光标再次向后移动

Question

我的光标在向后移动。上次我被建议安装：sudo apt install gnome-tweaks

我认为它工作了一段时间，但现在不行了，我仍然遇到这个问题。我尝试再次安装它，并收到以下消息：

$ sudo apt install gnome-tweaks
Reading package lists... Done

gnome-tweaks is already the newest version (3.28.1-1).
The following package was automatically installed and is no longer required:
  libapache2-mod-php8.0
Use 'sudo apt auto remove to remove it.
0 upgraded, 0 newly installed, 0 to remove and 109 not upgraded.

我没有删除它。请指导我。
