Hi Anthony,

Thanks for including the attached files. Could you also include your /var/log/Xorg.0.log (or Xorg.0.log.old) from after reproducing the issue?

Please attach the output of `lspci -vvnn` too.

Sorry it took so long to get back, can only really look at this issue at the weekends.

I have changed from the open source ATI driver to the propriety one, and the symptoms are slightly different, but the problem remains.

This time, when I press Ctrl-Alt-F2, I can log in and restart safely. Also, the cursor is still visible on F7.

Anthony Batchelor, 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 xorg-server REPLACE-WITH-BUG-NUMBER

Thank you for your understanding.
