Bug Description
Ubuntu 10.10
Package: Don't know (Probably video driver)
When I connect an external monitor to my Dell Vostro 3300 laptop, I get the image in the monitor, but the image trembles a lot. I try all the available resolutions and refresh rates. The problem is worst in some configurations than others, but only in 640x480 resolution at 60Hz the tremble disappear. Obviously that resolution is not usable at all. I also tries changing the VGA cable and I try with three different monitors, but the problem is the same.
Just for test I try to connect an external monitor using other O.S. (Windows 7), to discard the possibility of hardware malfunction, but in that S.O. everything works fine.
I contacted Dell support and they refuse support for more O.S. than Windows 7, but they mention that in that Windows 7 this problem is commonly related to video driver. I asked for a Linux driver, but get a negative answer.
