hobbestec, The monitor is specified as "Screen 0" and I have used the syntax as follows:
user@Mojo:~$ xrandr --output screen 0 --mode 1440x900_60.00
to no avail... ill try it again to make sure.
sukujgrg, I think that Ubuntu10.04 has no xorg.conf file, as it was done away with in a previous version but that its possible to create one to use, however, as far as I understand, I would only bother doing that if I was able to get the resolution to change at the command line, and I wanted to make it a permanent fix. Am I wrong?
I will post a couple more of my attempts, but im at work in another town this week, wont be back till Thursday.
