I'm trying to get a second monitor working on a Acer laptop running 10.04. It seems to work; the monitor is recognized and automatically configured (which is very nice, by the way!).

However, the monitor's refresh rates seem to be configured incorrectly. I thought "no problem, I'll just tweak the xorg.conf"... only to find that there is no such file. - I've used this monitor (A 19'' Acer LCD) before on this laptop, using an older version of Ubuntu (8.10 and 9.04), so it should be compatible.

Reading other threads here, I tried using a few versions of:
sudo dpkg-reconfigure xserver-xorg
But none of them really did anything, and no xorg.conf has shown up yet.

Any help would be appreciated.

A few spec highlights:
  • Acer Aspire 5670
  • ATI Radeon Mobility X1600
    "Mesa"/"radeon" driver. Auto intalled by Ubuntu.
  • Acer AL1916 (The extra LCD)
    Ubuntu identifies it as "Acer technologies 19''"
