[Bug 659544] [NEW] ATI driver detects both VGA and DVI port on ATI Radeon X300 for Acer Monitor

 

Public bug reported:

Binary package hint: xserver-xorg-video-ati

ATI driver detects both VGA and DVI port on ATI Radeon X300 (which has only a VGA port) for Acer Monitor.
Screen mirroring works (with some artifacts) and at a low resolution (monitor supports 1920x1080).  However, non-mirroring configurations generally don't work.  I've occasionally gotten the DVI to work at 1360x768 with the VGA off even though there is no DVI port and the VGA is 1920x1080 (the VGA is correctly detected at 1920x1080, but just comes up blank until I use my thinkpad fn+F7 key to turn mirroring back on)
