Totally of topic, but there seems to some interest in suspending. This is my suspend script (works fine on thinkpad G40):
#!/bin/sh #set -x # Initial settings umask 0077 PATH="/sbin:/bin:/usr/sbin:/usr/bin" # Suspend #echo "Going to sleep at `date`" echo "* chvt 1" /usr/bin/chvt 1 /etc/init.d/mysql stop #echo "* save vbestate" #/usr/sbin/vbetool vbestate save > /etc/acpi/vbestate echo "* writing to /sys" echo -n "mem" > /sys/power/state echo "" # Resume echo "Back from sleep at `date`" echo "* restore vbestate" /usr/sbin/vbetool post #/usr/sbin/vbetool vbestate restore < /etc/acpi/vbestate #/bin/cat /etc/acpi/vbestate | /usr/sbin/vbetool vbestate restore echo "* restore clock" /sbin/hwclock --hctosys echo "* chvt 7" /usr/bin/chvt 7 echo "* done" echo "" /etc/init.d/mysql start echo "*Reconfiguring network" whereami Stef
