Microsoft Ergonomic 7000 键盘 + 鼠标延迟

Microsoft Ergonomic 7000 键盘 + 鼠标延迟

我最近买了一个新的 Microsoft Ergonomic 7000 键盘。我开始将它与我的 Ubuntu 12.04 一起使用,但它总是滞后。我尝试更具体一点:

  • 即使 CPU 使用率较低,鼠标也会滞后。所谓“较低”,我指的是 Firefox 加载网页或打开 conky、gnome-terminal 等应用程序时。
  • 当 CPU 使用率较高时,键盘也会滞后,但我的意思是它会错过我的点击,所以我输入的内容不会稍后出现。

我到目前为止尝试过什么(但没有效果)?

  • 禁用自动暂停(echo -1 到 sys/bus/usb.../autosuspend)并在同一位置将级别设置为“on”。
  • 我尝试了几种视频驱动程序:Vesa、radeon、最新催化剂(以及催化剂测试版)

当我的键盘和/或鼠标出现延迟时,我尝试了另一个 USB 键盘,它工作正常,鼠标也一样。我也在另一台装有 Linux(Ubuntu、Arch、OpenSuse)的计算机上尝试了键盘和鼠标,出现了同样的问题,但在 Windows 上没有出现。

我尝试更换电池组,并更改适配器的频道。还尝试从其他 USB 端口使用适配器。同时,我可以使用任何其他无线鼠标。

我将 XkbModel 更改为“microsoft7000”,但没有解决任何问题。

关于硬件:

  • AMD A8 3870K -> Radeon HD6550D
  • 8 GB 内存
  • 4 GB 的交换空间(几乎从未使用过)

以下是我的电脑的详细信息:

向后移植的较新版本的显卡驱动程序fglrx解决了我的问题。我发现PPA X-更新提供这个。
