I have a custom built gaming computer with 2 monitors, after using Ubuntu on my laptop since 8.04 on up to 12.04 I decided to install the same 12.04 on my desktop which usually runs Windows.
The main problem I'm having now is it only detects 1 monitor and treats it like a laptop monitor. I read in other places this is usually dismissed by the community as a "silly" bug and should be fixed sometime soon as I guess most people have just one monitor anyways.
During installation it detected the 2nd monitor just fine and duplicated my screen onto it but after installation it remained unused. At one point I did use synaptic to export a list of all the installed packages on my laptop to my Desktop for download so I don't know if that fiddled with anything or not.
I use the 2nd monitor pretty often for a lot of different stuff. Is there anyway to fix this, if theres no way to fix it now and I have to wait until some unspecified time in the future for it to be fixed then I need to stop setting up Ubuntu and re-install Windows.
Also, is this Ubuntu specific, I have other Desktops installed so would Kubuntu or some other one be able to detect the 2nd monitor?
