Portable mode - split display

[petter5]

I 'm experementing with running two instances of O , one standard and one portable version under Linux ( Xinutop) I'm trying to set a fixed display resolution for each instance so that I can run each instance in " fullschreen" mode with a fixed/ limited display width. Testing is done on a Thinkpad T42 with a 1400x1050 display. Would it be possible to configure in the ini file max resolution for each instance of O , for example one 800 widh x 1050 height and one 600 width x 1050 height. What I'm trying to archive with this is to get each instance to run fullscreen mode while still limiting the width so that the whole screen can be used effectively. also,to be able to have this setting in the ini file would make it easy to arrange the windows separately side by side
