Bug Description

This started happening with Maverick - I had no problem with Lucid.

I'm using an Lenovo ThinkPad T61 with Intel GM965 graphics chip. When I close the lid with the power connected, gnome-power-manager is configured to blank the screen, and that works well, but when I open the lid again after some time has passed (I haven't been able to reproduce this with just close the lid and open it immediately - some time has to pass) then the screen turns back on, I can see that the screen is powered on but the picture is black with nothing on - not even a mouse cursor.

At this point I can't do anything - CTRL+ALT+Fx doesn't move to a different terminal and there is no way to communicate with the computer through the terminal. I have to power cycle the computer.

I haven't had a freeze for a couple of days now, possibly since I upgrade the kernel to Maverick's 2.6.35-8 .

Oded Arbel, 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, can you try 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 run the following command in a supported release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

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

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. 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 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.
