Ubuntu 禁用设备的systemd服务无法启动

我为我的笔记本电脑lenovo x230平板电脑编写了禁用手指触摸的脚本。我想在启动时运行它，所以我使用systemd服务在启动时触发此脚本，但我无法手动启动此脚本。有什么帮助吗

剧本

[Unit]
Description=Turn-off finger touch

[Service]
Type=oneshot
ExecStart=/bin/sh -c "xinput set-prop 'Wacom ISDv4 E6 Finger touch' 'Device Enabled' 0"

[Install]
WantedBy=multi-user.target

下面是此服务的status命令的输出

systemctl status finger-touch-off.service

我也有同样的问题。在执行xinput之前，必须执行以下操作：

export DISPLAY=:0.0

systemd脚本将是：

[Unit]
Description=Turn-off finger touch

[Service]
Type=oneshot
ExecStart=/bin/sh -c "export DISPLAY=:0.0 && xinput set-prop 'Wacom ISDv4 E6 Finger touch' 'Device Enabled' 0"

[Install]
WantedBy=multi-user.target
