bypassing login

I am writing an application for a computer that will not have a keyboard
and will gain all user input via a touchscreen. I would like to bypass the
login window when photon starts and just have a default user be logged in
at that time. Is this possible or am I trying the impossible? Thanks in
advance.

Here’s how we do it:

  1. Set BIOS so the PC doesn’t require a keyboard

  2. Don’t invoke Photon with “-lphlogin”


    Here’s part of the script we call from /etc/config/sysinit:


    export PHOTON_PATH=/usr/photon
    export PATH=/bin:/usr/bin:/usr/photon/bin:.

/usr/photon/bin/phlib_s11
/usr/photon/bin/Aplib_s11
/usr/photon/bin/phlib_render_11
Photon &

Input kbd -R fd -d/dev/kbd dyna -b2400 fd -d/dev/ser1 &
sleep 1
phfontphf &
vesabios.ms -i0x12 &
sleep 1
Pg.vga4 -g640x480x4 -A0xA0000,0x10000 -WB80 &


This uses standard 4-bit VGA and a Dynapro touchscreen controller.

Would it help you to login the default user from sysinit and start ph from
the default user’s .profile?

I have used export LOGNAME=xxx to allow me to bypass the phlogin but I
would really like to log a specific user in. Any ideas on this one? I
looked at the manual for phlogin but could not figure out how to log on a
particular user. Any help would be greatly appreciated. Thanks.
