Public bug reported:
Binary package hint: acpi-support
I'm running Kubuntu feisty herd 5 on an HP TC4200 Tablet PC (using Intel
i810 driver, ide disks). Hibernate and suspend/resume worked very well
with edgy, but with feisty I'm having two problems:
1) When resuming after a suspend, the display doesn't come back up
(which usually points to a problem with VBE-Post). But, the acpi-
support scripts seem to be exactly the same as on edgy (since the
package didn't change from version 0.90 to 0.91) and the /etc/default
/acpi-support file in my feisty install is exactly the same as on edgy.
I'm not sure where the problem lies. Very occasionally the display will
come up but then the system hangs whenever I try to do something that
would access the disks. A hard reset is the only thing that will fix
it.
2) Suspend and hibernate take a long time to "kick in". I've confirmed
that this happens due to the 55-down-interfaces.sh in
/etc/acpi/suspend.d. If this script is removed, then the
suspend/hibernate takes place very quickly.
