This bug start showing when I upgraded from Xubuntu 8.04 "Hardy Heron" to 10.04 "Lucid Lynx". X start correctly when a monitor is plugged but not when no monitor is plug. I used X without a monitor by vnc for several month with Xubuntu 8.04 "Hardy Heron".

Guillaume Coté, 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 xorg-server REPLACE-WITH-BUG-NUMBER

Please note, given you already have done this in a prior release, performing this on a release prior to Trusty would not be helpful.

Thank you for your understanding.
