Several months ago, I posted a thread over in the Slackware forum regarding resume problems I'd been having with an HP DV7-1130us laptop. With some web scouring, I've made **some** progress, but, still have at least 1 issue.
The original problem was a dead keyboard and synaptics touchpad upon a resume from suspend to ram via "echo -n mem > /sys/power/state" or with pm-utils. The problems exists on Slackware 12.2 (2.6.27.7-smp) and on all versions of Zenwalk 6 (2.6.28.7).
I added "i8042.reset" to the end of the kernel line in grub. FYI- "i8042.nomux" results in the above mentioned dead keyboard and touchpad.
I also built the following script for suspend and have it in /etc/acpi/actions
Code:
#!/bin/sh
/sbin/rmmod ohci_hcd
/sbin/rmmod ehci_hcd
/usr/bin/chvt 1
sync
echo -n mem > /sys/power/state
/sbin/modprobe ehci_hcd
/sbin/modprobe ohci_hcd
/usr/bin/chvt 7
exit 0
Now, the laptop suspends and resumes fine. I have a live keyboard and touchpad. That's the "**some** success".
The problem now is, if I shutdown, logout, or reboot from X, after resuming from a suspend to ram, I get a blank screen with the backlight on and the machine hangs. Ctrl-Alt-Fn or Alt-Fn have no effect and a hard power off/on is required.
I'd love some advice.....
Thanks,
Mark
