Suspend/Hibernate under Debian
Hi,
I'm trying to get Suspend/Hibernate works with my Debian Laptop. Please
recommend a good article/blog/site for me to follow.
I've done some extensive search, but it's still not working. I first
tried suspend to ram (because I know suspend to disk need extra work),
but the symptom is similar to
Laptop won't resume from suspend to ram
http://thread.gmane.org/gmane.linux.debian.user/370058/focus=370097
My case: the machine won't resume from a suspend to ram. It's not
just a problem with a blank screen upon resuming; the machine
actually gets completely frozen. I can hear the hard disk
spinning though. and I can see the the wireless LED come on when
resuming, then nothing else. Ctrl-Alt-F1, Ctrl-Alt-Del, and even Caplock
keys won't respond.
Following suggestions from it, I did
PM_DEBUG=1 pm-suspend (as root)
and check the log file /var/log/pm-suspend.log, and it seems to have
suspended fine.
The last several meaningful lines are:
+ [ Thu Jan 28 17:48:01 EST 2010: performing suspend = -n ]
+ printf %s\n Thu Jan 28 17:48:01 EST 2010: performing suspend
Thu Jan 28 17:48:01 EST 2010: performing suspend
+ sync
+ do_suspend
+ echo -n mem
And after that all garbage.
The Suspend/resume works out of box in Unbunto, on my Acer Aspire
(AS5536). I wasn't able to test Hibernation under Unbunto because it is
not available.
Please help.
Thanks
PS. I'll quote one page that I found that precisely express my
frustration:
"I’ve been working with Linux for ten years now. I have seen issues come
and I have seen them go. But there’s one issue that has always surprised
me because it just seems to never go away: Suspend/Hibernate. I am always
so surprised about this because it just seems like a fundamental issue on
laptops - and let’s face it, laptops are standard issue for many people -
you close the lid, the laptop suspends.
... it seems to me that hibernate and suspend IS a need that should be
given a high priority.
And it seems it is starting to gain some traction. There’s a new site
called the Ubuntu Brainstorm that allows users to add ideas for Ubuntu
and vote up or down ideas that are already posted (as well as comment on
ideas)..."
