Hello sir,
I’m using a Lenovo Legion Pro 5（with a cpu: AMD Ryzen 9 7945HX and gpu: RTX4060 laptop）.
While when I boot my ubuntu 20.04, the system information seems that I am using llvmpipe (LLVM 12.0.0, 256 bits). More over I can not control brightness and I can not connect a second monitor.
I’ve already installed nvidia driver and I can get the correct information with command “nvidia-smi’’. And I also use “prime-select nvidia“ to change the origin ‘‘on-demand” to “nvidi’’, these all seem not effective.
here’s my nvidia-bug-report.log
