# reschange

Daemon to handle monitor resolution changes

Some wide-screen monitors support picture-by-picture mode where the output of two computers can be shown side-by-side.

When this happens, the monitor EDID is updated to be half the width.  However, currently wayland does not detect the

resolution change, so instead the monitor shows the full wide-screen image shrunk by 50%.

This repo contains a systemd daemon that periodically tells the kernel to re-detect the monitor resolution.

When a resolution change is discovered, it turns the monitor off and on again briefly.  Wayland then reacts as if the

monitor was disconnected and reconnected, discovering the new resolution correctly.

## Build

To create the .deb packagem run `make`

## Install

To install the .deb package, run `make install`

The package installs a systemd service `reschange`, use these commands to control:

```

systemctl status reschange  # current status

systemctl start reschange   # start the service

systemctl enable reschange  # auto start the service on boot

```
