Using MacOSX to attach to RHEL7 via GDM
I'm upgrading some servers from RHEL 4 and 5 to RHEL 7, and am having problems connecting to GDM from my Mac.
On the Mac, I used to do
Xnest :screen-num -query hostname
and I'd get an X11 session to log in to.
MoboXterm on the PC works fine with RHEL7 - once I drilled the right holes in the firewall.
Anyone know what secret sauce is needed to get past the
Oh no! Something has gone wrong.
A problem has occurred and the system can't recover.
Please log out and try again.

Dear Verne,
Such an upgrade path is unfortunately generally unsupported because the system is apt to end up in a state where your old configuration files are not digestible by the newer versions of the software. It's recommended that you perform a clean installation of RHEL 7. If you have RHEL 6, though, you can try the Preupgrade Assistant, which is designed exactly for these migration attempts. More info at https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Migration_Planning_Guide/chap-Red_Hat_Enterprise_Linux-Migration_Planning_Guide-Upgrade_Tools.html.
Anyway, is there anything interesting in /var/log/gdm/* or /var/log/Xorg.0.log? An error message indicating a compatibility issue, that is.
