"Unknown Monitor" and cant increase resolution beyoud 800x600

[mpatrick]

First of all thanks to Sharaq for your excellent post and help.

I followed his instructions and the resolution changed and worked fine

However as with many other posts I could not keep this permanent by editing the /etc/gdm/Init/Default file as he suggested

As wizel post in thread http://ubuntuforums.org/showthread.php?t=1370258&page=2 I confirmed that the gdm file was not being used at startup hence reason why pasting xrandr commands into this file did not change resolution upon restarting!!

So I then created script file /usr/local/bin/increase_resolution.sh as detailed in wizels other post in thread above

However when I created this file you can see resolution changing once starts up. More annoyingly using this I had to remove my clock and CPU monitor applets on the desktop as showing in middle of screen.
Even more annoyingly I noticed that when starting up from cold cairo dock was in middle of screen and changed colour on lots of menu's looks to grey.
