从 ubuntu 16.04 一直升级到 ubuntu 18.04 后，我在 apt-get 升级期间看到很多这样的消息。
/sbin/ldconfig.real: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf.d/nvidia_settings.conf
update-initramfs: Generating /boot/initrd.img-4.15.0-29-generic
/sbin/ldconfig.real: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf.d/nvidia_settings.conf: No such file or directory
有时我的 nvidia 驱动程序可以加载，有时则不能。我目前使用的是 ppa:graphics-drivers/ppa。我尝试过多次清除 nvidia。不想重新安装。问题似乎是 nvidia_settings_conf 的符号链接无处可去，但我不确定它应该在哪里。
输出 nvidia-smi

答案1
我从 16.04 升级到 18.04 后也出现了类似的警告
我已将nvidia-settings.conf其删除/etc/ld.so.conf.d，因为它指向的文件不存在。到目前为止一切顺利...
答案2
server:/etc/ld.so.conf.d$ sudo mv nvidia_settings.conf OLD_nvidia_settings.conf_OLD
此文件与 /etc/alternatives/nvidia_settings.conf 的链接已损坏，请重命名为老的_nvidia_settings.conf_老的在 /etc/ld.so.conf.d 中，因为您不知道是否正在寻找以 nvidia_settings 开头的文件....
答案3
这个问题很明显。错误显示：
/sbin/ldconfig.real: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf.d/nvidia_settings.conf
但实际的链接是/etc/ld.so.conf.d/nvidia_settings_conf
错误：nvidia_settings.conf
正确： nvidia_settings_conf
重命名链接并且它有效。
