Hi,

I'm trying to set up dual Dell Ultrasharp u2311h (23 inch, 1920x1080) monitors with my ubuntu 12.04 partition. I'm running a Radeon 7970HD graphics card with the fglrx drivers (from the ati website), and for some reason my xorg.conf file keeps messing up. Every time I back up xorg.conf, delete it and reboot it seems to works fine. The only problem is that every time I reboot after that, it tends to hang on a black screen with a blinking cursor, forcing me to manually reboot into safemode, delete the file and reboot again.

Does anyone have any idea how to properly set up the xorg.conf file for the system that I have - and more importantly keeping the file from changing every time I reboot?

Thanks for any help!
