I am willing to give "Bartosz" some slack on this one, at least up to a
point.  I did, after all, report a bug for hardware that the programmers
likely consider "obscure" or "obsolete"; not many people have P4m laptop
systems with Radeon Mobility anymore.  It does seem rather clear that the
problem is video driver related, so if there no Ubuntu programmers have
hardware with this video card in it, testing the bug can be difficult.

However, I do disagree with the label of "invalid".  It is trivial to find
other accounts of the same problem online, so it certainly does exist.  It
appears I was just the first one to report it here on launchpad.  The tag of
"Won't fix" makes sense at this point as the configuration does not seem
important to ubuntu developers at this point in time, and "incomplete" I
cannot argue against either as I personally will not be able to provide the
files that were requested.  However calling the bug "invalid" seems a bit
heavy-handed.  Perhaps someone else with this problem will find this bug and
provide the requested files if they have not already deinstalled ubuntu for
an OS that works on this hardware.
