Bug Description

Selecting suspend puts the system into suspend mode, but the screen isn't powered down.

Expected: When suspend is selected from menu or by closing lid, machine should power down.

Result: Machine powers down and goes into suspend mode without powering screen down. - Screen goes blank, but stays powered on.

thinkpad x31
Lucid Lynx

Note: Suspend seemed to work okay in Karmic Koala and this is a system upgraded from Karmic Koala to Lucid Lynx

Hi brad,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . However, note you can only test Suspend, not Hibernate, when using a LiveCD. If the issue remains, run the following command from a Terminal (Applications->Accessories->Terminal) it will automatically gather and attach updated debug information to this report.

apport-collect -p linux 494894

Also, please be sure to take a look at https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume . If you can provide any additional information outlined there it would be much appreciated.

Additionally, if you could try to reproduce this with the upstream mainline kernel 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. Thanks in advance.
