Public bug reported:
Binary package hint: acpi-support
I have a HP Pavillion dv1240us. I am running Ubuntu 7.04 (devel packages). I
find that if I suspend my laptop by selecting System --> Quit --> Suspend,
events from the Synaptics mouse and from the USB ports fail to wake the system.
After tracking this down with the ACPI developers, I eventually determined
that the necessary flags weren't set in /proc/acpi/wakeup. I would very much
like to see updates to the various Ubuntu versions that caused the needed flags
to be enabled by default.
I don't know if this bug should be assigned against acpi-support, powersaved,
acpid or some other package.
On my machine, I get:
# cat /proc/acpi/wakeup
Device Sleep state Status
PCIB 5 disabled
LAN 5 disabled
PS2K 3 disabled
PSM1 3 disabled
USB0 3 disabled
USB1 3 disabled
USB2 3 disabled
USB7 3 disabled
If I run:
# echo PSM1 > /proc/acpi/wakeup
# echo USB0 > /proc/acpi/wakeup
# echo USB1 > /proc/acpi/wakeup
# echo USB2 > /proc/acpi/wakeup
# echo USB7 > /proc/acpi/wakeup
then, when I plug in a USB device, the system wakes up.
This also causes my Synaptics mousepad to wake up the machine if I touch the
mousepad or click one of the buttons.
After running these commands, "cat /proc/acpi/wakeup" gives me:
Device Sleep state Status
PCIB 5 disabled
LAN 5 disabled
PS2K 3 enabled
PSM1 3 enabled
USB0 3 enabled
USB1 3 enabled
USB2 3 enabled
USB7 3 enabled
