Graphical artifacts in launcher after resume from suspend

Asked by Joel Wright

I am running Ubuntu 11.04 on a Lenovo T61 with a discreet Nvidia Quadro NVS 140M GPU.

I have noticed that whenever I resume from a suspend, the launcher area is covered with a white/black graphical artifact. I took a screenshot which shows part of the problem, but for some reason does not show the artifact in its entirety - when I resume, the ENTIRE launcher is covered by this white snow (though in the screenshot only part of it is). I was hoping to post the screenshot, but I am new here and don't know how to do that.

This artifact goes away when I mouse over the launcher. However, it is unsightly.

In the future, you can post screenshots elsewhere on the web (for example, at http://postimage.org), and link to them from https://answers.launchpad.net. However, in this case, I recommend you submit a bug report. So you can just attach the screenshot to the bug report.

First, read https://help.ubuntu.com/community/ReportingBugs carefully. Then search to see if the bug has already been reported (that's one of the things that page explains how to do). If you find this bug, you can subscribe to it, mark it as affecting you (using the green "This bug affects..." link near the top of the bug page) and, if you have information to contribute, post a comment / comments in the bug. If there are other bug reports that you think might be for the same bug but you're not sure, then you can refer to them when you compose your own bug report. To actually report a new bug, the best way to do it is to produce the problem, then run ubuntu-bug with the PID of the running unity process (that will make sense after you've read the page on Reporting Bugs).

After you've reported your bug (or found that it has already been reported), you can link the bug and this question page to each other by using the "Link existing bug" link near the top of this question page. That's a good thing to do, but your bug report should nonetheless be complete and self-contained--it should not be necessary for the Ubuntu developers to refer to this question in order to fully understand and appreciate your bug report.

Thank you for your advice Eliah. I have found that this does in fact correspond to an existing bug (# 755230 on Launchpad) so I have posted my screenshot there.

I had originally tried to use the "ubuntu-bugs" process described in the tutorial, but I got a message saying that since Natty had moved beyond Testing stage, I should check Canonical support before posting the bug - that is what led me here.

Can you help with this problem?

Provide an answer of your own, or ask Joel Wright for more information if necessary.
