Description Michał Górny archtester

As of the last xdm users in Gentoo, I think it may actually be a good idea to disable the xdm auth support. It's not supported by other DMs, and causes issues with libreoffice and some SDL games.

Shortly saying, the issue happens when an app using X11 uses exec() to spawn another app using X11.

$ lowriter 
XDM authorization key matches an existing client!/usr/lib64/libreoffice/program/soffice.bin X11 error: Can't open display: 
   Set DISPLAY environment variable, use -display option
   or check permissions of your X-Server
   (See "man X" resp. "man xhost" for details)

I'd say the simplest solution would be to disable xdm-auth and let xdm use the same ol' auth as other DMs do.

I've checked it and it's enough to add to xdm-config:

  DisplayManager*authName:    MIT-MAGIC-COOKIE-1

(therefore disabling XDM-AUTHORIZATION-1)

If noone objects, I'll commit it in a few days.

@Michał, please wait a bit before acting on this.

@x11, I must say I have very little knowledge about this and have no objections either way. What say you?

Thanks

xdm-1.11.1-r3 is now unmasked in tree and makes xdm-auth optional.
