I'm trying to build an info display (or Digital Signage Monitor) with Raspberry Pi running Raspbian (so a Debian distro). I need to start two X servers, where one is showing the content (through Iceweasel) and the other is an optional WLAN configuration GUI. The latter should only be shown after pressing the corresponding Shift+Alt+Fn combination. Otherwise Iceweasel should ALWAYS be displayed.

I have two simple scripts starting Iceweasel and the WLAN config. On boot, I log user Pi into terminals tty1 and tty2 (in /etc/inittab). After login (in /home/pi/.bash_profile) I start two X servers, depending on the terminal I am on. Here's the code in .bash_profile:

if [ $(tty) == /dev/tty1 ]; then
startx /home/pi/scripts/autostart -- :0
fi

if [ $(tty) == /dev/tty2 ]; then
startx /home/pi/scripts/wlanconfig -- :1
fi

I want to have two virtual desktops without a window manager showing only Iceweasel or WLAN config. This works so far, the only problem is that sometimes Iceweasel starts is displayed and sometimes the config GUI. The :0 or :1 argument obviously doesn't influence the start priority. I need Iceweasel to always be displayed.

I am an experienced Windows user, but have my problems understanding some of the Linux concepts.

Alright, I found an answer to my problem. A bit of a workaround, but it works for me:

I added a parameter to startx to determine the virtual terminal:

startx /home/pi/scripts/autostart -- :0 vt8

and vt7 for the other script.

Then I switched the visible terminal with the command chvt 8 as the last command in 'wlanconfig', so that I jump to the right screen, even if the wrong one was booted.
