I tried different versions of Ubuntu from 11.04 to 11.10 beta, but got same problem.

My desktop pc configuration is, - intel core i5 2400 - DH67BL Motherboard - Inbuilt motherboard graphics - No extra graphics card attached - Acer-H193HQV 18.5" Monitor - 2GB RAM - 250GB Harddisk

Problem : Ubuntu can't detect my monitor and saying it Unknown. Moreover, monitor's original resolution is 1366x768 but in the list of resolution there is only 1024x768 and 800x600 are there.

Try to install a new graphics driver for your system, a ppa with the newest drivers can be found here.

Add it with

sudo apt-add-repository ppa:glasen/intel-driver

and after that do

sudo apt-get update` and a `sudo apt-get upgrade

Install the xserver-xorg-video-intel using the command sudo apt-get install xserver-xorg-video-intel.
