I'm running a Debian Sib installation on a Dell Latitude E6540 laptop.
It has a 8790M card :
# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars XTX [Radeon HD 8790M]
I have read (http://support.amd.com/us/kbarticles/Pages/AMDCatalyst13-8LINBetaDriver.aspx) that HD 8700 Series were supported but when I run the installer I get a popup error window that says it is not.
Opensource drivers do not work at all either for my hardware.
I cannot get dual screen work correctly.
Could someone help me ?
