[Windows 11] Quick Settings panel cannot be launched

 Windows 11 右下角的快速設定面板無法啟動

點右下角的 Wifi, 音量, 電池的圖示可以打開快速設定面板

或是按 [Win] + a 也可以打開快速設定面板

但在 Acer 筆電上常常會打不開...

找到這篇有提到如何重新設置 Settings Apps 的方法

https://www.elevenforum.com/t/reset-and-re-register-settings-app-in-windows-11.2411/

1.開啟 Power Shell

2.執行

Get-AppxPackage *windows.immersivecontrolpanel* | Reset-AppxPackage

3.重新啟動電腦

升級到 Debian 9 (Stretch) 後，Touchpad 設定在滑鼠與觸控板中消失了

 Debian 9 改用 xserver-xorg-input-libinput 取代 xserver-xorg-input-synaptics 了。
移除 xserver-xorg-input-synaptics 後，登出再登入，設定頁面就出現了。

colormake cause menuconfig unusable

My .bashrc have a alias for colormake

alias make=colormake

But when I want to do make menuconfig for kernel, the config menu can not display correctly.

Then I found the colormake cause that. It's too bad.

Package's state in the package list

aptitude 列出來的 package 列表中，前面開頭三個字元表示該 package 的狀態。例如：

idA    libsmbclient          

字元一表示 state
字元二表示 action
字元三表示 automatic

state 可以是：
v - virtual
B - broken
u - unpacked
C - half-configured
H - half-installed
c - removed, but config-files still present (ie, not purged)
i - installed
E - internal error ( should not happen)

action 可以是：
h - hold
p - purge
d - delete (remove)
B - broken
i - install
r - reinstall
u - upgrade
F - the available upgrade has been forbidden via "F"

字元三若出現 A，表示該 package 是因其它 package 的安裝的相依性而自動被安裝。

perl warning for setting locale failed

Can't set locale; make sure $LC_* and $LANG are correct!
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "en_US:en",
LC_ALL = (unset),
LC_TIME = "zh_TW.utf8",
LC_MONETARY = "zh_TW.utf8",
LC_MEASUREMENT = "zh_TW.utf8",
LC_NUMERIC = "zh_TW.utf8",
LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_ALL to default locale: No such file or directory

上面這情形發生在透過 ssh 連到遠端機器執行與 perl 相關的程式時所發生的。
古哥說下面這地方有解法
http://stackoverflow.com/questions/2499794/how-can-i-fix-a-locale-warning-from-perl

原因在於 /etc/ssh/sshd_config 中有一行設定

# Allow client to pass locale environment variables
AcceptEnv LANG LC_*

這表示 ssh client 可以把它的 locale 環境變數傳給 ssh server。
但若 ssh server 中沒有安裝該 locale，就會出現上面這樣的訊息。

所以解法有幾個：
從 server 端解：
1. 安裝該 locale

$ sudo dpkg-reconfigure locales

2. ssh server 不要接收從 ssh client 傳來的 locale 環境變數

 # Allow client to pass locale environment variables
 # AcceptEnv LANG LC_*

從 client 解：
執行 ssh 時，強制設定 LANG 的環境變數為 C

$ LANG=C ssh user@remote_server
