我的联想 Ideapad Flex 5 触摸屏无法使用，手写笔也无法使用。我尝试按照以下答案操作https://askubuntu.com/a/1234852/928890但它不起作用。针对此问题还有其他选择吗？

答案1
我刚买了一台 IdeaPad Flex 5 14"，遇到了同样的问题。我成功编译并加载了 wacom 和 wacom_w8001 模块，但没有帮助。
请注意，在我的系统上 - 与您的类似但与其他一些帖子不同，从未加载过任何 elan* 驱动程序。

另外，Xorg 日志中输出：

与其他产品一样，触摸屏在 Windows 10（双启动）上运行良好。我想说我们还没有一个好的可用驱动程序 - 到目前为止？
