最近我不得不修复因图形错误而冻结的笔记本电脑。您能找到错误的原因和解决方案吗?

答案1

从专有 GPU 驱动程序 PPA 安装最新的稳定 NVIDIA 驱动程序和 Optimus 支持:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-355 nvidia-prime
sudo reboot

答案2

您可以通过在终端中运行来安装驱动程序

sudo apt-get update
sudo apt-get install nvidia-346 nvidia-prime

答案3

您是否尝试过这个:

sudo apt-get install xorg-xserver-video-all

这样也许能很好地发挥作用。
