Mirror mode when connecting 2 monitors

[Maksim-Garikov]

In ThinStation, there is xrandr, which allows you to edit the monitors' setup and specify the monitor layout using parameters. Additionally, there are parameters that can perform automatic configuration of the resolution for a monitor set to "mirror" mode. To change the settings in thinstation.conf.buildtime so that when connecting two monitors, it works as separate screens, you can try modifying it to use dualscreen. However, if that didn't work, you might want to ensure that the following parameters are set accordingly:
SET_RESOLUTION_MULTIMONITOR_EXPAND='expand'
SET_RESOLUTION_MULTIMONITOR_AUTOSCALE='off'
These settings should configure the system to use the monitors as separate screens rather than mirroring them.
