我有两个目前在 SLES 12 SP3 中工作的触摸屏设备。我想做的是让 Xephyr 在第二台显示器上运行一个单独的（基本上是多座的）窗口，它有自己的独立于主屏幕的触摸屏。
问题是，我似乎无法让 Xephyr 抓取/允许触摸。我正在使用的命令如下：
Xephyr -ac -br -noreset -screen 1280x800 :1 -mouse evdev,,/device=/dev/input/by-id/usb-ILITEK_ILITEK-TP_V06.00.00.02-if01-event-mouse
/dev/input/by-id/ 的输出：

我已经通过“ILITEK_ILITEK-TP_V06.00.00.02”读取了触摸事件，但实际的“鼠标按下”（又名点击）仍未注册，似乎没有任何内容可供选择。
