Video garbled/maxtearing after switching users

I noticed that I have two kernels to boot with. When I tried 2.6.35.22 instead of 2.6.35.24 the Indicator Applet Session 0.4.6 switches users fine. Switching users with User Switcher Applet 3.30.5 causes garbled graphics.

Also when a click on System/About Ubuntu, it says: "You are using Ubuntu 11.04
                - the Natty Narwhal - released in April 2011 and supported until October 2012."

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in the kernel.

Mark Mueller, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 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. Please let us know your results.

Thanks in advance.

Christopher,

I haven't had this problem for quite a while. It's a computer that I don't
use very often now. I can check what version of Ubuntu is running on it
some time.

Best Regards,

Mark.
