我的 Dell Inspiron 7537 上的触摸屏偶尔会工作，大多数时候都无法工作。它通常在启动时无法被检测到，但只有在计算机挂起后恢复时才能被检测到。
当检测到时（暂停后），lsusb 会产生：
Bus 002 Device 010: ID 04f3:0201 Elan Microelectronics Corp. Touchscreen
以下是 dmesg 的输出，可能会有帮助，但我不确定它意味着什么：

从 LiveUSB 启动时，触摸屏在 Ubuntu Gnome、Ubuntu 16.04.03 LTS 上开箱即可使用，但在 Ubuntu 17.10、KDE Neon（过去几年的任何版本）或 Kubuntu 上则不行。这个问题我已经困扰我好几年了，我在这里和其他网站上搜索过答案，但都无济于事。有谁能帮忙吗？
