I’m using my computer to install Manjaro 23.0.When I using my computer to enter the Manjaro USB-Live to boot the Live but the screen display the conmand line all the time.When the HDMI interface link the I-GPU,the computer working truly.My CPU is R7 5700G,GPU is Nvidia RTX 3060 Laptop and AMD Vega 8.How to resolve the problem
the problem’s content is I use a proprietary driver to boot/start the system
Hello @Source and welcome
That’s because you have a hybrid setup. In short: Nvidia has limited support for KMS, and it is disabled by default, while on AMD it is enabled.
The default setup for this configuration is that nvidia module works on demand and the outputs are not reachable (because of limited KMS support).
You would need to disable the amd gpu in your UEFI Settings, so that only nvidia is recognized. Then nvidia’s output will work on the live session.
You can switch between iGPU and dGPU (in case nvidia module involved) with GitHub - Askannz/optimus-manager: A Linux program to handle GPU switching on Optimus laptops. for example after the installation.
Hope that makes it clearer.
Linux kernel dosen’t support hybird GPU output?
Yes, it supports it: All open source modules.
- intel (i915)
- amd/radeon (radeon/amdgpu)
- nvidia (nouveau) [note: this module has basic support, it probably won’t work on modern GPUs, since it is reverse-engineered]
But not the proprietary module of nvidia. It has limited support for hybrid GPU outputs, only if it works as main gpu.
