emacs升级29.x后鼠标滚轮无法识别

kyle · 2024 年4 月 3 日 15:42

大家好，这件事的起因是想在虚拟机中使用最新的emacs，编译后发现鼠标滚轮无法使用，所以进行如下测试：测试平台： Linux centos 7.9.2009，虚拟机VMware 17.0.0，鼠标罗技G502 测试步骤及结果：以下均使用emacs -Q启动

分别编译emacs29.3和29.1，滚轮无法使用
编译emacs28.1，滚轮可以使用
使用C-h k捕捉鼠标滚轮，发现28.x之前的可以捕捉到mouse-4 & mouse-5，29.x根本无法捕捉mouse-4 和mouse-5，但是可以捕捉到mouse-1 mouse-2 mouse-3

目前我已经没有什么思路去排查了，想请教一下大家还有没有其他的办法能debug的，想使用最新的emacs但奈何无能为力了，谢谢！

mouse 4 mouse 5? 是侧边功能键？

eusr · 2024 年4 月 4 日 00:42

是滚轮。

If you have a mouse with a wheel, the wheel events are commonly bound to either wheel-down or wheel-up, or mouse-4 and mouse-5, but that depends on the operating system configuration.

In general, legacy X systems and terminals (see Using a Mouse in Text Terminals) will report mouse-4 and mouse-5, while all other systems will report wheel-down and wheel-up.

C-h k 就滚轮识别不出来？其他都可以？

oldosfan · 2024 年4 月 4 日 03:18

请运行

xinput list --long

kyle · 2024 年4 月 7 日 03:22

是的，目前测试滚轮识别不出来。。不过侧边功能按键也识别不出来，但是侧边功能按键这个之前旧版本就不行，怀疑鼠标驱动，就没深究

前辈您好，我从shell中执行如您所说命令，返回结果如下，可否麻烦您帮忙解读一下这个结果能说明什么呢？感激不尽！

照理说驱动应该没问题，你虚拟机里面其他应用滚轮可以用，驱动就没有问题。我用的也是G502，要不你虚拟机里面下载个G HUB看看，看看按键宏有没有重新被定义

kyle · 2024 年4 月 8 日 14:17

g hub没有Linux的吧。。？我没找到哎，不过win下的g hub里我没对滚轮做绑定，使用的默认配置

oldosfan · 2024 年4 月 11 日 05:08

请运行 xinput test-xi2, 然后在弹出的窗口上滚动鼠标，再将输出发过来。

VMware 驱动有 bug，XI 2.1 环境下不应该只生成 emulated ButtonPress 和 ButtonRelease，尤其在有 aluator 的情况下。

cybertheye · 2024 年4 月 15 日 07:23

那大佬我有一个疑问，那为啥他其他应用可以用滚轮使用呀。如果驱动有问题，不应该所有的都不能用吗？专门针对emacs29？

XLBilly · 2024 年4 月 15 日 11:21

我这边也遇到了一个诡异的问题：在Windows上的Emacs 29可以使用USB鼠标滚轮滚动，但是用触控板双指滚动都识别成了向上滚动

kyle · 2024 年4 月 15 日 14:03

那请教一下我或许可以用什么办法来改善一下呢？没有滚轮的感觉真难受emmmm

oldosfan · 2024 年4 月 16 日 13:59

其他软件不像 Emacs 一样严格遵守 XInput 2 标准。

oldosfan · 2024 年4 月 16 日 14:00

可以编译时关闭 --with-xinput2

oldosfan · 2024 年4 月 16 日 14:00

这个 bug 已经修好了，建议升级至 emacs 29.2.

kyle · 2024 年4 月 16 日 15:39

好的感谢，我试一下~

很奇怪。。我忽然发现，我在root下滚轮就是好使的，但是user下不行；

我看了一下，29以下是以<mouse-4>/<mouse-5>来接收鼠标滚轮的事件的，但是29是以<wheel-up>/<wheel-down>来接收的，是不是这块有差异导致的呢？

kyle · 2024 年4 月 16 日 16:00

感谢大佬，configuration的时候加上就可以了！
