There are many viruses under Windows, and there are many advertisements, so you are not bothered, so you want to install a Linux system. I have tried Ubuntu and You Qilin before. I have been working hard to toss centos 7, and I have seen it hard to see Deepin. I installed Deepin 15.9 in the integrated graphics card. It feels very good. I have a feeling of seeing each other and I am planning to use it. Heart into Deepin. However, I was stuck when I installed the discrete graphics card. My graphics card is Nvidia GeForce GTX 750 Ti, the driver I downloaded is NVIDIA-Linux-x86_64-418.43.run, the installation error log: "The Nouveau kernel driver is currently in use by your system. This driver is incompatible with the NVIDIA driver" (see attached). This is the same computer, this graphics card and driver, I installed successfully under centos 7, I do not know why it can not be installed under Deepin (15.9)? "This is the same root (both Linux). Why is it too urgent?" I wonder if everyone has such an experience? How is it solved? I don't know which driver should I use for the Nvidia GeForce GTX 750 Ti? Where can I download?
