我在 HP Spectre x360 上运行 Kubuntu 15.10,它的显示屏内置了非 Wacom 有源数字化仪。我使用双按钮触控笔,但第二个按钮不起作用。按下xinput
按钮时,我无法显示任何状态变化;似乎 X 根本看不到它。确实evtest
看到了一个事件,但它将按钮报告为BTN_TOOL_RUBBER
而不是适当的BTN_STYLUS2

触控笔没有橡皮擦尖。input-kbd
给了我扫描码并显示了同样的问题:

尝试使用input-kbd
分配新地图时会出现“扫描代码超出范围”错误。直接使用setkeycodes d003c 332
也不起作用(USB 键盘错误)。
更新:我尝试通过 udev 向 /etc/udev/hwdb.d 添加自定义 hwdb 文件来修复此问题,但似乎没有任何效果。
$ cat /etc/udev/hwdb.d/61-touchscreen-quirks.hwdb

我在这里做错了什么,或者,有什么更好的方法可以做到这一点?
答案1
我终于能够BTN_STYLUS2
使用重新映射扫描码ir-keytable
。命令是:
sudo ir-keytable --device /dev/input/event8 --set-key 0xd003c=BTN_STYLUS2
但是,虽然我看到扫描码已成功重新绑定,但按钮仍然无效。evtest
按下按钮时不再报告任何事件。
在此之前,按下该按钮时没有MSC_SCAN
报告任何事件evtest
,但其他按钮和笔触摸都报告了扫描码。当时我觉得这不过是个奇怪的怪癖,但现在看来该按钮确实没有生成扫描码。那么,它是如何evtest
报告键码事件的呢?这真难倒我了,现在我把它归咎于内核错误。
最后,我只是拼凑了一个 bash 脚本来监视evtest
事件BTN_TOOL_RUBBER
并模拟右键单击xdotool
:
#!/bin/bash
# Find the input device number.
devicename="ELAN Touchscreen Pen"
numevents=$(ls /dev/input | grep -c event*)
for ((devnr=0;devnr<$numevents;devnr++)); do
input-kbd $devnr | grep -q "$devicename"
if [[ $? == 0 ]]; then
break
fi
done
# Listen for BTN_TOOL_RUBBER events.
evtest /dev/input/event$devnr | while read line; do
for value in {0..1}; do
echo $line | grep -q "type 1 (EV_KEY), code 321 (BTN_TOOL_RUBBER), value $value"
if [[ $? == 0 ]]; then
case $value in
0) xdotool mouseup 3 ;;
1) xdotool mousedown 3 ;;
esac
fi
done
done
无论如何,这基本上给了我想要的基本功能。它并不完美:鼠标释放事件仅在笔离开接近度时发生,而不是在按钮释放时发生(这是BTN_TOOL_RUBBER
在 中报告键盘释放事件的时候evtest
),但它工作得很好,所以我不会尝试调试内核。
答案2
我的 Surface Pro 3 也遇到了同样的问题,并通过以下方式解决:
https://forums.linuxmint.com/viewtopic.php?f=59&t=312005&p=1762496#p1762496
在设备列出后xsetwacom list device
,您可以轻松地重新映射按钮xsetwacom
。
答案3
这个是一年前的文件,但我想说的是,你的hwdb
文件几乎是正确的。但是:
- 右边必须是十进制,而不是十六进制,所以使用
332
not14c
。 - 左侧来自
evtest
notinput-kbd
(不要问,因为我真的不知道)。具体来说,它来自紧接在事件(或错误映射的键)之前的行value
中的字段。MSC_SCAN
BTN_TOOL_RUBBER
就我的情况来说:
type 4 (EV_MSC), code 4 (MSC_SCAN), value d0045
所以我的完整hwdb
文件是:
evdev:input:b0003v04F3p21D0*
KEYBOARD_KEY_d0045=332
sudo udevadm hwdb --update
sudo udevadm trigger /dev/input/event*
- 重启。
