Radeon HD 6450 hardware acceleration

Hi there

I'm running mint 17.2 on an AMD64 platform, with cinnamon.

I gather that I won't get hardware acceleration with my Radeon unless I install the Radeon drivers from the ATI web site. I did download and auto install the most current drivers from there, but x11 crashes when I reboot my computer.

Is there some special recipe to install the drivers? Should I use drivers from canonical? Did I do the wrong thing auto-installing rather than saving them first and using terminal window?

For the time being I have reinstalled mint 17.2 and am using the default software acceleration. Seems a waste to leave out my GPU's capabilities.

Please advise how to get hardware acceleration working. I did search this forum but couldn't find my specific issue addressed.

Thanks from the newbie.... Chris.

Launch Driver Manager utility, does it offer a list of available drivers for your graphics card ?

Menu -> Administration -> Driver Manager

That should install the driver for you. No need to go to the ATI website and download it yourself.

Thanks, guys and/or gals!

I've installed the recommended driver from driver manager, and all seems to be ok.

So simple, I'm glad I posted in the newbie forum!

I've certainly seen a big improvement in the video quality.

Is there a way to formally test and confirm the hardware acceleration? glxgears is giving me 1150 fps, but this isn't any more than it was doing before I installed the drivers! Flash video on youtube is still showing software rendering and software decoding.

Thanks for helping me out guys!

Newbie chris.

Did you reboot after you enabled the new drivers?

Yes, I did. Is there a specific test I can run to determine the status of hardware acceleration and rendering?

Thanks
