ubuntu重启后显卡驱动掉了
|
ubuntu20.04重启后，显卡驱动掉了。 nvidia-smi检测不到显卡，双屏幕，只点亮了一个屏幕。 到系统about中检查，看到显卡驱动是llvm。 说明显卡驱动真的掉了。 参考 ubuntu重启后丢失驱动 查看已安装显卡驱动 ls /usr/src | grep nvidia显示 nvidia-525.89.02 如果没有dkms的话，安装一下 sudo apt install dkms因为我的系统是再生龙安装的，里面已经有dkms了，就跳过安装dkms的过程了。 dmks安装nvidia sudo dkms install -m nvidia -v 525.89.02用dkms status查看 nvidia, 525.89.02, 5.15.0-69-generic, x86_64: installed virtualbox, 6.1.38, 5.15.0-56-generic, x86_64: installed virtualbox, 6.1.38, 5.15.0-69-generic, x86_64: installed没有执行dkms install前，dkms status只有virtualbox这两行。 查看下显卡 nvidia-smi
如果还不行 如果还不行 查看显示如下 sudo dkms status [sudo] password for udeer: nvidia, 525.125.06, 5.15.0-75-generic, x86_64: installed (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) nvidia, 525.125.06, 5.15.0-78-generic, x86_64: installed版本不对，估计是昨天安装virtualbox时，重装了virtualbox-dkms把环境搞乱了。 解决办法：卸载重装 sudo dkms remove -m nvidia -v 525.125.06 --all sudo dkms install -m nvidia -v 525.125.06 sudo dkms status nvidia-smi 正常了 |
