当您使用超级+空格切换语言时，Numlock指示灯将熄灭
每当我将语言从英语切换到另一个时，我的Num Lock指示灯会熄灭，但我仍然可以使用它。 我知道这是一个Ubuntu 14.04 LTS错误。 但它有任何补丁吗？
错误报告在这里 。 Egmont Koblinger写了一个补丁 （见错误报告的第22条评论）。 我不切换语言，所以我没有测试它，但其他用户报告它的工作原理。
使用以下步骤下载并重建xorg-server（如Egmont在其评论中所述）：
sudo apt-get install build-essential fakeroot dpkg-dev mkdir build cd build apt-get source xorg-server sudo apt-get build-dep xorg-server cd xorg-server-1.15.1 cp ~/Downloads/xorg-server-xkb-numlock.patch debian/patches/ # replace Downloads appropriately echo xorg-server-xkb-numlock.patch >> debian/patches/series dpkg-buildpackage -rfakeroot -b cd .. sudo dpkg -i xserver-common_1.15.1-0ubuntu2_all.deb xserver-xorg-core_1.15.1-0ubuntu2_amd64.deb 另请参阅dimitronic对该报告的评论＃27的替代方法，尽管它是一个脚本，而不是您请求的补丁。 我在下面复制了它：
1)mkdir ~/keyfix ; cd ~/keyfix 2)open a file show_layout.sh and copy and paste this: " setxkbmap -print | grep xkb_symbols | awk '{print $4}' | awk -F"+" '{print $2}' " (without the first and the last ") 3)open a file keyfix.sh and copy and paste this: s=0 s1=0 while test "1" == "1" do s=`$HOME/keyfix/show_layout.sh` sleep 0.001s if test "$s" != "$s1" then numlockx off numlockx on #if test "$s" == "alt_layout" #then #xset led named "Scroll Lock" #else #xset -led named "Scroll Lock" #fi fi s1=`$HOME/keyfix/show_layout.sh` if test "$s" != "$s1" then numlockx off numlockx on #if test "$s" == "alt_layout" #then #xset led named "Scroll Lock" #else #xset -led named "Scroll Lock" #fi fi sleep 0.01s done ******************** if you want to turn on scroll lock when you use alternative layout, remove the #'s and change alt_layout to your alternative layout ie "gr" or "us" ************************** 3)open a file disown_easy.sh and copy and paste this: #!/bin/bash $1 & P=`which $1` disown `pidof ${P}` 4)open a file run-keyfix and copy and paste this: $HOME/keyfix/disown_easy.sh $HOME/keyfix/keyfix.sh 5) open a terminal and type: chmod +x ~/keyfix/* ; sudo cp ~/keyfix/run-keyfix /usr/bin/ 6)make the script run-keyfix to run on startup! (go to startup applications and add it) THIS IS NOT A SOLUTION! THIS IS A STUPID FIX! *don't use these scripts to make weapons!
