You may need to quit X Quartz and restart it, e.g., by running “xterm” or “xterm -fullscreen” and then maybe select the xterm from X Quartz’s Window menu.<br><br>Make a careful note of the key sequence you need to get out (it’s Command-Option-A).<br><br>You may be able to achieve the same effect with other window managers by tweaking configuration files. I haven’t looked into that.<br><br>Regards,<br><br>Rob.<br><br><blockquote type="cite" style="color: rgb(0, 0, 0);">On 13 May 2025, at 17:23, Nick via X11-users <<a href="mailto:x11-users@lists.apple.com">x11-users@lists.apple.com</a>> wrote:<br><br>Is there a way to launch X and use the entire display including background, not to be shared with Quartz WM and other UI windows?<br>_______________________________________________<br>Do not post admin requests to the list.
