Re: [gdm-list] handled=false xservers broken in 2.20.0 vs. 2.18.1

[Brian Cameron <Brian Cameron Sun COM>]

Michael:

This might well be a bug.  I'd recommend turning on debug in the
GDM configuration, restarting GDM and allow it to fail, then
send along the GDM-related debug output that gets sent to your syslog
(/var/log/messages or /var/adm/messages depending on your OS).

This might highlight why GDM thinks it needs to remanage the display
in this case, and assist in debugging your situation.
