Uncommon GNOME issues with FastX


Cannot interact with menus and/or windows may be transparent in GNOME.  Applications within GNOME are unresponsive.


Use the following command to launch GNOME

/etc/X11/xinit/Xsession gnome-session


Failed to connect to session bus: Error spawning command line dbus-launch


Use command:
echo $(dbus-launch)

Output should look something like:
echo $(dbus-launch)
DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-YZZ6DUobaE,guid=0f311a3fc11fbaad26eeef195ef3cc28 DBUS_SESSION_BUS_PID=328

If an error message is returned, there is likely a problem with a library.
echo $(dbus-launch)
/usr/bin/dbus-daemon: symbol lookup error: /usr/bin/dbus-daemon: undefined symbol: XML_SetHashSalt
EOF in dbus-launch reading address from bus daemon

If you receive an error, run the following command to see if a library is the issue.

ldd /usr/bin/dbus-daemon

Any output not pointing to the system libraries is an issue.


GNOME will not render correctly or won’t start.


Check to see if you have a video card on the host server.  Usually NVIDIA.

VirtualGL is required in order to utilize the video card.  The following are instructions on setting up and using VirtualGL with FastX.
