我在联想 G500 笔记本电脑上运行 Kubuntu 13.10。
我的问题与此类似： 如何重新映射 HP 笔记本电脑上的 F 键？
也就是说，我的 F1-F12 键被映射到某些特殊功能，只有按住 Fn 键才能恢复对标准 F1-F12 键的访问。 如何重新映射某些键或设备？
我想知道是否有办法将 Fx 重新映射到 Fn+Fx 或反之亦然。按照 #87043 的说明，我检查了我的 BIOS，没有选项可以切换 Fx/Fn 键功能。
通过联想的支持论坛进行谷歌搜索表明，支持此功能的 BIOS 更新正在进行中，但没有迹象表明何时完成。
使用 xev，我能够看到按下 F1-F12 时 X 看到的内容。有些会发送单独的键码，但有些会以某种方式映射到组合键或其他未知内容：
F1——XF86音频静音
F2——XF86音频音量降低
F3 - XF86 音量提高
F4-Alt_L + F4
F5 - F5
F6 - 禁用 touchapd，不能完全理解 xev 告诉我发生了什么，如果禁用则重新启用（内核日志显示这些具有明确定义的扫描码，未分配给任何键码）
F7 - XF86WLAN
F8——Alt_L + Ctrl_L + Tab
F9 - 关闭 LCD 背光，xev 什么也看不见
F10-Super_L + p
F11 - XF86Mon亮度降低
F12 - XF86Mon亮度提高
按照此页面上的说明进行操作： 如何重新映射某些键或设备？
我重新映射了所有具有明确键码的键（F1、F2、F3、F5、F7、F11、F12），但 F4、F6、F8、F9、F10 键仍然无法正常工作。
这尤其令人沮丧，因为 F4、F6、F9 现在分别会关闭当前窗口、触摸板和屏幕。
任何有关将这些键重新映射到其正确功能的帮助都将不胜感激！ -Anatoli
