From 57fb5bb5733fb69c98a9c2fecb06ed4cd7b922f3 Mon Sep 17 00:00:00 2001 From: Mike Gabriel Date: Wed, 11 Jun 2014 10:42:04 +0200 Subject: Add 027_nxcomp_abstract-X11-socket.patch. In proxy mode server let NX proxy attempt connecting to the abstract X11 socket first, and only fallback to the file system socket, if the abstract socket is not available.
