Hi I have a computer with switchable graphics.

Both are AMD, Mobility Radeon HD 5470 and Mobility Radeon HD 4000 series.

If I install the linux legacy drivers, the computer doesn't boot at all, not detecting the Radeon HD 5470 and if I install the normal drivers, it crashes, not detecting the Radeon HD 4000 series.

I read the post about checking with the PC manufacturer, but I already checked with my Acer and they don't offer me any solution as both cards are AMD.

What can I do to be able to run my PC and switch between cards?

Thanks in advance.

The AMD Mobility Radeon™ graphics driver supplied by the notebook manufacturer is customized for the built-in display and the features and functions specific to the notebook. It is recommended to use the drivers provided by the notebook manufacturer.

If installing an operating system other than the one currently supported by the notebook, the notebook may not meet all requirements. As such supported graphics drivers may not be available.

The AMD Mobility Radeon Driver Verification Tool will display the following error if it fails to validate the graphics hardware. This is due to incompatible hardware/configuration in your notebook. Please contact the notebook manufacturer for assistance.


The AMD Mobility Radeon Driver Verification tool helps you determine your notebook’s compatibility with generic AMD Catalyst Mobility drivers. It helps to prevent incorrect installation on incompatible notebooks which may lead to disabled features or functionality.

 

If you experience difficulty while using the generic AMD Catalyst Mobility drivers, we recommend reverting to the driver provided by your notebook vendor. Please contact your notebook vendor for their most recent graphics drivers.

Yes I read that already.

The thing is that it was working perfectly with the normal drivers until AMD decided to create the "legacy" branch of drivers for Radeon HD 4000.

Now, as one of the cards is legacy and the other uses normal drivers, it doesn't work anymore.

My laptop brand is not offering me support as it is a problem only about AMD Drivers with AMD graphic cards.
