** Description changed:

+ * GNOME's monitors.xml is starting with <monitors version="2">, and that 
MATE's monitors.xml is starting with <monitors version="1">
+ * The monitors.xml file name is defined here for MATE: 
https://github.com/mate-desktop/mate-desktop/blob/master/libmate-desktop/mate-rr-config.c#L44,
 and here for GNOME:

  #### Expected behaviour
  cinnamon is using a dedicated name, cinnamon-monitors.xml. This doesn't cause 
the file to be overwritten by the display preferences if other desktop 
environment are used on the same distro. If MATE and GNOME followed the same 
approach, the file name would be mate-monitors.xml, and gnome-monitors.xml, 
respectively.
  
  #### Actual behaviour
- Disclaimer: GNOME's monitors.xml is starting with <monitors version="2">, and 
that MATE's monitors.xml is starting with <monitors version="1">
- 
  GNOME's monitors.xml:
  
  ```

  #### Steps to reproduce the behaviour
  Both GNOME and MATE can be installed on the same distro. Both DEs are 
installing "$HOME/.config/monitors.xml" via manually configured display GUI 
preferences:
  * GNOME via `$ gnome-control-center display`
  * MATE via `$ mate-display-properties`
  
  Steps I used to reproduce the issue in Ubuntu 22.04 (as a virtual machine):
  * Log into GNOME
  * Ubuntu comes with GNOME, so install MATE in addition: `sudo apt-get install 
mate-desktop-environment-extras mate-desktop-environment`
  * Run `$ gnome-control-center display`, change the "Resolution" to 1600x900, 
click on the "Apply": This will 1) generate "$HOME/.config/monitors.xml", 2) 
[Screenshot_ubuntu-22.04-desktop-amd64.iso-clone_2023-07-24_23_43_56](/uploads/dc4ba73ddfae955fcafa948e3a164581/Screenshot_ubuntu-22.04-desktop-amd64.iso-clone_2023-07-24_23_43_56.png).
 Close the window.
  * Log out from GNOME. From the display manager, log into MATE.
  * As you can see, the [screen resolution (1600x900 configured in GNOME) not 
used by 
MATE](https://github.com/mate-desktop/mate-control-center/assets/6416073/adffa08e-cf08-499d-8dc3-9e7800e4d7e9),
 instead a fallback resolution is used.
  * Run `$ mate-display-properties`, just click on the "Apply" button (you 
don't have to click on the "Keep this configuration" button that pop-ups in the 
dialoge-box), it will overwrite "$HOME/.config/monitors.xml"
  * Log out from MATE. From the display manager, log into GNOME.
  * As you can see,
