[Bug 1313275] Re: relogin fails with black screen, Xorg high load


Gerben, 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 as it will automatically gather
and attach updated debug information to this report:

apport-collect -p xorg 1313275

Please ensure you have xdiagnose installed, and that you click the Yes
button for attaching additional debugging information. As well, please
note given that the information from the prior release is already
available, doing this on a release prior to the development one would
not be helpful.

Thank you for your understanding.

  relogin fails with black screen, Xorg high load

Status in xorg package in Ubuntu:

Bug description:
  Using a desktop with two users, it often hangs switching from one to
  another. The console comes unresponsive, even text-only (ctrl-alt-f2)
  does not show. System itself still runs, I can login over SSH. Process
  for Xorg shows one full cpu used.

  The system came up from hybernate, the graphical display showed
  password entry for other user, the switch towared the one user showed
  the password entry for the one user. After entering the password the
  display turns black, with ctrl-alt-f2 not responding either.

  Via ssh I can produce the following: (3-core cpu):
