another hack success:

adding chvt 1 before suspend

and

chvt 7 after vbetool post

did the trick and preserves X

it's a hack, but it works

so here's my script:


---

#!/bin/bash
#. /usr/share/acpi-support/key-constants
##acpi_fakekey $KEY_SLEEP=20
#/etc/acpi/sleep.sh sleep

CPU0GOV=3D`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor`
CPU1GOV=3D`cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor`

if [ x$CPU0GOV =3D=3D xpowersave -o x$CPU0GOV =3D=3D xperformance ] ; then
   echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
fi

if [ x$CPU1GOV =3D=3D xpowersave -o x$CPU1GOV =3D=3D xperformance ] ; then
   echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
fi

chvt 1

echo -n mem > /sys/power/state

#vbetool dpms on
vbetool post
sleep 1

chvt 7
