If you're using 2.6.25 or later it's also worth checking whether you can do a suspend/resume from the console directly: <boot to text mode> # modprobe i915 # echo mem > /sys/power/state <resume> If that comes back then at least the basic kernel functionality is working. If X still doesn't work though I'll want to get some more details. -- Jesse Barnes, Intel Open Source Technology Center _______________________________________________ Pm-utils mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pm-utils
