Bug Description

1) Description: Ubuntu 10.10
Release: 10.10

2) I have not found what is responsible for activating the screen again after reopening the lid, but I would guess it is something in the kernel / drivers

3) After closing the lid and opening it again I expect that the screen content shows again

4) After closing the lid and opening it again, the screen remains black

I am also having the same problem on my Thinkpad X40. I didn't have this issue in the past Ubuntu Releases (not sure if it also occurs in 10.04 since X can't run on my X40 so I used it exclusively on "Failsafe x" mode.

This problem also happens in "Failsafe x" mode of 10.10.

Prunus dulcis, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag:
needs-upstream-testing

This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text:
needs-upstream-testing

If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
