Hello everyone,
I just installed the CentOS 6.8 updates from the CR repository,
and then I rebooted the server. I run some software to make weather
images on a website, and I have run into a problem. When I do it, the
software, as it tries to plot the image, says:
Xwindow: unable to connect to display
It just stopped working when I did the updates. Has anyone else seen this,
or have an idea on what to look for to get this fixed? To plot it, I
use syntax's of
machine: 0
machine: 1
machine: 2
Which lets me plot it using virtual frame buffers (Xvfb). When I do xhost
+ servername , it says it has been added to the control list...but it
still doesn't fix the issue. Does anyone know what I may be doing wrong?
Also, doing an "xhost +" does not help, either, and in /etc/gdm/custom.conf,
I have:
DisallowTCP=false
Any ideas would be greatly appreciated. Thank you!
I tried reverting to the previous version of x11-Xvfb-server in CentOS
6.7, and that did not help at all. I am wondering if something is up with
GDM or the X11 server, but port 6000 isn't even showing up now as active.
Anyone?
Gilbert
