file?

no change by config file
can you send me you config file

To set your resolution to 640x480. Open a terminal and write:

xrandr -s 640x480
