[Bug 816139] [NEW] Kiosk mode fails when setting KIOSK_EXE

[Vinicius Massuchetto]

Public bug reported:

Ubuntu 11.04
LTSP Server version 5.2.8-0ubuntu1 i386

While setting KIOSK_EXE to some custom app on lts.conf I get a Xorg
error that stops on the screen:

"Invalid argument for -config. For non-root users, the file specified
with -config must be a relative path and must not contain any ".."
elements. Using default xorg.conf search path."

Running `ps -ef` on the client I get the line:
xinit /usr/share/ltsp/xinitrc /usr/share/ltsp/kioskSession <custom_script> -- :7 vt7 -config /var/run/ltsp-xorg.conf -br

On file: /opt/ltsp/i386/usr/share/ltsp/screen.d/kiosk
In this line:
su - ${KIOSKUSER} -c "XINITRC_DAEMON=${XINITRC_DAEMON} xinit $xinitrc /usr/share/ltsp/kioskSession ${KIOSK_EXE} ${KIOSK_OPTIONS} -- ${DISPLAY} vt${TTY} ${X_ARGS} -br" >/dev/null

If I remove ${X_ARGS} things work fine. However, the X_BLANKING option
seem not to work when doing this.

Please let me know about any other information that I can provide to
troubleshoot this.
