问题表现如下：我离开电脑，大约 15 分钟后回来发现屏幕变黑并且电脑已锁定（如预期）。我点击空格键将其唤醒，成功了，显示锁定屏幕，我可在此输入密码。然后图标旋转约半圈然后停止。然后我可以无限期等待，锁定屏幕不会继续。鼠标光标仍然有效，但其他任何功能均无响应。我可以通过切换到另一个 tty 并重新启动 gdm 服务来恢复，而无需重新启动，但这（如预期）会关闭所有打开的程序。
我尝试在 12:19 左右登录，所以这可能与“systemd-logind：暂停”日志有关。另一个可疑的事情是“电源按钮：设备已移除”，尽管我不确定这是否出乎意料。我已附上我的 syslog、hwifno 和 nvidia-smi 输出。
到目前为止，我尝试使用 Nouveau 驱动程序、使用 470 和 510 版本的 Nvidia 专有驱动程序，并禁用所有 Gnome shell 扩展。我还尝试禁用交换和休眠，以防休眠失败，我还根据另一个论坛上的提示禁用了安全启动。我在 Xorg 上使用无显示缩放，通过显示端口使用两个 4k 显示器。
另一件值得注意的是，这是戴尔预装的 Precision 5820，预装了 Ubuntu，因此它具有一些我找不到太多相关信息的戴尔“Matira”和“Somerville”软件包。
如果我遗漏了任何重要信息，请告诉我。

答案1
您可以尝试重新安装 lightdm 并重新启动
sudo apt autoremove lightdm --purge
sudo apt install lightdm
sudo reboot
如果不行的话，也重新安装 gdm3
sudo apt autoremove gdm3 --purge
sudo apt install gdm3
sudo reboot
