linux系统中universal access 图标的去除
前几天,不明所以的点开了右上角的universal access图标,并点击了其中的几个选项,导致笔记本键盘不可用。开机后插入的外接usb键盘可用(如果外接usb键盘在开机时就已经接入,仍然不可用)。在网上查了很多方法,都没有找到原因。后来就试着点击universal a
前几天,不明所以的点开了右上角的universal access图标,并点击了其中的几个选项,导致笔记本键盘不可用。开机后插入的外接usb键盘可用(如果外接usb键盘在开机时就已经接入,仍然不可用)。在网上查了很多方法,都没有找到原因。后来就试着点击universal access,并把打勾的选项全部去掉。问题解决。
于是想去除notification area(右上角区域)的universal access图标,方法有两种:
1、
按住alt-f2,输入gnome-keyboard-properties,弹出的对话框选择Accessibility,不要选中accessibility features can be toggled with keyboard(即不要打勾)即可去除.
2、
System-->Preferences-->Keyboard,弹出的对话框选择Accessibility,不要选中accessibility features can be toggled with keyboard(即不要打勾)即可去除.
也就是这两种方法只是调出对话框的方式不同,后续步骤都是相同的。
