Uncommon GNOME issues with FastX
Problem:
Cannot interact with menus and/or windows may be transparent in GNOME. Applications within GNOME are unresponsive.
Solution:
Use the following command to launch GNOME
/etc/X11/xinit/Xsession gnome-session
Problem:
Failed to connect to session bus: Error spawning command line dbus-launch
Solution:
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.
Problem:
GNOME will not render correctly or won’t start.
Solution:
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.
