Identifying if the issue is a bug or not

If you aren't sure if you have encountered a software bug in Ubuntu, then you would want to seek help in determining if the issue is a bug or not from here.

If you have confirmed the issue is a bug, please read on.

Determining which type of bug you have

Not all bugs where X seems to be the root cause are in fact an X related bug. Hence, here is documentation on potential root causes:

Booting

Display Issues

General Issues

Input Issues

Reporting a confirmed X bug to Launchpad

Initial filing of the report

First, please install the package xdiagnose.

Next, ensure you click the Yes button for attaching additional debugging information after running the following via a terminal:

ubuntu-bug xorg

Include developer information in your report

One will want to answer the following questions in order for a developer to address the issue:

  • 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?
