在登入畫面上輸入密碼後，會出現一個空白螢幕，其中有一個我們可以移動的滑鼠遊標，大約 2 分鐘後桌面就會顯示出來。這種情況不僅在啟動後發生，而且在我登出並嘗試重新登入時也會發生。幾天前我從 Ubuntu 20.04 升級到 22.04 後就開始發生這種情況。

這些 PCIe 日誌與 WiFi/藍牙相關。我嘗試在禁用兩者後登錄，但時間保持不變。 108 UID 屬於 lightdm。升級前我已經在使用 lightdm 了。
我嘗試過但沒有成功的事：
- 停用網路
- 使用 xfce 代替 lightdm
- 重新安裝MATE DE
- 建立另一個使用者帳戶
- 停用 VFS 守護程式
- 停用 Wifi/藍牙
- 打開了一個線程ubuntuforums.org
有人可以提出一個可能的原因嗎？
答案1
正如 @user1641501 所提到的，它看起來像是 nvidia 驅動程式問題。
我的nvidia-driver-515也遇到了同樣的問題，解鎖時間相當長。
我把它改成-510這樣後：
然後密碼檢查很快。
答案2
從 20.04 升級到 22.04 後，我遇到了同樣的問題。透過手動安裝 nvidia-driver-510 修復了該問題。之前使用的是建議的 nvidia-driver-470。
sudo apt-get install nvidia-driver-510
