[gentoo-user] Resuming after hibernate

[gentoo-user] Resuming after hibernate

[Sergey Kobzar]

Resuming does not work for my laptop after it hibernates - OS boots
normally and does not use resume image created by s2disk.


Linux 2.6.30-gentoo-r8 i686
Kernel command line: root=/dev/sda6 vga=0x317 video=vesafb:mtrr:3,ywrap resume=swap:/dev/sda5

# cat /usr/src/linux/.config | grep CONFIG_PM_STD_PARTITION
CONFIG_PM_STD_PARTITION="/dev/sda5"

sys-power/hibernate-script-2.0-r1
sys-power/suspend-0.8-r1


To suspend laptop I uses 'hibernate' command which uses s2disk tool

# cat /etc/suspend.conf
snapshot device = /dev/snapshot
resume device = /dev/sda5


When the system boots up:

* Activating (possible) swap ...
swapon: /dev/sda5: Invalid argument

....

* Invalidating stale software suspend images ...
/sda5


It looks like that kernel knows nothing about suspend image and does
not use it.

Any ideas?

Thanks.

  Why do you need anything in the kernel commandlindline?  Everything is
done either in the kernel config or in hibernate.conf.  "make menuconfig"
on my machine goes like so...

=========================================
Power management and ACPI options  --->

  [*] Power Management support
  [ ]   Power Management Debug Support
  [ ] Suspend to RAM and standby
  [*] Hibernation (aka 'suspend to disk')
  (/dev/sda6) Default resume partition
=========================================

  Your system should have /dev/sda5.  I ran "emerge hibernate-script"
and then executed "rc-update add hibernate-cleanup boot" so that when
the machine comes up from "reboot" or "halt -p", it doesn't try to load
the swap file as memory state.

  Here are the uncommented lines in my hibernate.conf.  The last 4 lines
are specific to my machine, and may not apply to yours.  It works great
for me.

TryMethod disk.conf
Distribution gentoo
DownInterfaces auto
PowerdownMethod shutdown
UseSysfsPowerState disk
UpInterfaces auto
OnResume 99 chvt 1
OnResume 98 setfont lat1-10
OnResume 97 /etc/init.d/sshd restart
OnResume 96 alsactl restore

I have same settings in my kernel too:
CONFIG_ARCH_HIBERNATION_POSSIBLE=y
CONFIG_HIBERNATION=y
CONFIG_PM_STD_PARTITION="/dev/sda5"

Just added the 'resume=swap:/dev/sda5' to grub.con to be 100% sure
it's not a kernel bug.

I did this too.
Also I emerged sys-power/suspend because without this tool
hibernate-ram does not work for me (display is blank after resuming).

/etc/hibernate/common.conf:
Verbosity 0
LogFile /var/log/hibernate.log
LogVerbosity 1
Distribution gentoo
SaveClock restore-only
UnloadBlacklistedModules yes
LoadModules auto
SwitchToTextMode yes

/etc/hibernate/hibernate.conf:
TryMethod tuxonice.conf
TryMethod disk.conf
TryMethod ram.conf

cat /etc/hibernate/disk.conf
TryMethod ususpend-disk.conf
TryMethod sysfs-disk.conf

/etc/hibernate/ususpend-disk.conf:
USuspendMethod disk
Include common.conf


Btw, am I right pressing 'power' button to resume from suspend to
disk?

Btw, s2disk is user-level tool. According to http://wiki.archlinux.org/index.php/Suspend_to_Disk
initrd image is required to resume from image created by s2disk tool,
but I don't use initrd.

Maybe this is a reason? Probably I need switch to native swsusp?..

how come?  To kill any stale ssh connections?  I find that they clean
themselves up fairly well.  In fact, if I hibernate and resume in enough
time, an existing ssh won't be disconnected (and still works).

  I find that for some reason sshd doesn't restart on resume.  I tested
it 2 minutes ago...
  - ssh from my laptop... OK
  - disconnect
  - comment out the OnResume statement
  - hibernate the desktop
  - resume the desktop
  - ssh from my laptop... Connection refused
  - manually enter "/etc/init.d/sshd restart" (as root)
  - ssh from my laptop... OK
  - and remember to uncomment the OnResume

  For that matter, the console font setting is forgotten as well.  I
have VGA=6 in lilo.conf (probably works in GRUB as well), which defaults
to an unreadable 80 columns x 60 rows display.  This is done by
selecting the 640 pixels by 480 scanlines mode, and the 8-pixel high
font.  480 / 8 = 60 rows.  Selecting 10-pixel high font gets
480 / 10 = 48 rows (YES!).  And thanks to the extra pixels, the font is
*MUCH* nicer than standard 80 x 50 (using 8-pixel high font with 400
scanlines).  No 2 ways about it, 10-pixel high font beats out 8-pixel
high font on a text console every time.

weird... is networkmanager getting in the way?  I also have
rc_depend_strict="NO" in /etc/rc.conf

Did I read that right?  You have a setting in lilo.conf that makes your
font unreadable?  Then why do you have that in lilo.conf?

what about the normal `hibernate` script?  I'm not exactly sure what
s2disk is, and I've never used it...

  You didn't read the entire post.  The *DEFAULT* result of 'VGA=6' in
/etc/lilo.conf gives an 8x8 font which results in an 80x60 display.
*IN ADDITION* I set 'CONSOLEFONT="lat1-10"' in /etc/conf.d/consolefont,
which gives me an 80x48 row display, using 8x10 font, which is *MUCH*
nicer than 8x8 font.

  The reason I do 'VGA=6' in /etc/lilo.conf is because that is a
quick-n-dirty way to kick the display into a 480 scanline mode, instead
of the default 400 scanline mode.  It's a lot safer and easier than
screwing around with SVGATextmode (is it still around?).

  Anyhow, upon resuming from hibernation, Gentoo remembers the 480
scanline mode, but does not remember the non-default font, which is why
I have to reset the font via the OnResume option.
