display on TV: resolution problem

[chug]

Hi,

I use a dell inspiron 1525 with 8.04 (hardy). When I plug the cable and press the Fn+crt/lcd keys, the TV display partially what I see on the laptop.

To my understanding, the resolution of the laptop change. Well in fact only the "taskbar" change (reduce), all the other windows stay wider (it looks strange). If the application (in this case movie) is wider than the supposse new resolution (shown by the taskbar size), it is not working (specially true if I ask to see fullscreen for a movie).

Any idea how to fix that?

thx by advance

I found a workaround today. I disable all gnome "visual effect" and it works (I don't know why).

To do it, go to System->Preferences->Apparence on the visual effect panel and choose no visual effect.

Note that I also install grandr that help me a lot to configure the resolution of the TV.
