信息
我刚刚构建了一个全新安装的 Ubuntu 20.04 LTS 系统。
我怀疑我的系统存在问题，因为它运行很慢并且经常冻结。
问题
检查日志文件，启动时几乎没有错误。

答案1
日志文件似乎表明了多种不同的错误。
- 第一个 (
kernel: [ 0.266759] Initramfs unpacking failed: Decoding failed) 是最严重的。尝试此修复（Linux Mint 基于 Ubuntu，因此它可能会起作用）。 - 第二个（
v4l2loopback: module verification failed: signature and/or required key missing - tainting kernel）与安全启动签名验证。这可能已禁用包含必要图形驱动程序的内核模块的加载，从而导致gnome-session（登录/会话管理器）和gdm3（显示管理器）失败。线索是错误消息gnome-shell[1333]: Failed to initialize accelerated iGPU/dGPU framebuffer sharing: Missing OpenGL ES extensions: (null) - 接下来，缺少库
libbd_mdraid.so.2，即 RAID 库组件，可以使用sudo apt install libblockdev-mdraid2 - 最后，从警告信息中可以看出，NetworkManager 无法管理网络接口
NetworkManager[1017]: <warn> [1606682194.6465] Error: failed to open /run/network/ifstate。这可能是由 VPN 软件 (systemd[1]: nordvpnd.socket: TCP_NODELAY failed: Operation not supported)引起的。
