Jeremy Yoder, 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 http://cdimage.ubuntu.com/daily-live/current/ .
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 https://wiki.ubuntu.com/KernelMainlineBuilds ? 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: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc3 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: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing 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. ** This bug is no longer a duplicate of bug 546578 black screen after a few user switches ** Package changed: fast-user-switch-applet (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/574909 Title: Getting a black/blank screen when switching between users in lucid Status in “linux” package in Ubuntu: Incomplete Bug description: Binary package hint: fast-user-switch-applet Not sure this is the right applet, but it seems to be affecting a number of people. 1) Ubuntu 10.04 LTS (lucid) 2) Unknown (I assumed fast-user-switch-applet, but I can't find a version number for it, so maybe this isn't part of Lucid?) 3) Switching between 2 users repeatedly should work 4) It fails after 1-3 switches with a black/blank screen Steps to repeat: - Boot ubuntu and login to user A - Then Click on power menu (top right corner) and select: Switch from A - I get the login screen - I select user B and enter my password - I hit ok - I am able to login successfully to user B - Now, I Click on power menu (top right corner) and select: Switch from B - I select user A from the login screen and enter my credentials, then hit OK - I get a black screen Alternatively: - Boot ubuntu and login to user A - Then Click on power menu (top right corner) and select: Switch from A...
