    AMD switchable graphics support


    I recently switched my PC for a gaming laptop. However it runs 7970m and Intel HD 4000 in switchable configuration. I'm not exactly sure how this works but it seems to run the Intel HD 4000 as a default and switch up to the AMD card when configured.

    Does Linux, any distro/driver, support this? It's a bit wonky even in Windows 7 but does work after some config. So far I've only tested ut with Ubuntu since this was most likely to work easily. It detected I needed the AMD drivers and installed them but after reboot it couldn't actually see my card, only the Intel.

    I can't force enable anything in the bios either, I have the XMG bios which looks like it has been some what locked down to basic settings only.

    You may want to have a look at the bumblebee project. Afaik automatic detection/switching of the GPU's is not yet supported.
