在 KDE Plasma 桌面环境无法使用 TIM，提示：
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 20 (X_GetProperty)
Resource id in failed request: 0x0
Serial number of failed request: 10
Current serial number in output stream: 10

需要先安装 gnome-settings-daemon 并启动 /usr/lib/gsd-xsettings，本文以 Arch Linux 为例。
1# pacman -S gnome-settings-daemon

3$ /usr/lib/gsd-xsettings &
可以将 /usr/lib/gsd-xsettings 命令添加到 KDE 设置的自动启动中。
