Hi there,
I have a strange problem in that during a resume from hibernate my text
console (or X) remains blank - that is, until I simultaneously press a
keyboard key and touch the synaptic pad.
It is not sufficient to press just one or the other, it needs to be done
simultaneously and it resumes fine after doing this. I might be wrong
but to me actually looks like the first resume script
(/usr/lib/pm-utils/sleep.d/99info) is only invoked after this
"recovery", since I notice a "Resuming" message without a command-line
prompt in the first few seconds after recovery, so it has just started
or is still executing the resume scripts.
After the grub menu, the laptop will actually display vesafb output
(vga=791) until just after 100% loading of the hibernation image, then
the display will go blank. The laptop is a Lenovo W500 with 'hybrid'
graphics, and the Intel Mobile 4 integrated adapter is set to active.
This happens in 2.6.28, 2.6.29 and up to 2.6.30-rc6. I have had a slight
few occurrences where this did not happen (not recently), but I could
never find an explanation for the difference.
I eventually gave up on bisecting this, but it definitely still happened
in bisects just after ext4dev was renamed to ext4 somewhere after 2.6.27.
Any ideas on what I can do next? I have even tried enabling extra ACPI
debugging, but I simply do not see any debugging messages happen during
that key/synaptic combination.
Would the fact that it happens in a text console session perhaps imply
that it is ACPI or vesafb related?
Thanks in advance!
Niel

I have tried quite hard to overcome this issue. All of the following
hibernation tests I tried involved booting into a text console, without
ever starting X. With each test I still had a blank screen upon resume,
and each time it was fully recoverable by pressing any keyboard
key/synaptic pad touch combo.
1. Disabling a CPU core - NO CHANGE.
Based on a "multi-processor concurrency" fix mentioned on the web
(Ubuntu bug #272307).
2. Upgrade BIOS to latest level - NO CHANGE.
BIOS 6FET70WW, released 04/17/2009.
3. Switching to ATI Mobility Radeon HD 3650 graphics card. NO CHANGE.
My Lenovo W500 has "switchable graphics" BIOS option, and I tried this
test with both the integrated or the above-mentioned card without
difference.
_This result seems quite interesting to me, as if it could be some type
of bus related freeze where the keyboard/synaptic combo plays a role._
4. Disabling BIOS Options - NO CHANGE.
Enabling/disabling security chip features + TXT features.
Disabling fingerprint reader.
Disabling memory security feature.
5. Kernel options - NO CHANGE.
ACPI debugging - I enabled CONFIG_ACPI_DEBUG, but did not see any
messages generated when I pressed a keyboard key + synaptic mousepad
combo that recovers the console.
FIRMWARE_EDID - still testing this.
Any suggestions on anything else I could try would be most welcome...!
Thanks,
Niel

Hi Zhang,
It is not a recent regression, all of the kernels I tried back to 2.6.28 shows
the same problem. The test results I posted last night was with 2.6.30-rc6. I
suspect it did not happen in 2.6.27, but I might be wrong since I could not
bisect that far back (I am using EXT4 and have too many issues to bisect that
far back).

When I resume from suspend to RAM there is no problem.
When I resume from hibernate, my laptop actually remains unusable until I do the
combination of things I mentioned. I cannot log in from remote or even ping the
laptop, except if I first press the mentioned key combo. Before this, the
display is either entirely blank or sometimes there is a white cursor in the top
left corner.
The blank screen happens in runlevel 3 without X or "i915" loaded - I'm not sure
but I suppose you want the "xrandr" output for another reason. It is interesting
that it happens regardless of whether I am using Intel integrated graphics or
Mobility Radeon HD 3650 (my laptop has both and I can enable one at a time). I
boot the system with vga=791 and it is using vesafb for console.
I attached the output you asked for below after hibernating an Xorg session, but
this is from just after pressing the combo as I could not log in over the
network with the laptop in the blank state.
Thanks,
Niel
