I’ve just installed Arch Linux with the Zen kernel, some basic packages, and Blender. However, upon opening Blender, I encountered severe lag when moving objects. Moreover, I faced an issue where I couldn’t select a video card in the preferences. It was Blender from Steam. Later, I decided to install Blender using Pacman, but I encountered the same problem, now with the error message: "Installation validation failed: No module named ‘aiohttp’ [dependencies.py:113]. I’m not sure what steps to take to resolve this issue… Also, everything was okay on the previous rig(GTX 1050Ti and AMD Ryzen 7 1700x) and standard kernel(not zen)
My nvidia packages: lib32-nvidia-utils 535.113.01-1 nvidia 535.113.01-4 nvidia-settings 535.113.01-1 nvidia-utils 535.113.01-2 opencl-nvidia 535.113.01-2 Specs: Nvidia RTX 3080ti Amd Ryzen 7 5800x
The error message is about a missing dependency. Try installing package
python-aiohttp.Not sure why Blender needs an HTTP client or why that would cause lag though.
After installing ‘python-aionhttp,’ I started to see my GPU in the Blender preferences, but Blender still lags heavily.
