Attach your /var/log/Xorg.0.log file before hibernate and after hibernate

[Chris (christophe-lindheimer)]

Just to clarify, pm-hibernate works fine.
So not sure you wanted logs with pm-hibernate...

Issue is only with pm-suspend.

With the pm-suspend, after the full reboot I have the following lines in the Xorg.0.log.old :

[ 19.858] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/mouse1)

Hi

I have started my laptop in recovery mode.
I start a root console
make a pm-suspend

--> blank screen when I try to boot.

So not sure that the root cause comes from the Chrome driver...

[Bartosz Kosiorek (gang65)]

Check if this problem exists on Lucid Lynx

Tested on a usb stick with Lucid Lynx from X -> fails (blank screen)

I'm just installing an eCafe for a friend. Sorry I can't and don't know how to do deeper tests, but this bug also affects kernel 3.0.14 in oneiric.

The funny thing is that suspend and resume works nearly fine for EXACTLY one time after a double reboot following a change in bios' ACPI-settings.
No matter if I change from ACPI version 1.0 to 3.0 or switch APIC support or a thing called "headless mode", one time, everything nearly works, except the touchpad always not reacting after that successful resume.
Further attempts to suspend and resume result in display trouble and no reaction whatsoever any more.

I'm no expert, but it seems to me as if it learned something wrong from the first attempt.

I did sudo sh -c "sync; echo 1 > /sys/power/pm_trace; pm-suspend" and tried to reboot as soon as possible to dmesg into a file as the ubuntu wiki suggested, but the whole file was only full of "uvcvideo: failed to query .. GET_..". I don't remember the exact line.

As I said, I can't test no more because I have to give the netbook back.

Kind regards

christian
