Comment 44 for bug 1724583

Adrian, thank you very much. Your advice saved me a lot of money.

I unfortunately own an MSI GX70 notebook with two GPUS: Radeon HD 8650 G Richland and Radeon HA 8970 G Neptune.

It wouldn't load without nomodest option in grub configuration. While fglrx lasted, it was bearable. After 16.04, however, nomodeset started to block installing amdgpu driver.

With MUTTER_ALLOW_HYBRID_GPUS=1, however, the notebook booted without nomodeset, also it switched to integrated Radeon HD 8650 G Richland automatically.

I will still have to figure out how to switch to the discrete GPU when it is required but the notebook is already getting to be usable again after one and a half years.
