I finally got round to a remedy (I hope)  of  the above problem.  I  installed 
xorg7.5  with the nouveau (http://nouveau.freedesktop.org/wiki/) driver.  
However I have some problems:-

-----------------
PROBLEM A:
 I followed the instructions  for installing ADDITIONAL fonts given here ( 
http://www.linuxfromscratch.org/blfs/view/cvs/x/x-setup.html ) My xorg.conf 
fils has lines such as 

The files section of xorg.conf has lines such as 
      FONT PATH "/usr/X11R7.5/share/fonts/X11/abcdefg"  (abcdefg =font 
directory)

however  on starting the X , the logs show  the following:-
##########
WW) `fonts.dir' not found (or not valid) 
in "/usr/X11R7.5/share/fonts/X11/dejavu".
	Entry deleted from font path.
	(Run 'mkfontdir' on "/usr/X11R7.5/share/fonts/X11/dejavu").

(WW) The directory "/usr/X11R7.5/share/fonts/X11/OOtruetype" does not exist.
	Entry deleted from font path.
(**) FontPath set to:
	/usr/X11R7.5/share/fonts/X11,
	/usr/X11R7.5/share/fonts/X11/misc/,
	/usr/X11R7.5/share/fonts/X11/TTF/,

-----------------------
PROBLEM B:

On starting X  with   the instruction   
X -retro -config ~/xorg.confXXX  ( 
http://www.linuxfromscratch.org/blfs/view/cvs/x/x-setup.html)
the  Control+Alt+Backspace does not work.  I could not find a way to   stop X 
save crashing the setup.

-----------------------------
PROBLEM C  ( realy some clarity)

Is it advisable to have 
 Load  "glx"
in the modules section  of Xorg.conf for this   driver?


advice welcomed

ps     sorry about the long post but I  hope it helps the context.
