Reporting a confirmed X bug to Launchpad

Initial filing of the report

First, one will want to familiarize themselves with how to report bugs effectively as per here.

Once this is reviewed, please file a new bug report with Ubuntu via a terminal:

ubuntu-bug xorg

Please ensure you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

Including enough information for a developer to work on it

One will want to answer the following questions:

  • Does the report include debugging information from the relevant article relating to the reported issue?
  • Is this a regression?
  • Does this happen in the latest version of Ubuntu?
  • Does this happen in the latest version available from upstream?
