I read the link you referenced. I don't think the instructions are 100%
correct. The
original instructions I received from Scott B did not have me copy ldm to the
screen.d
location. The files already existed. I'll post the original instructions
below, then
I'll post the contents of my $CHROOT/usr/lib/ltsp/screen.d/ldm under that so
you can
rebuild yours. I wonder if the extra stuff in that ldm script is whats causing
your
trouble.
############# Original Instructions #####################
First add the following to "/opt/ltsp/i386/usr/lib/ltsp/screen.d/ldm" above the
last line in the file that currently reads "exec ldm vt$ttynum :$displaynum":
XRAMPERC=${XRAMPERC:-100}
if [ ${XRAMPERC} -lt 100 ]; then
XMEM=0
while read TYPE VALUE UNITS; do
case ${TYPE} in
MemFree:|SwapFree:)
XMEM=$((${XMEM} + ${VALUE}))
;;
esac
done < /proc/meminfo
XMEM=$((${XMEM} * ${XRAMPERC} / 100))
ulimit -v ${XMEM}
fi
Save the file and then modify /opt/i386/ltsp/etc/lts.conf and add the following
to your
[Default] section:
# Set maximum percentage of RAM consumed by X
XRAMPERC=80
