Question

我编写了用于禁用笔记本电脑lenovo x230平板电脑手指触摸的脚本。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，但是我甚至无法手动启动此脚本。有什么帮助吗？

脚本

[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

以下是此服务的状态命令输出

systemctl status finger-touch-off.service
● finger-touch-off.service - Turn-off finger touch

我遇到了同样的问题。您必须在执行xinput之前执行此操作：

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

用于禁用设备的systemd服务无法启动
