+Subject: [PATCH] Xephyr: fix setting physical output size
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Providing physical size via RRRegisterSize() is not enough - physical
+size is a property of the output, not resolution and needs to be set
+separately. Furhermore, get the physical output size using RandR if
+-output is used, to match specific output, not the whole screen.
+
+With this, `Xephyr -output OUTPUT_NAME` properly copies not only
+resolution but also physical size of the named output.
