Public bug reported: Binary package hint: xserver-xorg-video-ati
I am unable to enable multiple monitor support using a Dell Optiplex 780 desktop system with a Mobility Radeon HD 3470 with two monitors connected by displayport using displayport -> DVI adapters under Ubuntu 10.04 64bit. Once Ubuntu starts, the secondary monitor goes to sleep while the primary monitor functions as expected. I have not installed the fglrx driver and I have not tweaked any xorg settings. With the monitors set to clone in Gnome's monitor configuration, the primary monitor is on and the secondary is in standby. If I enable multi-monitor support, then the secondary monitor will turn on and the primary will turn off. I expected/hoped that both monitors would work. For verification, both monitors do function properly under a dual-boot of Windows XP on the same hardware.
