Radeon and Nvidia GPUs working together at the same time
Radeon and Nvidia GPUs working together at the same time
I've chosen to move from Windows to Linux (PopOS). I'm attempting to mirror my prior configuration: using a Radeon GPU for two side monitors and an Nvidia GPU for the main display. My setup is budget-friendly, relying on refurbished or replaced hardware. Currently, my main monitor and GPU are functional (Nvidia). However, when I power off and connect the Radeon GPU, the system crashes with black screens. Using "nomodeset" once worked but no longer does after reinstalling PopOS repeatedly without success. I've looked into configuring xorg, but the documentation is unclear. I've shared some details in attached files, though they don't reflect the Radeon setup because booting fails. I'm a semi-pro system admin, not comfortable with GUI tools or display managers like xorg, but I'm okay working around it via command line. lshw xrandr.txt
Hello and thanks for reaching out. I’m unsure how to address your query, but I believe there are individuals here who could help. There are many young players and casual gamers, including myself, as well as some very experienced users. I’m not among them. It might take some time. This seems like a sophisticated question that only certain people can fully grasp, and visitors come and go. I urge you not to give up—I’d be willing to assist if I could, though I’m still struggling with older Windows versions and my Linux experience is limited at best. GL
The scan didn't show any indication of running both cards simultaneously for different displays.
I've set up Arandr before, but it only works when everything is detected. I attempted to install the amdgpu-pro driver, though it says it's only for Ubuntu. I used PopOS with the NVIDIA image, and I'm planning to try nomodeset again today. EDIT: Would using nvidia-xconfig and adding the Radeon GPU make a difference?
They often suggest pop_os for newcomers, but it's meant for specialized setups. Installing drivers usually requires a custom tool with limited guidance. Honestly, I’d choose Ubuntu instead. Share the precise error message you encounter during AMD driver setup, and consider using amdgpu without the extra flags.
You're just starting with Linux GUI versions and ran into similar problems. The drivers you installed via the PPA repo worked initially but didn't fully resolve the issue. Swapping the HD5450 for HD7770 helped, but it only has one DVI-D output, which isn't ideal. It seems the newer card you're using might not be compatible with your current driver setup. Double-check if the driver you installed supports your specific hardware model.
