For some special purpose, I modified /etc/X11/xinit/Xclients to start firefox instead of start Desktop Environment.
# Argh! Nothing good is installed. Fall back to twm
{
# gosh, neither fvwm95 nor fvwm2 is available;
# fall back to failsafe settings
[ -x /usr/bin/xsetroot ] && /usr/bin/xsetroot -solid '#222E45'
# if [ -x /usr/bin/xclock ] ; then
# /usr/bin/xclock -geometry 100x100-5+5 &
# elif [ -x /usr/bin/xclock ] ; then
# /usr/bin/xclock -geometry 100x100-5+5 &
# fi
# if [ -x /usr/bin/xterm ] ; then
# /usr/bin/xterm -geometry 80x50-50+150 &
# fi
if [ -x /usr/bin/firefox ]; then
/usr/bin/firefox -chrome http://127.0.0.1/ -width 1280 -height 768
fi
# if [ -x /usr/bin/twm ] ; then
# exec /usr/bin/twm
# fi
This used to work fine until today I tested it on another computer. Firefox reports that there's another running instance of firefox which stops responding. Thus, firefox could not autostart as I expected.
I connected the computer with SSH and I found there are 2 firefox processes:
[root@my113 xinit]# ps -ef | grep firefox

root 5717 5345 0 17:51 pts/2 00:00:00 grep firefox
I guess, for some reason, "Xclients" is executed twice. But I really knows very little about XWindows, so if anyone here could give me some clues, I will appreciate!
