Hi all, I am running a Lenovo T520 with two graphic cards on board: Intel an Nvidia.
As you see here it is an GF119M [Quadro NVS 4200M] (rev a1) --- snip --- lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Gra phics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [Quadro NVS 4200M] (rev a1) --- snap --- The documentation requires the nvidia-legacy-*390xx* driver to use, but as hard as I try, this will not work. However, what is working is the driver nvidia-legacy-*340xx.* (I am using bumblebee) This one is working like a charm, but can not be build with kernels newer than 5.10-18.*. So I have to stay with this kernel. What I believe is, that the documentation from NVidia might be wrong and Nvidia told wrong, to say 390xx is for NVS4200. On the other hand, it might be a bug, that the 340xx can not be build with newer kernels (I discovered the compilation is crashing due to some missing files. I filed a bugreport of this almost a year ago), which inhibits users, to use newer kernel-versions. This is a pity especially for notebooks, where you can not exchange the GPU. I just wanted to inform you, if someone got into the same trouble as me, wondering, why it does not run. Thanks for reading this. Oh, before someone tells: I do NOT want to use nouveau! Best regards Hans
