Bug Description

I submitted another report an hour or two ago. I managed to boot into safemode, and while I have the same problem, I am at least now able to submit a report. The brightness bar, appearing in the upper right screen, appears and the screen flickers. My programs will not run, my computer freezes.

Running Ubuntu 12.04 LTS 32-bit on a Samsung laptop, This problem only begun today after an update. I ran a debug process in the terminal, hopefully this provides more info. I have marked this as a possible security threat, although i apologize if that is wrong.

There is no output from minimum recommended output. However, the ubuntu-bug linux report should be attached. Please email me ASAP at <email address hidden>

Alexander Bumgardner, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please capture the oops following https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Capturing_OOPs ?

As well, 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:

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:

If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested.

Please let us know your results. Thank you for your understanding.

I disagree that my bug is a duplicate of 1028151. I tested the kernels, and the new 3.2.30 kernel with the supposed "fix". My laptop is still messed up. The only thing that worked was a test kernel that was a 3.6 one...
