question # 10782 solved the problem with running the following in the terminal:
$ sudo gedit /usr/local/bin/startxgl.sh

 #!/bin/sh
 Xgl -fullscreen :1 -ac -accel glx:pbuffer -accel xv:pbuffer & sleep 2 && DISPLAY=:1
 cookie="$(xauth -i nextract - :0 | cut -d ' ' -f 9)"
 xauth -i add :1 . "$cookie"
 # Start Gnome
 exec gnome-session
it may ask you to install glx, if so then do it. it will give you a info balloon saying what command to issue if you want to disable the new changes. i just saved the command in the text editor and labeled it "disable glx disable command" .

if you don't have glx installed then run this in your terminal:

sudo apt-get install xserver-glx

then you can run the following in a terminal:

$ sudo gedit /usr/local/bin/startxgl.sh

 #!/bin/sh
 Xgl -fullscreen :1 -ac -accel glx:pbuffer -accel xv:pbuffer & sleep 2 && DISPLAY=:1
 cookie="$(xauth -i nextract - :0 | cut -d ' ' -f 9)"
 xauth -i add :1 . "$cookie"
 # Start Gnome
 exec gnome-session

that should get it.
