Tried the FixVideoResolutionHowto, run the Autodetect script again by below lines
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
sudo sh -c 'md5sum /etc/X11/xorg.conf
sudo dpkg-reconfigure xserver-xorg
didn’t work even made things worse GNOME can’t even show. I have a black screen. Tried also restarting xserver by pressing CTRL-ALT-Backspace, didn’t work either.
Found that my display card is VIA/S3G with 64M and it’s not too old.
At the end I loaded the LiveCD again and found that it could detect the correct display resolution for the LCD HP L1706 I used. May be the SONY Multiscan E200 is really too old.
I have now reinstalled Ubuntu on the same partition, for the 2nd time, and got Apache2, mysql-server and phpmyadmin etc installed using Synaptic Package Manager. The server is running fine. I took awhile to locate the document root as it isn’t under the apache2 folder. It was a bit difficult to locate it under /var/www/
Now I have trouble downloading 184 updates, I see what I can do next.
