显卡出错
显卡驱动突然崩了
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
重新安装驱动
sudo apt-get remove nvidia-* sudo apt-get autoremove
sudo apt-get autoremove
sudo nvidia-uninstall
sudo ./NVIDIA-Linux-x86_64-381.22.run -no-x-check -no-nouveau-check -no-opengl-files
切换nvidia显卡/inter
sudo apt install nvidia-prime
sudo prime-select nvidia
其他错误

最近在ununtu18上又遇到了这个错误,使用sudo ubuntu-drivers autoinstall重新安装也不行,仔细看发现编译时报了这个错误
Error! Bad return status for module build on kernel: 5.4.0-58-generic (x86_64)
应该是自动升级内核导致的错误,先去软件和更新里设置从不自动更新。有人用降低内核的办法解决了,但我试了下没效果,最终查看Log通过升级gcc-8解决问题\
sudo apt-get install gcc-8 g++-8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 10
sudo update-alternatives --install /usr/bin/cc cc /usr/bin/gcc-8 10
然后重新sudo ubuntu-drivers autoinstall ,确认编译时没问题,reboot解决问题

在新机上装ubuntu时,出现花屏现象,查了下是显卡原因,用如下方法解决:

在安装时,分辨率不正常,使得界面显示不全,可通过alt+f7强行拖动
