我使用的是 Ubuntu MATE 22.04。今天登入後，我發現各個子系統都亂了。到目前為止我注意到：
無需點擊觸控板（無需簡單、雙擊或三次點擊）
Ctrl+ Alt+T不會開啟終端
Win+ ←//↑不會→向左/向右/最大化視窗對齊
Win+L不會再鎖定我的會話
桌面上出現回收站和計算機的圖標
桌面上的新圖示：
托盤上的圖標已更改並且托盤行為已更改（我必須右鍵單擊網絡才能獲取選項）
托盤上的新圖示：
將窗口拖到角落也不會再卡住
壁紙有時會被預設壁紙替換（但僅有時在重新啟動後）。
我注意到同一天進行了無人值守的升級。我的/var/log/apt/history.log有一些xorg無人gtk值守的升級（輸出如下）。
我繼續嘗試自行修復每個問題，但通常的“點擊”解決方案已經不起作用：我嘗試修改/usr/share/X11/xorg.conf.d/40-libinput.conf並添加下面的“點擊”行，即使在重新啟動後也不會執行任何操作。
Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "Tapping" "True"
EndSection
那麼，誰能看出什麼會影響這麼多不同的子系統呢？有沒有辦法恢復它？以下輸出/var/log/apt/history.log（編輯至最新和相關安裝）：
