I can't activate my gpu when running Ubuntu 14.04.

I've tried to follow the steps here but without any luck. http://xpressrazor.wordpress.com/2013/10/08/enable-and-use-open-source-radeon-drivers-in-a-muxless-hybrid-graphics-intelamd-setup/

The output of cat /sys/kernel/debug/vgaswitcheroo/switch always return that my discrete card is in the DynOff state and I can't switch between them.

$ cat /sys/kernel/debug/vgaswitcheroo/switch
1:DIS: :DynOff:0000:01:00.0

Also, as my card is not supported by ATI so the installation of the proprietary drivers is not an option, at least as far as I'm aware.

$ lspci -nn | grep VGA      
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09)
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6730M/6770M/7690M XT] [1002:6740] (rev ff)

$ xrandr --listprovidersProviders: number : 1
Provider 0: id: 0x47 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 5 associated providers: 0 name:Intel

Is there any way to enable my discrete card?


Don't know how and why, but after some tries I was able to install the proprietary AMD drivers and the AMD Catalyst Control Center successfully. However, only the drivers from fglrx-updates worked. After several attempts (and reboots) I was able to configure the amd graphics (using the command amdconfig --adapter=all --initial) and now I can switch between the integrated and discrete video cards, which is quite awesome! Finally I am able to use my AMD graphics on Ubuntu.
