l'affichage en résolution maximale du Samsung 20" n'est pas correcte:

[Bigan Michel]

Binary package hint: xorg

Écran samsung 20" correctement détecté mais affichage correct dans toutes les résolutions sauf la plus haute 1680x1050 :
- le bureau est noir, seules les barres de tâches et de menus sont visibles ;
- les fenêtres des applications paraissent correctes mais si je les maximise elles deviennent noires comme le bureau. En promenant doucement la souris dans la fenêtre, les bulles d'aide apparaissent, un clic la fenêtre redevient noire mais quand on réduit la fenêtre elle est a nouveau opérationnelle !

Avec mes remerciements en espérant vous avoir été utile.

[Bryce Harrington (bryce)]

Thank you for seeking to improve Ubuntu. It seems you have filed a bug
against X using the new System Testing utility. Unfortunately, this tool
is filing bugs without collecting sufficient information to properly
diagnose the issues. I wish we could reply to every report to guide you
to gather the correct information, but it happens that so many people
are using this testing feature to file bug reports that we simply cannot
keep up with the influx. I'm replying in bulk so I can get everyone
pointed into a direction most likely to result in getting you a useful
workaround and us a complete bug report that can be solved.

Most of these problems describe issues that have documented
troubleshooting procedures, so perhaps the most helpful thing I can
do is point you to them:

  http://wiki.ubuntu.com/X/Troubleshooting

These guides explain why things break the way they do, and in some cases
provide workarounds.

I would ask that you first go through the appropriate guide for your
problem, particularly if you are having problems with resolution,
crashes, fonts, or blank screen issues, and then file a bug report using
the following command:

   ubuntu-bug xorg

This collects more detailed information than the System Testing tool
does. Please also write a detailed explanation, indicating when you
first discovered the problem, analysis steps you've done, workarounds
that work, and so on.

Or, if you suspect the problem has something to do with the way the test
script itself is working (such as if Ubuntu worked fine until you ran
the script), then file the bug against the test suite:

   ubuntu-bug checkbox

Thanks again, and good luck!
