This is an update to share the experience.
I installed LM 13 Cinnamon x64.
then upgrade it to 14 by APT commands. (http://www.howtoforge.com/how-to-upgrad ... a-with-apt
It took ages to download and upgrade but the result is perfect.
All the hardware components recognized by lm14 without single problem including graphic card and resolution. Cinnamon works perfect.
there is a bug or some misarrangement in the installation process. Specifically on mdm initialization and/or parameter problem at xorg. Unfotunately I am not knowlegable enough to trace the root of the problem.
I believe that this parameter or mdm settings could be fixed very easily by experienced developers which will make it possible for all of us to use instsllstion dvd's directly.
I am very glad to have lm final release on my computer.
Thank you for all the support and suggestions from you.
