 |
|
I installed Gentoo with the Calculate Xfce v. 15 overlay on 3 separate partitions (/, /home and /swap). After rebooting the grub appears but the screen stays black after that.
Any suggestion to correct this will be appreciated.
TIA |

I have the same laptop and use Gentoo on it. I had big problems to configure Xorg, because the nvidia card writes into the memory of the intel card. A very exotic solution to save power. Follow this guide:
https://wiki.gentoo.org/wiki/NVIDIA_Driver_with_Optimus_Laptops
Try at first to switch in bios to "discrete graphics"
I had also big problems with 2 eselect opengl switches. Now I have "eselect opengl nvidia" and "eselect qtgraphicssystem native", but I use KDE Plasma. XFCE runs fine before
I'm at work now. I will post my running xorg configuation when I'm at home. |

dhinds,
Make the intel graphics system work first. Thats quite conventional.
Add the nVidia graphics using the Optimus guide later.
By building on something that works, you can back out changes if you don't get it right first time.

Here is my w520 configuration. The configuration is not perfect, but works. I searched two weeks to find this settings. I hope it will help you.
| Code: |
eselect opengl list
Available OpenGL implementations:
[1] nvidia *
[2] xorg-x11
|
The next switch caused big problems with KDE when is switched to opengl. Perhaps not important to you, because you use xfce.
| Code: |
eselect qtgraphicssystem list
Available Qt Graphics Systems:
[1] native *
[2] opengl (experimental)
[3] raster (default)
