我已经在 Ubuntu 18.04 上使用了一年，突然在成功启动后几秒钟开始冻结。我可以看到桌面几秒钟。它要求输入 gnome-keyring 密码，3-5 秒后出现一个破碎的屏幕。
我尝试从 ppa:oibaf/graphics-drivers 安装新的 ATI 驱动程序。它似乎可以启动五次，但现在又坏了。
我尝试使用 Ctrl+Alt+Fx 切换到控制台，但它完全冻结了。但 SysRq + REISUB 可以工作。
我尝试在日志中搜索某些内容，但找不到线索。
恢复模式处于低图形模式，但运行正常。以下是日志中的一些屏幕截图（更利于识别错误消息）。日志 1 日志 2
我不知道粘贴部分系统日志是否有用，但是有用。

Apr 12 05:06:59 iki-pc gnome-shell[1360]: Some code accessed the property 'getUniqueBusNameSync' on the module 'util'. That property was defined with 'let' or 'const' inside the module. This was previously supported, but is not correct according to the ES6 standard. Any symbols to be exported from a module must be defined with 'var'. The property access will work as previously for the time being, but please fix your code anyway.
