["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Richard Genoud, 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.

Title:
  blank screen after fast-user switch

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: gnome-screensaver

  This may be a duplicate of https://bugs.launchpad.net/bugs/112518 
  But it's happening with ubuntu 10.04.
  Here's the description.

  Log with user A via gdm.
  Set the screensaver to 1min (blank screen or whatever).
  fast-switch to user B.
  wait more than 1 min.
  Fast-switch to user A.

  => the screen is blank, no message from gnome-screensaver to unlock. There's only the mouse pointer.
  I can still switch to console with ALT-Fx, but the screen is blank (I have to type blinded).
  If I restart gdm, the screen is back.

  When this happened, I could see via ssh that the gnome-screensaver
  process of user A launched gnome-screensaver-dialog process with
  argument --enable-switch and --status-message=

  I uninstalled gnome-screensaver, made sure its processes were not running and try this:
  Log with user A via gdm.
  Set the power-manager to switch off the screen after 1 min.
  fast-switch to user B.
  wait more than 1 min.
  Fast-switch to user A.
  And the screen was OK.

  my video card is ATI Technologies Inc RV710 [Radeon HD 4350]
  and I'm using KMS (default lucid configuration).
  I'm not using compiz or anything related to visual effects.

  package: gnome-screensaver 2.30.0-0ubuntu1
