x 服务器在系统更新后无法启动

x 服务器在系统更新后无法启动

几个月后(自 2020 年 4 月起),我重新启动了系统。

就在重启之前,我更新了整个系统(内核、nvidia 驱动程序等),从那时起,x 服务器无法正常启动。

我日常使用的是 XDM + i3wm 组合。

和处的日志文件/var/log/xdm.log以及Xorg.n.log里面的日志文件都是空的~/.local/share/xorg

journalctl -b可以在此处找到最近一次启动()的输出http://sprunge.us/96m4nD

我不确定该如何处理这个问题。我试过

  • xorg.conf使用从头开始重新创建文件nvidia-xconfig
  • 删除并重新安装所有 nvidia+xorg 软件包
  • 尝试使用 sddm/lxdm 代替 xdm

任何帮助,将不胜感激!


如果我禁用 XDM 服务并回退到 getty shellstartx手动执行,则该命令只会显示默认输出,没有错误,但系统会冻结。

我也已启用debug-shell.servicesystemctl,但Ctrl++AltF#没有响应,因此我无法访问调试 shell。


编辑/更新

我猜只有当我设置了多头(多显示器)时才会出现问题。当我将辅助屏幕与 GPU 断开连接时,系统开始正常响应。

重新连接屏幕后,整个系统冻结。仍然不知道为什么会发生这种情况。

答案1

我不确定如何处理这个问题。

因此,systemd 尝试启动 X-Window 显示管理器(启动 X 服务器并提供登录屏幕),检测到“堆栈粉碎”,并终止该过程。

这意味着您的更新在驱动程序中引入了某些严重失败的东西,或者 systemd 过于急于终止某些东西。

尝试将与之前版本相关的所有 X 降级(您有更新日志可以帮助您)。看看它是否有效。如果有效,则可能是您升级的内容中存在一些错误。

相反,尝试将 systemd 降级到您之前的版本。如果成功,systemd 现在会将 X 驱动程序中的有效行为检测为不良行为,因此请针对 systemd 提交错误报告。
