** Description changed: The point is, the radeon venus pro hd 8850m cannot be turned on on linux, you can try official or open source drivers. I think the problem is by the dynamic switchable mode thats make a vga switch on windows without get a black screen, the discrete gpu are connected by hardware to the internal intel graphics card that cannot be turned off or you will have no image xD. Also on windows the intel drivers+amd must be instaled to turn amd graphics on, but on linux thats impossible. Already tryed all drivers from amd, on ubuntu 14.04 and 14.10, it will install ok and when ubuntu restart it will be on low graphics mode and only back to work if i purge then. "You are sure the both vgas are working on linux? If you can i will give my Latitude 3540 to you! hahaha By the f***** Dynamic Mode switchable graphics and the impossibility to turn the intel adapter off by bios settings, Its impossible to turn on the Venus Pro Radeon - HD 8850m on ubuntu! Already tried with versions 14.04 amd 14.10 too." + + + --- + ApportVersion: 2.14.7-0ubuntu8.2 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: pp 2497 F.... pulseaudio + CurrentDesktop: Unity + DistroRelease: Ubuntu 14.10 + HibernationDevice: RESUME=UUID=ed697923-f15a-491d-893c-5aad47c2a4ba + InstallationDate: Installed on 2014-10-24 (169 days ago) + InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.2) + MachineType: Dell Inc.
