ATI Mobility Readon HD 5650

Recommended Posts

Hey :),

 

I installed successfully Niresh 10.8.2 on my Notebook, but I have a lot of problems to get this card working.

I tried many things from other sites, but nothing works.

 

CPU: AMD Phenom II N930

RAM: 8GB DDR3 1333

Graphic: ATI Mobility Readon HD 5650 1GB

 

It's an Acer Notebook 3 Years & 5 Month old (Acer Aspire 7551G)

 

I hope you can help :)

Hi there and welcome to this forum.

Can you boot the system up (in safe mode)?Is there any option in your bios to use your dedicated graphic card and disable the internal graphics (cpu)?

 

Kind regards

I can boot the system without problems, but my resolution is 1024x768 all all graphics shit is very slow. 

And it's not a built in graphics card. it's on a seperate chip with 1GB own memory

If you are running on 1024x768 and your graphic related activities are going slow, this means your computer uses at that moment the integrated graphics.

What I mean with integrated graphics: A part of your CPU is used to do the graphic rendering. So it act as a internal graphic card.

But in your case you have also a graphic card.

So your computer can use the internal graphics from the CPU or the stronger graphic card.

Most laptops (and I guess yours to) have the feature to switch between the internal graphics (energy saving) for normal use and the stronger graphic card (energy consuming but powerfull) when you are playing games or doing graphic intensive work.

This works good under windows, but this mac distribution has problems because your computer switches between the 2 graphic cards.

Mac os supports a certain amount of hardware which use internal graphics and graphic card switching.

But laptops like yours are not supported to switch between the cards. I know a lot about this because I had the same issue with my previous laptop, and I looked on every forum searching for the answer.

The only solution is to shut off the graphic switching (called Optimus technology with Nvidia cards), or to use a strongly modified kext file.

My laptop didn't had an option to disable the graphic switching. And I looked for ages for a working kext, but I only ended up with hours of wasted time and a computer running mac os in 1024x768.

Maybe someone else has managed to fix this problem, but I haven't fix the problem myself.

I know it's Extremely frustrating... 

Hopefully somebody else on this forum has a fix for this.

Na I still think that's not a problem of the internal graphic thing.

The infos says PCIExpress. In safe mode I have 1024x768 and in normal boot mode I got 1152x864 with a LCD Forced EDID
