Re: Resume from suspend (S3) - is there a 'generic' troubleshooting guide?

Try this for a start

Let me know if it works:

suspend /resume

Re: Resume from suspend (S3) - is there a 'generic' troubleshooting guide?

Well I'll be... THAT "just worked"

, although there are some things I'd like to point out, which I didn't do:

ACPI_SLEEP_MODE=standby

comment at this line says:

Code:

# Change the following to "standby" to use ACPI S1 sleep, rather than S3.
# This will save less power, but may work on more machines

Since S1 is pretty much "everything - HDD & video" ON, it defeats the purpose of suspend

As for the "NvAGP" option in xorg.conf, I already had that

My guess is that agpgart module causes trouble - I'll try to revert the settings in /etc/default/acpi-support one-by-one and see what happens.. Anyway, thanks!

UPDATE!
The module is innocent - it's most likely the video driver's (nvidia 9639) fault for not providing the VBE functionality etc... Maybe even DPMS might work, this is what my (working) file looks like now>

Code:

# Comment the next line to disable ACPI suspend to RAM
ACPI_SLEEP=true

# Comment the next line to disable suspend to disk
ACPI_HIBERNATE=true

# Change the following to "standby" to use ACPI S1 sleep, rather than S3.
# This will save less power, but may work on more machines
ACPI_SLEEP_MODE=mem

# Add modules to this list to have them removed before suspend and reloaded
# on resume. An example would be MODULES="em8300 yenta_socket"
#
# Note that network cards and USB controllers will automatically be unloaded 
# unless they're listed in MODULES_WHITELIST
MODULES=""

# Add modules to this list to leave them in the kernel over suspend/resume
MODULES_WHITELIST=""

# Should we save and restore state using the VESA BIOS Extensions?
# fails!
SAVE_VBE_STATE=false

# The file that we use to save the vbestate
VBESTATE=/var/lib/acpi-support/vbestate

# Should we attempt to warm-boot the video hardware on resume?
# fails!
POST_VIDEO=false

# Save and restore video state?
# SAVE_VIDEO_PCI_STATE=true

# Should we switch the screen off with DPMS on suspend?
USE_DPMS=false

# Use Radeontool to switch the screen off? Seems to be needed on some machines
# RADEON_LIGHT=true

# Uncomment the next line to switch away from X and back again after resume.
# This is needed for some hardware, but should be unnecessary on most.
# DOUBLE_CONSOLE_SWITCH=true

# Set the following to "platform" if you want to use ACPI to shut down
# your machine on hibernation
HIBERNATE_MODE=shutdown

# Comment this out to disable screen locking on resume
LOCK_SCREEN=true

# Uncomment this line to have DMA disabled before suspend and reenabled
# afterwards
# DISABLE_DMA=true

# Uncomment this line to attempt to reset the drive on resume. This seems
# to be needed for some Sonys
# RESET_DRIVE=true

# Add services to this list to stop them before suspend and restart them in 
# the resume process.
STOP_SERVICES=""

# Restart Infra Red services on resume - off by default as it crashes some
# machines
RESTART_IRDA=false

# Switch to laptop-mode on battery power - off by default as it causes odd
# hangs on some machines
ENABLE_LAPTOP_MODE=false

# Spindown time on battery
SPINDOWN_TIME=12

I'll keep tinkering with this and modify this post if anything changes (no much use to post new replies IMO

).
