Metro-X supports a hot-key exit. This is useful for terminating the X server if the last client in your .xinitrc or .xsession does not provide a way to exit the session. The exit key combination is [Ctrl]-[Alt]-[Backspace].
When configuring Metro-X you can select several screen resolutions. You can then change resolutions on the fly while running your X server by pressing the appropriate key combination. To switch to the next resolution, press [Ctrl]-[Alt]-[+]. To switch to the previous resolution, press [Ctrl]-[Alt]-[-].
Metro-X supports hardware panning. This lets you set the virtual resolution higher than the monitor's physical resolution. Windows can then extend beyond the screen's physical boundaries and can be viewed by scrolling into the extended area.
Metro-X supports up to four screens which can all be controlled simultaneously with a single keyboard and mouse. This allows you to run many applications without overlapping windows, and is particularly useful for image-processing work.
In a multiple screen configuration there is one X process, one mouse, and one keyboard - but several screens. The mouse/cursor can be moved between the different screens. Clients connect to the different screens with the syntax -display :0.X where X is the screen number.
Use up to four of any one card from the following list:
Metro-X provides many predefined configurations, sorted by language and country. These configurations are selected through configX (section 6.3.3).
