Nicholas J. Fiorello Jr., 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 test for this with the latest development release of Ubuntu? ISO images are available from .

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 (not the daily folder) following ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. 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. For example:

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:

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

As well, please remove the tag:

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Changed in linux (Ubuntu):
importance: Undecided → Medium
status: Confirmed → Incomplete

Given that:

1) The config file : /etc/default/tmpfs is no longer installed and therefore doesn't contain a comment that says "Adjust the default size of /dev/shm by uncommenting the line below" (or whatever it said exactly)

2) /dev/shm is now mounted as /run/shm who's size is controlled by some other form of black magic

3) The reason I needed the size change was to tweak the now obsolete vmware server 2.x

I'd say this issue can be folded, spindled, and mutilated.

Nicholas J. Fiorello Jr., given the original bug reported is no longer addressable due to the changed backend circumstances, let us close this. However, if you are having an issue with your current virtualization setup, please file a new report via a terminal:
ubuntu-bug linux

Thank you for your understanding.
