This is becouse the graphical card has too litle memory. At least it
thinks so.

Try 'dpkg-reconfigure -plow xserver-xorg'

You shouldn't set values for modern monitors. They tell the graphical
card
all it needs. Only for buggy monitors it's needed.
Try only ' option "DPMS"' as is the default anyway.

No, Xorg can't detect sufficient memory, as you can see in your log.
You should prob. tell Xorg the size.
We really need to also see /etc/X11/xorg.conf

It is needed, as your posted Xorg.0.log (good!)

You should prob clean your paths. They have changed

As seen, lots of different resolutions are detected for the monitor,
but not sufficent ram in graphical card to run them.

Xorg panics and exits when it cant find a suitable resolution for the
card.
