[Splashy-devel] Bug#421441: splashy: splashy->gdm hangs system randomly

[Geoffrey L. Brimhall]

Package: splashy
Version: 0.3.2
Severity: important

There is a race condition between when splashy ends and gdm starts that
happens on my system about 1 in 3 boots, when it happens the splashy
screen is just "hangs" and console switching to X doesn't work. Think it
may be related to my system being SMP (dual core ).

This bug is really identical to #350179 - so either close this bug or
re-open that one !

By updating the gdm and splashy scripts I got rid of the race condition,
here's the fix ( note the fix really requires updating all display
manager scripts to be aware if a boot gui is being used, if so shut it
down ):

REMOVE from splashy script in the "start" sequence:

        else
            log_daemon_msg "Stopping $DESC" $NAME
            /sbin/splashy_update exit
            log_end_msg $?
            # wait until splashy exits before changing tty's
            while `pidof splashy > /dev/null`; do
                sleep 0.2
            done
            # do some magic with the TTYs
            if test -z "$CHVT_TTY"; then
		CHVT_TTY=1
            fi
            # detect X, if not, go to CHVT_TTY
            X11_RUNNING=1
            pidof X > /dev/null && X11_RUNNING=1
            if [ $X11_RUNNING -eq 1 ]; then
                splashy_chvt 7
            else
                splashy_chvt $CHVT_TTY
            fi

ADD to gdm script the above functionality, before the "start_daemon"
command:

      # Disable splashy if running
      if `pidof splashy > /dev/null`; then
            log_daemon_msg "Stopping $DESC" $NAME
            /sbin/splashy_update exit
            /sbin/splashy_chvt 7
            log_end_msg $?
      fi
