AMD Radeon HD 6470M

[urulókë]

Hey, iam using a AMD Radeon HD 6470M, it's installed in a HP EliteBook 8560p that i have.
I installed the proprietary driver (post-release update) from Ubuntu's driver finder program.
When i start a game with steam it lags as hell, i'am not able to see what's going on and my computer almost freezes because it's running so slow, it almost doesn't react when i press a key, so often i have to force shutdown my computer.

Running a:
HP Elitebook 8560p [www.notebookreview.com]
Ubuntu 12.04 LTS 64bit
Kernel Linux 3.8.0-33-generic
Gnome 3.4.2

For that graphics chip, you'll probably find that you have much better performance with the open source driver. Unfortunately you need a newer Kernel and graphics stack. If you like Ubuntu, your best bet is to upgrade to Ubuntu 13.10 (Saucy Salamander). You can then add a PPA that contains the latest graphics stack, such as this one which worked great for me in the past:

yeah, but my problem is that all never Ubuntu versions aren't compatible with my internet i use.
So i have to use the old version, because the newer ubuntu versions aren't able to connect via PEAP authentication when u don't have a CA certificate.

You will propably still get better performance with open source drivers even in older Ubuntu versions (not that 12.04lts is that old, it has plenty of backports).

Where should i get the Open source drivers for Ubuntu 12.04 lts?

You got those installed, just fglrx replaces it when it's on. Uninstall fglrx and reboot.
Open terminal and follow those commands for clean uninstallation:

sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*
sudo rm /etc/X11/xorg.conf
sudo apt-get install --reinstall xserver-xorg-core xserver-xorg-video-intel libgl1-mesa-glx libgl1-mesa-dri libgl1-mesa-glx:i386 libgl1-mesa-dri:i386
sudo dpkg-reconfigure xserver-xorg
sudo reboot

You most likely have a hybrid laptop, that means by default the system will only use the Intel GPU.

Using the free driver, you can either use PRIME to use the Radeon GPU in a Bumblebee-like way, or you could use the vga_switcheroo to use the Radeon GPU for the whole desktop environment.

yeah i figured out too that it was hybrid and using the Intel GPU, but iam just not sure how i should fix this.

Can I ask, what do you mean when you say that newer Ubuntu isn't compatible with your internet? What issue are you having? It's probably best in the long run to get that resolved.

So the problem with my internet with all newer versions of ubuntu then 12.04 LTS, is that iam not able to connect.
That is because the internet i connect to is using WPA2 --> PEAP --> MSCHAPv2, with login.
But the internet is without an CA certificate, iam able to log into the internet in Ubuntu 12.04 LTS, but in newer versions and other linux distribution, the internet doesn't work.

Ah, sorry that's a little out of my area of expertise.

hehe understandable :)
but iam really a noob at linux, could u help me with how i install the FOSS drivers for my videocard?

[Letalis Sonus]

The free driver is already installed and in use, it's just a little bit old. However, neither the oibaf PPA nor the Xorg-Edgers PPA support your system, you can only install a newer kernel (package 'linux-generic-lts-saucy' contains Kernel 3.11)

Check e.g. the Arch wiki for a short explanation on how to use the Radeon GPU with the free driver via PRIME: https://wiki.archlinux.org/index.php/PRIME
When changing command line arguments for games in Steam, you can use the %command% keyword to mark what should be put in front of the start command - you'll need this for passing environment variables.

one relatively simple way is to check in your system bios for an option to turn off onboard graphics chip and use only the discreet ATI card... once thats done you should see the true performance of your ATI card with the proprietary driver.... and can also try the open source driver to compare the performance...

there are other ways ... vgaswitcheroo as mentioned above by someone else... but unless you really need the onboard chip/switchable function on your laptop then i would just disable it to make life much easier.

[urulókë]

okay, well iam not able to upgrade to a newer system because then i can't use the internet. i have searched a lot for fix and asked a lot of persons about this with the internet, but noone know how.
I will try to disable in my BIOS now :)
