"-listen tcp" is needed for Xorg 1.17
Last modified: 2015-11-10 14:33:12 UTC
Starting with Xorg 1.17, TCP is off by default and a new "-listen" option has been added to explicitly re-enable it. (http://cgit.freedesktop.org/xorg/xserver/commit/?id=cc59be38b7eff52a1d003b390f2994c73ee0b3e9) So gdm now has to pass "-listen tcp" if DisallowTCP=false is set in gdm/custom.conf. However, doing that would cause a fatal error with Xorg 1.16 or older, which did not have that option yet. Fun.
Created attachment 315189 [details] [review] Check xorg version and use -listen if new enough
Thanks, pushed with minor tweaks as commit 3f59fa0da5168451898db63e51e312ce894af0c1 .
