================================================================================

一直忘了要貼這篇,會寫上面這一系列探索紀錄,是因為這篇的緣由,所開端的 :p
結果因此也有應用上這一系列的探索紀錄,來探索相關的議題

================================================================================

# 關於「gnome-shell」啟動「ibus-daemon」

================================================================================

## 緣起

因為發現開機後,有執行「fcitx」,也有執行「ibus」。
所以覺得「ibus」好像不是經過「im-config」的機制。

所以做了點探索,有些還沒研究透徹。

以下只是稍微紀錄,目前探索到的部份。

================================================================================

## 探索開始

執行


$ ps aux | grep ibus



顯示


user       1202  0.0  0.1 377232  9696 tty1     Sl   11:43   0:00 ibus-daemon --xim --panel disable
user       1211  0.0  0.1 296652  8300 tty1     Sl   11:43   0:00 /usr/lib/ibus/ibus-dconf
user       1213  0.0  0.2 374576 23616 tty1     Sl   11:43   0:00 /usr/lib/ibus/ibus-x11 --kill-daemon
user       1486  0.0  0.1 220760  8332 tty1     Sl   11:43   0:00 /usr/lib/ibus/ibus-engine-simple





並且也發現「/usr/share/im-config/data/21_ibus.rc」


$ grep ibus-daemon /usr/share/im-config/data/21_ibus.rc -n



顯示


6:IBUS_ENABLE_SYNC_MODE=0 /usr/bin/ibus-daemon --daemonize --xim --address 'unix:tmpdir=/tmp/ibus'



上面啟動的參數,對照剛剛找到正在執行的「ibus-daemon --xim --panel disable」不相同。
以前在「另一篇」,有討論過這部份的議題。

而且我也有執行「im-config -n fcitx」,所以在我環境的「~/.xinputrc 」是「run_im fcitx」
並且「fcitx」也有在執行。

所以我才會聯想到「ibus-daemon」在「Ubuntu 17.10」不是經由「im-config」的機制啟動的。

於是執行「pstree」,發現到「ibus-daemon」是在「gnome-shell」底下啟動的。

然後先執行下面的指令,找到「gnome-shell」的「pid」。


$ ps aux | grep gnome-shell



顯示


user       1041 14.9  7.1 3849340 580588 tty1   Rl+  11:43   0:00 /usr/bin/gnome-shell
user       1197  0.0  0.1 621636 15904 ?        Sl   11:43   0:00 /usr/lib/gnome-shell/gnome-shell-calendar-server




接著執行下面指令,只看「gnome-shell」底下的。


$ pstree -p 1041



顯示


gnome-shell(1041)─┬─ibus-daemon(1202)─┬─ibus-dconf(1211)─┬─{ibus-dconf}(1214)
                  │                   │                  ├─{ibus-dconf}(1215)

                  │                   │                       └─{ibus-engine-sim}(1489)
                  │                   ├─{ibus-daemon}(1208)
                  │                   └─{ibus-daemon}(1209)




================================================================================

## 探索「gnome-shell」

執行


$ apt-get source gnome-shell



會下載下面三個檔案

* gnome-shell_3.26.1-0ubuntu5.debian.tar.xz
* gnome-shell_3.26.1-0ubuntu5.dsc
* gnome-shell_3.26.1.orig.tar.xz

並且解開到「gnome-shell-3.26.1」這個資料夾。

執行上面這個步驟的前置作業,請參考「#24」。


執行下面指令,用「ibus-daemon」當關鍵字,在「gnome-shell-3.26.1」這個資料夾,找尋相關的檔案。


$ grep 'ibus-daemon' gnome-shell-3.26.1/* -R -n



顯示

gnome-shell-3.26.1/js/ui/status/keyboard.js:979:                    ibusManager.activateProperty(item.prop.get_key(),




執行


$ grep IBusManager gnome-shell-3.26.1/* -R -n



顯示


gnome-shell-3.26.1/js/misc/ibusManager.js:33:function getIBusManager() {
gnome-shell-3.26.1/js/misc/ibusManager.js:35:        _ibusManager = new IBusManager();

================================================================================

根據上面找到「gnome-shell-3.26.1/js/misc/ibusManager.js」這個檔案

執行


$ grep "'ibus-daemon'" gnome-shell-3.26.1/js/misc/ibusManager.js -A 6 -B 3



顯示



    _spawn: function() {
        try {
            Gio.Subprocess.new(['ibus-daemon', '--xim', '--panel', 'disable'],
                               Gio.SubprocessFlags.NONE);
        } catch(e) {
            log('Failed to launch ibus-daemon: ' + e.message);
        }
    },




還記得一開始,找到正在執行的「ibus-daemon --xim --panel disable」,
對照「['ibus-daemon', '--xim', '--panel', 'disable']」這一段。

* https://people.gnome.org/~gcampagna/docs/Gio-2.0/Gio.SubprocessFlags.html

================================================================================


## 範例一

產生一個檔案「start-ibus-daemon.js」,內容填入如下


#!/usr/bin/env gjs

const Gio = imports.gi.Gio;
const System = imports.system;

let IBus = null;
try {
    IBus = imports.gi.IBus;
} catch (e) {
    IBus = null;
    log(e);
}

log(IBus);

if (IBus == null) {
    System.exit(1);
}


print('IBus.MAJOR_VERSION:', IBus.MAJOR_VERSION);
print('IBus.MINOR_VERSION', IBus.MINOR_VERSION);


try {
    Gio.Subprocess.new(
        ['ibus-daemon', '--xim', '--panel', 'disable'],
        Gio.SubprocessFlags.NONE
    );
} catch(e) {
    log('Failed to launch ibus-daemon: ' + e.message);
}



執行下面指令,將「start-ibus-daemon.js」設為可執行


$ chmod u+x start-ibus-daemon.js



執行


$ ./start-ibus-daemon.js



顯示


Gjs-Message: JS LOG: [object GIRepositoryNamespace]
IBus.MAJOR_VERSION: 1
IBus.MINOR_VERSION 5
current session already has an ibus-daemon.



遇到這樣的情形,表示「ibus-daemon」已經在執行了,
只要把 「ibus-daemon」這個「process」給「kill」。
再執行「start-ibus-daemon.js」就不會出現上面的紅色字了。

從最上面一開始執行「ps aux | grep ibus」找到「ibus-daemon」的「pid」是「1202」。

所以執行下面指令


$ kill -9 1202



然後再執行


$ ./start-ibus-daemon.js



最後再執行「ps aux | grep ibus」確認,應該可以看到「ibus-daemon」的「pid」有所不同。


================================================================================

## 範例二

產生一個檔案「start-gedit.js」,內容填入如下


#!/usr/bin/env gjs

const Gio = imports.gi.Gio;

try {
	Gio.Subprocess.new(
		['gedit'],
		Gio.SubprocessFlags.NONE
	);
} catch(e) {
	log('Failed to launch gedit: ' + e.message);
}




執行下面指令,將「start-gedit.js」設為可執行


$ chmod u+x start-gedit.js



執行


$ ./start-gedit.js



就會開啟「gedit」。

================================================================================

## 範例三

產生一個檔案「gedit-open-profile.js」,內容填入如下


#!/usr/bin/env gjs

const Gio = imports.gi.Gio;

try {
	Gio.Subprocess.new(
		['gedit', '/etc/profile'],
		Gio.SubprocessFlags.NONE
	);
} catch(e) {
	log('Failed to launch gedit: ' + e.message);
}




執行下面指令,將「start-gedit.js」設為可執行


$ chmod u+x start-gedit.js



執行


$ ./start-gedit.js



就會使用「gedit」開啟「/etc/profile」這個檔案。

# 關於「fcitx-chewing」

================================================================================

## 安裝步驟和設定步驟

關於這些操作步驟,可以參考「#17 回覆: 裝了 ubuntu 16.04 lts 64位元版 一直無法輸入中文」。


## 注意事項

在「Ubuntu 17.10」,

* 我一開始還是按照上面那篇我紀錄的步驟卻安裝「fcitx」,一開始登出登入,或是重開機,
發現到「fcitx」有在執行,但是卻沒有顯示在「appindicator」那。
所以我就把「fcitx」「kill」掉,然後執行「fcitx」,就會顯示在「appindicator」。
然後重開機幾次還是不會顯示在「appindicator」。
但是後來我也不曉得做了什麼動作,結果現在就正常了。
我有嘗試看看能不能重現,把一些相關的設定檔「~/.config/fcitx/」砍掉,再測,
結果還是一樣開機,「fcitx」沒有顯示在「appindicator」那,
後來也是不曉得做了什麼動作,結果現在就正常了。
我也沒啥頭緒,無法抓個準,了解那個關鍵因素是在哪裡。
但目前是正常的,我也沒再去測試,探究是啥原因了。

* 目前還是有可能會碰到的狀況是,可能是登出,登入後個幾次,有可能「fcitx」並沒有執行,或是有執行,沒顯示在「appindicator」那
這時候只要手動去執行「fcitx」,就可以啟動了。


================================================================================

以上提供參考,因為還是有可能雖著後來的更新,未來這樣的狀況可能就會排除了。

# 關於「Gio.Settings」

================================================================================

延續下面這三篇提到關於「gsettings」的概念。

* 「#7 回覆: Ubuntu Linux 17.10 螢幕鎖定失效」(關於「gsettings schema」)
* 「#8 回覆: Ubuntu Linux 17.10 螢幕鎖定失效」(關於「gsettings schema override」)
* 「#9 回覆: Ubuntu Linux 17.10 螢幕鎖定失效」(關於「compile schemas triggger」)

以及下面這篇裡面,有紀錄使用「Gio.Settings」的範例。

* 「#10 回覆: Ubuntu Linux 17.10 螢幕鎖定失效」(探索「螢幕鎖定按鈕」顯示或隱藏的實做原始碼)

最後參考這篇

*「#34」 (如何透過安裝套件的方式,安裝額外的「gnome-extension」)

裡面我有提到一個套件「gnome-shell-extension-shortcuts」。

可以執行下面指令,下載套件下來探索


$ apt-get download gnome-shell-extension-shortcuts



會下載一個檔案「gnome-shell-extension-shortcuts_1.1.0-1_all.deb」。

執行下面指令,解開「gnome-shell-extension-shortcuts_1.1.0-1_all.deb」這個檔案


$ dpkg -x gnome-shell-extension-shortcuts_1.1.0-1_all.deb gnome-shell-extension-shortcuts



執行


$ tree gnome-shell-extension-shortcuts



顯示

11 directories, 13 files




初步看的時候,發現這個「gnome-shell-extension-shortcuts」有自帶一個「schemas」資料夾,
並且裡面有放置「gschemas.compiled」這個檔案。
並不是在上面文章提到的「/usr/share/glib-2.0/schemas/」。

因此研究了一下「convenience.js」這個檔案裡面的「function getSettings」的實作。

改寫了一個範例,放在「GitHub」上面,請搭配「說明一」和「說明二」,還有上面提到的概念文章。

其他還有一些探索過程中,寫下來的範例,可以從「這裡」列的順序來探索。

以上提供參考,也許對這部份想要深入探索的人,能有一個探索的起點。

報告完畢。

# 關於「Ubuntu flavours」和 「MetaPackages」

================================================================================

city 寫到:
新桌面版本「UBUNTU BUDGIE」:
預設的瀏覽器是chromium, firefox是另外下載使用
桌面右上角有個月亮,可設定夜間模式


歡迎您繼續分享您使用上的心得,感恩

有個疑問,就是「夜間模式」它的功用是什麼?您能否再多說點?
還是說我自己去測試,就會了解了,我還沒去測,只是先舉手發問。



這個桌面環境的操作,初步試用,我也蠻喜歡的,不過我目前也還沒深度去探索,
目前有很多桌面環境可以選擇了,沒有太多時間,所以有的只能先在「VirtualBox」稍微開起來簡單測試欣賞。 Orz...

對我來說,主要care的點就是

如何快速找到尚未開啟的程式」和「已經開啟的程式」。

* 關於「尚未開啟的程式」,若是透過「開始功能表」,在那需要有「Search」的功能,舉例「XFCE / Whisker Menu」,
有些桌面環境也有類似的選單。
而「Ubuntu Budgie」也是有。
* 關於「已經開啟的程式」,需要可以容易的切換,常見的就是在「taskbar」或「dock」如何呈現和排序。
進一步再搭配「workspace」。

當然也有其他的操作模式,歡迎其他人可以來分享。

後記:
稍微測試了一下「Ubuntu Mate 17.10」,發現它可以切換不同的「呈現配置(Panel Layouts)」。
開啟「Mate Tweak」,在「Panel」那個頁籤,
在「Panels」那個選項,有很多配置可以選擇。
「Select a panel layout to change the user interface」。


在「Xfce」則有「Xfce Panel Switch」。

================================================================================

雖然也可以同時安裝不同的桌面環境在同一個系統,登入的時候,選擇不同的登入Session就可以了,
不過我現在比較少這樣嘗試了,
因為通常我只有登入某一個,就很少切換到另一個了。

可以執行下面指令,初步找到有那些桌面環境相關「MetaPackages


$ apt-cache search '\-desktop$'

================================================================================

以「ubuntu-budgie-desktop」為例

然後在執行下面指令,觀看該套件的相關資訊


$ apt-cache show ubuntu-budgie-desktop



或是執行下面指令,過濾出「Depends:」開頭的那行


$ apt-cache show ubuntu-budgie-desktop | grep '^Depends:'



================================================================================

以「ubuntu-desktop」為例

執行


$ apt-cache show ubuntu-desktop




執行


$ apt-cache show ubuntu-desktop | grep '^Depends:'




執行


$ apt-cache showsrc ubuntu-desktop




執行


$ apt-cache showsrc ubuntu-desktop | grep '^Binary:' -B 3



顯示


Package: ubuntu-meta
Format: 3.0 (native)
Binary: ubuntu-minimal, ubuntu-standard, ubuntu-desktop, ubuntu-server



表示「ubuntu-meta」這個「Source Package」,
拆成四個「Binary Package」如下列表

* ubuntu-minimal
* ubuntu-standard
* ubuntu-desktop
* ubuntu-server


================================================================================

參考「Ubuntu 17.10 (Artful Aardvark) Release Notes / Ubuntu Desktop

以前的「Ubuntu GNOME」,現在就沒有繼續了。

Ubuntu 17.10 (Artful Aardvark) Release Notes 寫到:

* The Ubuntu GNOME flavor has been discontinued. If you are using Ubuntu GNOME, you will be upgraded to Ubuntu. Choose the Ubuntu session from the cog on the login screen if you would like the default Ubuntu experience.



然後有兩個套件「vanilla-gnome-desktop」和「gnome-session」。

Ubuntu 17.10 (Artful Aardvark) Release Notes 寫到:

* Install gnome-session and choose GNOME from the cog on the login screen if you would like to try a more upstream version of GNOME. If you'd like to also install more core apps, install the vanilla-gnome-desktop metapackage.



執行


$ apt-cache show vanilla-gnome-desktop



執行


$ apt-cache show gnome-session




================================================================================

我目前對「Ubuntu Budgie 17.10」唯一的發現,只有「Terminal」預設是採用「Tilix
我有紀錄在「#40」,以前我在使用「Xubuntu 16.04」的時候,有去官網下載來使用。


================================================================================

另外題外話,好像有看到某篇網路上的文章,「Ubuntu Mate 17.10」這個版本有很多新的特色,還沒去實際嘗試。
也歡迎有試用的人,可以來分享。

後記:
除了上面「呈現配置(Panel Layouts)」的後記,
另外還有一個「HUD」的功能,概念上應該是源自「Unity 7」的功能
不過我以前沒在用「Unity」,所以就不曉得有這樣的功能。
需要在有「Global Menu」的「呈現配置」,當開起某個程式,按下「Alt」,就可以用關鍵字,查詢選單的選項,和執行。

更多請參考「https://ubuntu-mate.org/blog/ubuntu-mate-artful-final-release/」。

感謝!

寫感想文,這個要依照您自己的時間和意願拉,我沒有勉強的意思,我也勉強不來 :p

我通常都是有人問,有碰觸過相關的議題,才有靈感寫,
沒碰觸過的議題,我是從別人問的關鍵字,能有個契機去開頭探索,如此而已。
有時候沒啥進展,沒啥可紀錄的,就沒回覆,或貼出來了。

所以關於寫感想文這個提議,造成您有壓力!歹勢啦!


再次感謝您的分享!

## 如何透過「gsettings」設定「Night Light」的相關參數

================================================================================

city 寫到:
感謝samwhelp大
不好意思,我只是一般使用者,不會寫感想文
我是live usb開機試用,覺得不錯才貼文告知大家有這個新桌面版本
右上角月亮好像是調色溫,晚上可調暗一點,有作用
不像ubuntu到現在調亮度的功能都只是擺好看的


執行


$ grep 'gnome-control-center display' /usr/share/applications/* -R



顯示


/usr/share/applications/gnome-display-panel.desktop:Exec=gnome-control-center display




想要先確認一件事情
(後記:寫完這篇後,我開始測「Ubuntu Budgie 17.10」,那個「月亮按鈕 / Display Settings」也是「gnome-control-center display」,應該是同樣的機制,可以追「budgie-core」的程式碼)

您提到的功能,在「Ubuntu 17.10」,
是不是在「$ gnome-control-center display」這裡有一個欄位「Night Light」。
按下之後,會跳出另一個標題為「Night Light」新視窗。
然後在新視窗一樣有個欄位「Night Light」,將它設定為「On」。
在新視窗另一個欄位「Schedule」,可以選「Manual」。
然後下面有兩個時間的欄位就可以調整,可以調整「From」和「To」,可以調整讓現在的時間,是在這個區間內,就會有作用了。
舉例,現在時間是「17:30」,我調整「From」到「17:00」,而原本「To」就是「6:00」。
至於最下面那個顏色條,我不能移動調整,這個我還沒弄懂。

以下只是初步測試,有些我還不是很了解。

================================================================================

接下來依照之前一個討論案例的模式


執行下面指令,下載「gnome-control-center」的「Source Package」。


$ apt-get source gnome-control-center




然後可以在「gnome-control-center-3.26.1/panels/display/cc-night-light-dialog.c」這個檔案,
找到一個關鍵字「org.gnome.settings-daemon.plugins.color」。


執行


$ grep 'org.gnome.settings-daemon.plugins.color' gnome-control-center-3.26.1/* -R



顯示


gnome-control-center-3.26.1/panels/display/cc-night-light-dialog.c:#define DISPLAY_SCHEMA   "org.gnome.settings-daemon.plugins.color"
gnome-control-center-3.26.1/panels/display/cc-display-panel.c:  priv->settings_color = g_settings_new ("org.gnome.settings-daemon.plugins.color");
gnome-control-center-3.26.1/panels/color/cc-color-common.h:#define GCM_SETTINGS_SCHEMA             "org.gnome.settings-daemon.plugins.color"
gnome-control-center-3.26.1/panels/color/cc-color-panel.c:#define GCM_SETTINGS_SCHEMA  




================================================================================

接下來直接透過「gsettings」來測試。



$ gsettings list-recursively | grep 'org.gnome.settings-daemon.plugins.color'



顯示


org.gnome.settings-daemon.plugins.color night-light-schedule-automatic false
org.gnome.settings-daemon.plugins.color priority 0
org.gnome.settings-daemon.plugins.color recalibrate-display-threshold uint32 0
org.gnome.settings-daemon.plugins.color night-light-last-coordinates (91.0, 181.0)
org.gnome.settings-daemon.plugins.color night-light-enabled true
org.gnome.settings-daemon.plugins.color night-light-schedule-from 17.0
org.gnome.settings-daemon.plugins.color night-light-schedule-to 6.0
org.gnome.settings-daemon.plugins.color night-light-temperature uint32 4000
org.gnome.settings-daemon.plugins.color recalibrate-printer-threshold uint32 0
org.gnome.settings-daemon.plugins.color active true



所以可以看到

* night-light-schedule-from 17.0
* night-light-schedule-to 6.0
* night-light-temperature uint32 4000

然後接下來嘗試來調整「night-light-temperature



執行


$ gsettings set org.gnome.settings-daemon.plugins.color night-light-temperature 5000



執行


$ gsettings set org.gnome.settings-daemon.plugins.color night-light-temperature 6000



執行


$ gsettings set org.gnome.settings-daemon.plugins.color night-light-temperature 3000



您會發現螢幕是有變化的。

================================================================================

執行下面指令,還原成預設值


$ gsettings reset org.gnome.settings-daemon.plugins.color night-light-temperature



執行下面指令,觀看目前的設定值


$ gsettings get org.gnome.settings-daemon.plugins.color night-light-temperature



顯示


uint32 4000



================================================================================

執行下面指令,觀看「/usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.color.gschema.xml 」這個檔案的內容。


$ cat /usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.color.gschema.xml

## 關於「Night Light 設定」的「Daemon」

================================================================================

延續「#48」。

了解到可以透過下面指令,讓螢幕有變化。


$ gsettings set org.gnome.settings-daemon.plugins.color night-light-temperature 3000



不過「gsettings」應該只有修改值。

所以推測有另一個「daemon」在跑,監聽著「org.gnome.settings-daemon.plugins.color night-light-temperature」是否有變化,
有變化,就會根據該變化,作相對應的動作。


================================================================================

先來作一個小實驗,來描繪這樣的概念,
我之前在「#10 回覆: Ubuntu Linux 17.10 螢幕鎖定失效」這篇,也有做這樣的小實驗。

先在「Terminal A」,執行下面指令,


$ gsettings monitor org.gnome.settings-daemon.plugins.color night-light-temperature



然後另外開啟一個「Terminal B」,執行下面指令,


$ gsettings set org.gnome.settings-daemon.plugins.color night-light-temperature 3000



可以看到「Terminal A」,會出現下面的訊息。


night-light-temperature: uint32 3000



然後在「Terminal B」,執行下面指令,


$ gsettings reset org.gnome.settings-daemon.plugins.color night-light-temperature



可以看到「Terminal A」,會出現下面的訊息。


night-light-temperature: uint32 4000



================================================================================

接下來,透過上一篇提到的「/usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.color.gschema.xml」,
來找到相關的「Daemon」套件和原始碼。

以下探索開始。

================================================================================

執行


$ dpkg -S /usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.color.gschema.xml



顯示


gnome-settings-daemon-schemas: /usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.color.gschema.xml
