i have two ATI video cards. Onboard RS690 (x1200) and PCIe R9-290
RS690 only works with radeon open source since Amd doesnt support it anymore
R9 only works with new ati drivers (i try with catalyst 13.12)
lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS690 [Radeon X1200] 02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii PRO [Radeon R9 290]
each card works well individually in a fresh installation
all attempts for work together were disastrous, so the question is:
how to install RADEON Open Source and Ati Catalyst (fglrx) together ??
