[linux] Matchbox (1): startup script

Script execution order

Start the X server

/etc/rc5.d/S01xserver-nodm –> ../init.d/xserver-nodm –>
Corresponding process:
/bin/sh /etc/rc5.d/S01xserver-nodm start background

xinit /etc/X11/Xsession–>
对应进程：
xinit /etc/X11/Xsession – /usr/bin/Xorg -br -pn -nolisten tcp +iglx
/usr/bin/Xorg :0 -br -pn -nolisten tcp +iglx

Start the desktop management program Matchbox

/etc/X11/Xsession.d/90xXWindowManager.sh–>
/usr/bin/x-session-manager—>
/etc/matchbox/session
最后启动四个程序
matchbox-window-manager -theme Sato -use_desktop_mode decorated -use_cursor yes
matchbox-desktop
matchbox-panel –titlebar –start-applets showdesktop,windowselector –end-applets clock,battery,keyboard,systray,startup-notify,notify
matchbox-keyboard -d
