有在其他帖子评论相关问题，可能是评论的问题，好几天了没有看到有工作人员跟踪和反馈。新开一个帖子跟踪一下问题。

问题描述：

在输入打字的时候频繁有按键重复问题，比如打deepin，可能出现deeeeeeeepin等类似情况。无论中英文都会出现这种情况，中文更频繁一些。（看到其他帖子有人反馈是系统自带的搜狗输入法Deepin Next版的问题，但是我尝试删除卸载相关应用及组件后依然有类似问题）

系统信息：

版本：deepin 23 - ver: 23.1

uname: Linux Admin 6.12.20-amd64-desktop-rolling #23.01.01.23 SMP PREEMPT_DYNAMIC Thu Apr 10 19:56:14 CST 2025 x86_64 GNU/Linux

看其他人的反馈好像不只是23系统会有这个问题，其他也有。

已做的尝试：

调整设置里面的键盘设置，将重复延迟拉长。无用。

卸载搜狗输入法，并重置输入法，无用。

使用命令 xset -r r off 临时关闭按键重复功能，有效果，确实不会按键重复了，但是是假象，指标不治本。在输入的时候有时候会非常卡(卡顿其实是系统在执行重复按键的相关操作，只不过由于关闭了重复按键，虽然不会重复了，但是相关操作并没有避免执行，卡顿的过程其实就是在等待按键执行完重复)

已查阅的其他相关反馈：

键盘鼠标输入为用户高频操作，建议加急处理，出现的时候基本约等于系统不可用。愿deepin越来越好。

cat /proc/interrupts 看看中断的数据。

看起来从硬件发过来的信号就是有多个。

Bus 001 Device 002: ID 0b05:193e ASUSTek Computer, Inc. ROG FALCHION

刷新了下usb，然后切换了下键盘的USB插孔。

好像正常了，至少到目前为止看似正常了。。。。。

后续持续跟进，有异常会继续跟踪，没有异常会关闭该帖子。

结论：

疑似部分硬件不兼容？

键盘输入出现异常信号（如键码重复、异常触发），经过USB端口切换后问题暂时解决，这确实可能指向硬件兼容性问题。建议尝试以下方法排查下：
1、‌USB端口供电不足或接触不良‌，更换USB端口后问题缓解，说明原端口可能存在供电不稳定或物理接触问题。某些主板的不同USB端口可能由不同控制器管理，供电特性也有差异。
‌2、USB控制器冲突‌，某些USB 3.0控制器与特定设备存在兼容性问题，尝试在BIOS中禁用xHCI Hand-off或切换为USB 2.0模式测试。
