如何在 X-server 關閉之前關閉所有應用程序？

我正在使用 debian 測試作業系統和 openbox WM。此外，我通過該文件啟動 X-server，該.xinitrc文件具有以下內容：

xrdb /home/morfik/.Xresources
exec ck-launch-session dbus-launch --sh-syntax --exit-with-session openbox-session

我在重新啟動系統時注意到一堆錯誤。他們都登錄到文件.xsession-errors.old中。我添加了

if [[ $(tty) = /dev/tty4 ]]; then
   mv ~/.xsession-errors ~/.xsession-errors.old
   exec startx &> ~/.xsession-errors
fi

這就是為什麼我有.xsession-errors和.xsession-errors.old文件並且可以閱讀他們的內容。例如，文件的基本部分如下所示：

xinit: connection to X server lost

             But you're not logging in as root (good!) so something
             else must be wrong.  Did you read the manual and the FAQ?

每次我openbox --exit在終端中輸入時都會收到這種消息。我發現了一些關於這個主題的類似主題，人們說錯誤是由於發送到 X-server 的 SIGTERM 信號而出現的，並且所有其他應用程序都無法再連接到它，所以它們崩潰了。

如何解決這個問題？如何在 X-server 終止之前關閉所有 GUI 應用程序？

更新#1

我嘗試了aecolley的解決方案，但不幸的是我什至無法啟動圖形環境——它只是掛起，/var/log/Xorg.0.log或.xsession-errors文件中沒有錯誤。我可以通過 重新啟動 X-server ctrl+alt+del，但我只是黑屏，僅此而已。

該解決方案的另一件事是它安裝了許多依賴項。為了擁有openbox-gnome-session，我必須安裝軟體包：openbox-gnome-session, gnome-settings-daemon, packagekit, libpam-systemd. 他們安裝了這些東西：

# aptitude install openbox-gnome-session gnome-settings-daemon packagekit libpam-systemd
The following NEW packages will be installed:
 gdebi-core{a} gnome-desktop3-data{a} gnome-session-bin{a} gnome-settings-daemon libelfg0{a} libglib2.0-bin{a} libglib2.0-data{a}
 libgnome-desktop-3-7{a} libibus-1.0-5{a} libimobiledevice4{a} libjson-glib-1.0-0{a} libjson-glib-1.0-common{a} libpackagekit-glib2-16{a}
 libpam-systemd libplist1{a} libupower-glib1{a} libusbmuxd2{a} libwacom-common{a} libwacom2{a} nautilus-data{a} openbox-gnome-session
 packagekit packagekit-backend-aptcc{a} python3-dbus{a} python3-packagekit{a} systemd{a} upower{a} usbmuxd{a}
The following packages are RECOMMENDED but will NOT be installed:
 nautilus packagekit-tools
0 packages upgraded, 28 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B/12.7 MB of archives. After unpacking 52.6 MB will be used.
Do you want to continue? [Y/n/?]

我安裝了它並添加了：

exec ck-launch-session dbus-launch --sh-syntax --exit-with-session openbox-gnome-session

或者

exec openbox-gnome-session

到 .xinitrc 文件。

即使解決方案有效，我也不會對我的系統這樣做。:) 必須有另一種方法來解決這個問題。

我想我終於找到了這個問題的原因。看起來 nvidia 驅動程序和 xorg 存在問題。我試圖只從main儲存庫安裝一個新系統，並檢查了它是否Segmentation fault會出現在日誌文件中——它沒有。所以，我安裝了nvidia驅動程序，問題又回來了。

我認為其他應用程序的大多數錯誤都與此分段錯誤有關，這就是為什麼某些應用程序在 xserver 崩潰時不能簡單地保存設置/數據的原因。

我不確定這是否涉及所有版本的 nvidia 驅動程序，但我確信這是nvidia-legacy-304xx-driver. 這很糟糕，因為我必須使用 nvidia 驅動程序，而且我不知道如何解決這個問題。也許wayland會解決這個問題，所以我想我只能等待……
