字母 Q 停止在键盘上工作

Question

信Q并q停止在我的键盘上工作。 （我必须找到一个 ASCII 图表来复制并粘贴该字符。）我真的不知道发生了什么。

xev 产生以下输出。

KeymapNotify event, serial 37, synthetic NO, window 0x0,
    keys:  2   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0

I tested ever character on my keyboard with & without a shift in the command line.  They all seem to work fine.

因此，为了排除故障，我插入了 USB 键盘并q开始Q工作。有任何想法吗？
