<2> ubuntu下检查nvidia显卡驱动是否安装ok？———感觉直接从这一步开始就可以了———
使用 sudo lshw -c video 即可，如果在configuration这一行中有driver=nvidia的字符串，那么就说明nvidia的驱动安装ok。但是我的显示为 configuration: driver=nouveau latency=0，证明不ok。这说明安装Nvidia显卡的官⽅驱动和系统⾃带的nouveau驱动冲突，所以这时候要禁用nouveau并重启，输入 lsmod | grep nouveau

按照这篇教程一步步来：Ubuntu20.04 系统禁用自带的Nouveau驱动
