hi Tom 
we use the same platform, but the issue doesn't occur, driver version 2.6.3 is old for us, could you please update your driver from our master tree?

Thanks

I tried it with the ubuntu 9.04 live CD and was able to reproduce the issue. Should I upload a video showing this? I suspect you're maybe testing on different hardware?

Should I wait to see the response from my last comment, as I am able to reproduce the problem with the 9.04 live CD?

I have a very similar problem which might have the same root cause.
(see bug report https://bugs.launchpad.net/bugs/352708)

Most notably, it only happens if you suspend via lid. When using pm-utils or suspending by power-button, display configuration stays intact.

Also, if you switch over to KMS, the problem goes away as well.

Tom, can you confirm if these two assumptions are correct for your problem as well?

Will you please do the following test under the console mode?
   a. kill the process using the /proc/acpi/event(use the command of "lsof /proc/acpi/event" to get the process id).
   b. cat /proc/acpi/event >user_event and don't press "CTRL + C" until the step C is finished.
   c. close/open the lid several times
  
After the test, please attach the output of user_event.
Thanks.

ping...if the problem is gone in KMS, we probably won't chase to fix it for UMS anymore.

My problem from comment #10 can be attributed to my BIOS sending a "video button" event when the lid is closed. For more details see https://bugs.launchpad.net/bugs/352708. Can't say about the original bug report though.

Hi, Tom
    Will you please confirm whether this issue is also related with the LID script as described in comment #10?
    If not, please attach the output of acpidump. The latest acpidump tool(pmtools-20071116) can be found in :
    http://www.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/*

thanks.

Unfortunately I no longer have the monitor in question. I'm in the process of moving and couldn't move it with me.

Tom, the bug shouldn't be monitor specific. If you can still reproduce this bug with another monitor, please follow up with yakui's comment# 14. If can't reproduce this bug with another monitor anymore using KMS, we will close this bug then. thanks.

Closing due to inactivity.  I think this one is fixed though.
