[SOLVED] Remote X no longer working on X server after upgrade to current

OldHolborn · 01-23-2016, 03:16 AM

Hi,

Prior to upgrading my desktop machine from 64-14.1 to 64-current last night I was able to open remote windows on the local screen.

This no longer works.

The local machine does still work as an X client, just not as an X server for remote windows.

ssh was not used in any way, it even worked with telnet opening the initial connection so ssh is not the issue.

netstat shows the local, upgraded, machine does not have port 6000 open even though defaultserverargs is empty.

How to re-enable please?

Any chance that you had altered /etc/X11/xdm-config in your previous install to allow XDMCP, but this was overwritten during the upgrade?
This link has information on enabling XDMCP. http://alien.slackbook.org/blog/runn...on-ms-windows/

nope, it's not that.

Looking at my 14.0 boxes which still work fine DisplayManager.requestPort: 0 is active/ uncommented-out

Do you see X command line like this?

Code:

ps a | grep X
28961 tty7     Ssl+  99:11 /usr/bin/X -nolisten tcp

I use ~/.xserverrc to override systemwide setting.

Code:

~ $ cat .xserverrc 
exec /usr/bin/X -listen tcp

That's almost it!

Xorg.man: update to reflect -nolisten tcp becoming default

added "-listen tcp" to defaultserverargs and all is well with the world once more, happiness reigns
