If you have ATI graphic card 2xxx-4xxx like me. You will found problem such as kubuntu can not find you graphic card adapter. It's pain. I spend my time google then I have got keyword "fglrx-legacy-driver". Googling it then something like this come up!!  http://www.ubuntuvibes.com/2012/10/how-to-install-amd-catalyst-legacy.html  . I tried it and it's works. Currently I use external monitor , that doesn't not work now. I just something I found during googling are make your kubuntu know you have attached external monitor run kdesudo amdcccle goto display manager then check if you see 2 screens active (that's a good luck) goto terminal, run command sudo aticonfig --initial ( hope you will get xorg.conf which contain detail of current state ) reboot then wish you luck

I alway deal with external monitor issue. Last time on Kubuntu 11.10 , it's gone by a lot of hack xorg.conf, system settings/display and monitors. Now, it's back. I tried to use old way but I just think if I tried $ kdesudo (or sudo ) amdcccle then I enabled multi-monitor with little setup then restart. And Again it seem like I get in cloning mode. But I just get it amdcccle ( ati control settings ) then enable multi monitor mode again. After that everything is seem to look good now.

Open your terminal, then $ sudo amdcccle then change your monitor's layout and restart your box !!! everything should be what you want :)
