Created attachment 375853 [details] xorg.0.log Description of problem: I have a laptop (HP Compaq 8510p) and a 24" monitor (HP LP2465). When I connect the monitor to the DVI port on my laptop the monitor does not light up. Version-Release number of selected component (if applicable): $ rpm -q xorg-x11-drv-ati xorg-x11-drv-ati-6.13.0-0.11.20091119git437113124.fc12.x86_64 How reproducible: Everytime. Steps to Reproduce: 1. Install F12 2. Connect DVI monitor to laptop 3. Boot Actual results: Laptop monitor lights up. DVI monitor *doesn't* light up. (GDM puts login prompt on DVI monitor regardless. Makes hard to log in!) Expected results: Laptop and DVI monitor to light up. Additional info: Connecting secondary monitor to VGA output on laptop works. $ lspci | grep Radeon 01:00.0 VGA compatible controller: ATI Technologies Inc M76 [Radeon Mobility HD 2600 Series] 01:00.1 Audio device: ATI Technologies Inc RV630/M76 audio device [Radeon HD 2600 Series]
Could we get output of the command dmesg after you try to do the connecting please? Thank you in advance
