cirrus_dri.so 是干什么的，网上只看到有 ciccus_drv.so

[Nangle]

cat /var/log/Xorg.1.log 看看有没有什么发现。

开 ssh ，让我上去看看

@awen233333 这是驱动吧。可能驱动有问题。看能不能重装下驱动。

显卡驱动

[jim9606]

这个是 cirrus 的用户层驱动，虚拟机常用。
通常由 mesa3d 提供驱动，ubuntu 通常是 libgl1-mesa-dri 提供。

[huangzxx]

试试
apt-file find cirrus_dri.so

[awen233333]

@jim9606 装了，没找到这个动态库

[awen233333]

@Nangle 没有发现，找不到相关的东西

原则上你应该是需要根据官方文档重新安装 xorg

其实吧，你可以再装一台虚拟机，从这台新装的虚拟机上拷个动态库过去。一般 iso 镜像里面有初始的动态库，加载镜像选修复模式重新链接动态库就行了。当然，之后整的动态库就没法这么搞了。
