--- Comment #29 from Markus Gaugusch markus@gaugusch.at --- Hi, I've also verified that commit 32167016076f714f0e35e287fbead7de0f1fb179 breaks my system: 01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS880 [Radeon HD 4250] (prog-if 00 [VGA controller])
The attached patch works fine for me. Without the patch, I can no longer use the DVI connector of my (onboard) graphics card, only VGA works.
