This page is intended to include 'How-to' style debugging/troubleshooting information for GNOME.
Enable gnome-session debugging
The recommended first step for trying to debug issues in GNOME related to various GNOME components is to enable the debug flag in /usr/bin/gnome-session. To do this, edit /usr/bin/gnome-session as root and add the the following option to the end of the last line: --debug:
/usr/bin/gnome-session exec /usr/libexec/gnome-session-binary "$@" --debug
Then, logging into GNOME will result to debug log messages sent to /var/log.
Enable Debugging in GDM
Edit /etc/gdm/custom.conf and add:
/etc/gdm/custom.conf [debug]
Enable=True
Then restart gdm via /etc/init.d/gdm restart, which will result in additional log messages being added to /var/log as well as being added to /var/log/gdm logs.
