I have a Dell Laptop at work (i don't really know which model it is and it don't say it anywhere).. fedora 20 work perfectly fine until I connect an extra monitor... when I do that, sometimes it freezes, sometimes don't... it's really annoying.

I checked lspci, and found that I got 2 video cards:

lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus PRO [Radeon HD 8850M]

So, probably, it is some issue with the Radeon card, since intel usually just works.

What can I do to fix that?
