So Colin's suggestion worked! Once i logged in with Ubuntu classic desktop (no effects) i could set the resolution i wanted (via monitor preferences) and everything works. I am somewhat embarrassed that i didn't see that option when i first tried this.
The only issue i am left with now is that screen size appears to be taken from the larger 19" monitor. This means that the mouse can fall off the top or bottom (or both) of the smaller monitor, depending on where i position the smaller monitor in relation to the larger one (again, in 'monitor preferences'). This isn't much of an issue however as the GNOME menus bound the size to which applications maximise in the smaller monitor. So i am happy to live with this. One last thing then, since i had enough memory to run the resolutions but the advanced effects were messing up the presentation, is it worth filling a bug on this? Thanks again, for all the help. j On 11 August 2011 11:52, Jim Price <d1vers...@hotmail.com> wrote: > Hi James, > > On 11/08/11 10:14, James Morrissey wrote: >> >> - Asus A6Rp; Asus A6 series entertainment notebook > > Rats - the ASUS page with the spec on it isn't working in Firefox or > Chromium... > > It should be here: > > <http://support.asus.com/knowledge.aspx?SLanguage=en&p=3&s=41&m=A6Rp&os=&hashedid=aHR4WKHzgC0UPCGP> > > but the link doesn't work. > >> - I had a look in Bios but couldn't work out how to set any of this. >> In the Bios the only seemingly relevant header was under 'Display' --> >> Dsiplaye Settings ---> Video Devices.
