我已经在 Surface Pro 2 上使用 Ubuntu 几年了（从 14.04 开始），现在使用 16.04（内核 4.3+），开箱即用，基本运行正常。然而，有一件事让我很烦，那就是触控板按钮。
- 点击（触摸板上的任意位置）即可正常工作
- 按下物理点击按钮会弹出下面的覆盖层。某些应用程序（例如 nautilus、firefox、sublimetext）会记录点击，并且点击工作正常（尽管有覆盖层）。其他应用程序（例如 gimp）根本不响应点击（但会响应轻击）
- 单击并拖动也会弹出相同的覆盖，并且在某些应用程序中有效（例如 nautilus、firefox、sublimetext），但在其他应用程序中再次完全被忽略（例如 gimp）。
- 在任何情况下，双击（触摸板上的任意位置）按住并拖动均不起作用（无法单击和拖动）
- 两个手指滚动很好用
- 我在“设置”>“鼠标和触摸板”中没有触摸板选项卡
- 我正在使用 gnome 3 桌面
多年来我一直随身携带鼠标，只是为了能够在 gimp 中进行简单的点击和拖动，但我受够了！这个覆盖是什么意思？如何使用这个触控板在 gimp 中进行点击和拖动？
更新：从 xinput --test 中，我看到触摸板按钮也会发送按键事件。我该如何防止这种情况发生？

答案1
我在 Surface Pro 2 上安装 Fedora39 和 openSUSE 时遇到了这个问题，所以这仍然是所有发行版的驱动程序问题。要解决该问题，您可以重新映射触发密钥代码 201使用 udev 规则。我基本上遵循了archi wiki udev 教程，导致以下步骤（我猜可以应用不同的文件位置，硬件字符串等）：
- 使用 找出按键的扫描码
sudo evtest。在我的例子中，适用的硬件是/dev/input/event7：微软 SAM 键盘和扫描码70072 - 查找 udev 规则的硬件标识符，
sudo evemu-describe /dev/input/event7在我的例子中返回的是输入设备ID：总线0x03 供应商0x3eb 产品0x8209 版本0x111 sudo nano /etc/udev/hwdb.d/90-fixSurfaceKeyboard.hwdb使用以下输入 创建一个具有 udev 规则的新 hdwb 文件（相应地调整扫描代码和 HW ID）
请注意，总线 ID 等的十六进制代码必须大写，否则规则不会触发evdev:input:b0003v045Ep07A9e0111* KEYBOARD_KEY_70072=reserved- 重新加载所有内容：
sudo systemd-hwdb update sudo udevadm trigger - 检查输出是否
udevadm info <path to device e.g. /dev/input/event7>包含新规则，例如E：KEYBOARD_KEY_70072=保留如果不是这种情况，请重新启动您的机器并重新检查您的规则
扫描码现在被忽略并且左键单击按预期工作（X11 和 Wayland）
