-1. If the `~/.local/bin` directory doesn't exist, create it:
-   ```bash
-   mkdir -p ~/.local/bin/
-   ```
-1. Then create the bash script below and save it into `~/.local/bin/update-virt-display`:
+Below we desribe what to do to solve this issue. The idea is to execute a script that runs indefinitely. The scripts' purpose is to monitor the display output and whenever a change of resolution is detected, it adjusts the display to the newly detected resolution.

-1. Finally, execute the script at the beginning of the session. How to achieve this depends on the window manager being used. For instance, with XFCE go to "Settings Manager" -> "Session and Startup" -> "Application Autostart" and add a new entry with the following details:

+1. As root, make the script executable with:
+   ```
+   chmod +x /usr/local/bin/update-virt-display
+   ```
+1. Then, for each user you want to support, create a `~/.xprofile` with the following content:
+   ```
+   /usr/local/bin/update-virt-display &
