It does not get get new-monitor events and reconfigure like you wish. If you remove and re-add a monitor, the settings are lost. In desktop environments (DE), *maybe* the display manager does that… but could you describe what is your app setup for the list's benefit? > I have tried adding to the configuration file XRANDR_OPTIONS="-addmode > DSP-0 1680x1050_60.00" without success. Which configuration file? Also: 1. I'm pretty sure DisplayPort outputs have the convention DP-0, DP-1, etc. 2. Did you mean --addmode instead of -admode? 3. Shouldn't you be able to just do --output DP-0 --auto, and maybe --above/--left-of/--right-of, whatever? Could you describe your physical setup please?
