Trying to get fglrx to work on a hybrid GPU solution

[Guest]

Hello everyone!

I'm new to the Linux community, therefore, I'm having some issues to get my laptop running perfectly. I'm on a Dell Inspiron 7520 with a dual GPU solution: Intel IvyBridge Mobile graphics & AMD Radeon 7730M. The thing is i can't get my 7730 to work. Any application i run always use the Intel and the ones that allow you to choose which adapter to use don't even show the 7730 as an option. Currently it's running X. Org X server drivers ( Kubuntu driver manager shows it ) and it works perfectly, no crashes or bugs regarding Kwin effects for an example. However i'd like to run games on the dedicated GPU . I did a lot of reading online and tried various tutorials on how to install AMD proprietary drivers since they reportedly can manage hybrid GPU systems. But every time I go over the tutorials and install fglrx, my desktop stops working and end up with only the Linux terminal, and to get it back on i need to remove all the propietary drivers using apt-get and erase the xorg. conf file.
A discription on what I tried and the outcomes:

I already tried installing fglrx and its other packages through:

• Driver Manager
• Muon Package Manager
• Direct Download from the AMD site and run the installer
• Apt-get

Apart from, the Instalation from the AMD website that didn't even finish saying i had no compatible adapters, all of the above installed the drivers. But when i tried to run the Catalyst Center they all gave an error saying i had no compatible adapters and i should run amdconfig. I went online and saw i had to run to configure the drivers to a hybrid system:

sudo amdconfig –initial –adapter=all

Still no use, i got every time “no supported adapters detected”. And everytime i had the fglrx installed and rebooted the system i ended in the Linux terminal with no desktop and had to fix the way i described above. Finally, I tried this tutorial(couldn't post link since this is my first post, will post link for reference as soon as i can):

Hello guys …. and gals,
Well as described in the title in this post I will tell you exactly how to install the drivers for AMD hybrid graphics with no problems in Ubuntu. First of all you need to execute the following command:

sudo apt-get install fglrx fglrx-core fglrx-amdcccle fglrx-dev fglrx-pxpress

now you should run the following command:

sudo amdconfig –initial –adapter=all

But this will give you an error “no supported adapters detected”
Don’t worry and reboot the system and you will be introduced with ……. A black screen but no need to panic.
now press CTRL+ALT+F1
Login using your user name and password and then retype the command.

sudo amdconfig –initial –adapter=all

If you’re lucky enough the command will get executed successfully. reboot and you will be able to use your machine.
To make sure that the amd card is the one in use run:

sudo apt-get install mesa-utils
glxheads

It should print “GL_VENDOR: ATI Technologies Inc.”

And when i ran amdconfig after rebooting it actually executed and configured the xorg. conf file (checked using vim). When using the command:

sudo amdconfig --list-adapter

It showed the 7730M correctly. However after rebooting for the second time i still had no desktop. Now, i ran out of ideas as all the tutorials only tell me to do the same steps i'd already tried. Is there any other way other than the fglrx drivers to manage the two gpus and force executions on the dedicated card?

Thanks in advance to anyone who can help!
