Kubunutu freezes while resuming from Hibernation

[quadmo]

Hi everyone,

hope someone has a hint for me. I've been working on this for two days now...

Hibernate seems to work fine. Resume works up to a certain point and then simply stops. I see the kubuntu boot screen and a message saying wait while resuming... but nothing happens.

in the syslog the last entry I get is:
acpid: client connected from 2536[0:0]

Do you know what this means? Especially the 0 in the brackets?
I have seen, that on normal startup i get the same message except that there are numbers in the brackets and no zeros.

i appreciate any help
thx, quadmo

Kubuntu 9.04 (64bit)
IntelQuad Core
ASRock G31M Mainboard

Re: Kubunutu freezes while resuming from Hibernation

two questions...
1. do you have a propertiary video card driver installed , if so whatvendor and version.

2. have you varified that you machine's acpi is enabled in your bios?

in the syslog the last entry I get is:
acpid: client connected from 2536[0:0]

Do you know what this means? Especially the 0 in the brackets?

it means that the acpi deamon was connected to by a client with a pid(process id) of 2536 on [0:0]

that 0:0, refers to the X session that made the call since you are at your machine and on the systems default monitor your on 0:0, the first # is for the v.card , the second # is for the monitor or head. (i could be slightly incorrrect about that,anyone?)

as a side note my laptop will not recover from any sleep mode, because my video card driver does not like it. it works correctly with out the video driver installed. if you do have a properitry video card driver installed then you may want to remove it and try to hybernate to remove that as a possible source of the problem.

No help, but a couple of comments.
(1) You can find out more than anyone wants to know about ACPI (Advanced Configuration and Power Interface) by looking at the Wikipedia article on the subject, and the references therein so I'm not going to demonstrate my ignorance by attempting to explain what it does.
HOWEVER
(2) Your problem MAY not be related to ACPID at all. Take a look at the last few messages in the /var/log/dmesg file. They may provide a clue as to what's going on at the time of the failure. /var/log/dmesg is the file that holds messages from the kernel.

(3) In general, look at the dates on all the files in /var/log and check the ones whose most recent entries occur around the time of the failure. Admittedly, it's usually either dmesg or syslog.

crazy ****, its working!! Thank you for your immediate support! This brought me to the right settings...

What i did was to check the video card drivers.
I haven't had any proprietary drivers installed, but while checking this, Kubuntu recommended a proprietary NVIDIA driver (under System -> Hardware Drivers).

I installed it and hibernation worked immediately, awesome!

LOL, complete opposite of what happens on mine, if i use the nvidia driver for my card i have that problem. the card is an old geforcego440 using the legacy driver.

Good to hear that is working!
