Suspend/hibernate prob. HP 6420

Hello there folks!
I'm pretty new to Linux, and I love it!

But unfortunately I'm having a problem with suspend/hibernate, both in LinuxMint and Zenwalk... Tried a lot of things, but haven't got to far. Soo, I'm just wondering if you guys have any suggestions?
Maybe someone has the same laptop or something...?

If you are using the closed driver fglrx for your ati card you might have do unload fglrx before suspending

Code:

sudo rmmod fglrx

This worked for me when having the same problem.
you can also check what states your computer supports

Code:

cat /sys/power/state

And if you have support for mem or and disk it should work
You can also try suspending manually

Code:

sudo echo mem > /sys/power/state

to suspend to memory or

Code:

sudo echo disk > /sys/power/state

to hibernate to disk

I hope this will work for you, and as i said i think it is the fglrx driver. I tried the latest driver for ati and didn't have that problem.

Hi, again! Thank's, but it's still not working. The graphics card is a Nvidia tough. When I typed in

Code:

cat /sys/power/state

it said mem disk. Tried to suspend manually, but then I just got "Permission denied".

I hibernate my notebooks (various types, various graphic-chips) with a little script (I know there are hibernate scripts too, but I do not need these scripts):

Code:

#!/bin/sh
# switch to virtual terminal 1 to avoid graphics
# corruption in X
chvt 1
/sbin/hwclock --systohc

# write all unwritten data (just in case)
sync

# suspend
echo -n disk > /sys/power/state

/sbin/hwclock --hctosys

# switch back to tty7
chvt 7

Make it executable and run it as root or as user with "sudo" and the correct line in /etc/sudoers.

If you have a NVIDIA graphic card/chip, please add to your device section the line:

Code:

Option "nvAGP" "1"

So the notebook will come back to tty7.

In your bootloader configuration have to be the append "resume=/dev/your_swap_partition" or if you use suspend2 "resume=swap:/dev/your_swap_partition".

Fluxx.
