Yes it's normal.   To enable it you must adjust settings in 
your /etc/X11/xorg.conf file.  You must have the proper driver installed and 
referenced in that file under the section "device".  

For nVidia cards it should say:
Driver "nvidia"
For ATI cards it should say:
Driver "fglrx"

If your current driver is nv, ati, or vesa, you are not using a driver with 
direct rendering capability.  (which doesn't necessarily mean that you don't 
have it installed)

Then also in the section "device", you must have the line:
Option "RenderAccel" "True"
