at last

For days I was unable to properly set the native resolution of my LG Flatron wide L194WT monitor, within my intel graphics media accelerator 950. I turned upside down my xorg.conf, quick-fire reconfiguring the X server

sudo dpkg-reconfigure xserver-xorg

and restarting it, and rebooting... Finally, the workaround was to simply replace the i810 default ubuntu drivers with the intel ones:

sudo apt-get install xserver-xorg-video-intel

following this ubuntu forum thread.

Now I can fully enjoy all the 1440x900 pixels of my home screen (needless to say, with the full beryl cube fancy!)
