Well met everyone,
I got Gentoo running on my ThinkPad E460 a while ago, my third succesfull install, the other two being on my MacBook Pro 2012 (first one) and Acer Nitro 5.
The MacBook used Intel graphics, so just installing Mesa took care of everything. For my Acer, I went the other way and forced it to use NVIDIA only, which also worked just fine.
Now, the E460.
I have dual-graphics, Intel iGPU, and a Radeon dGPU.
BIOS doesn't let me deactivate the iGPU, and I understand that's because the dGPU is wired behind the iGPU.
I have installed Mesa drivers, as well as Radeon drivers. I installed Skyrim to test out, and I used launch options DRI_PRIME=1 as instructed to enable Prime offloading.
However, offloading doesn't work right, and only iGPU is used.
Here is part of my make.conf

Am I missing something here? Have to admit, Optimus isn't my strong suit, and it's actually the first time I use a Radeon card under Linux. |
