Package: metacity Version: 1:2.8.8-1 Severity: normal
When I plug my laptop (Dell Latitude C640, video card Radeon Mobility 7500) to its docking station with an external monitor attached, even if I have the "PanelOff" option set in my X config file, the laptop panel's backlight turns on during the Gnome login process. (Without "PanelOff", it turns on as soon as X starts.)
This causes serious heating, especially when the lid is closed (as I normally keep it when docked); it could potentially damage the system in the long run.
I'm not really sure which package exactly is causing that, but I think metacity is the most likely candidate. Indeed, it happens when the Gnome splash screen is displaying "window manager". (I asked for advice on debian-user, but got no useful response.) I guess metacity turns the backlight on when it grabs the X display.
Error messages printed or logged: none that I know of.
How to demonstrate the problem: log into Gnome with laptop docked, external monitor attached.
Expected behavior: panel should stay off.
Observed behavior: at some point in the Gnome login process, while the splash screen is displaying "window manager", the panel's backlight suddenly turns on. However the screen remains blank.
Debian version: 3.1 (Sarge) on i386 Kernel version: 2.6.8-1-686
Hardware: Dell Latitude C640 laptop (with docking station).
Processor: Mobile Intel(R) Pentium(R) 4 - M CPU 2.00GHz
Video card: ATI Technologies, Inc. Radeon Mobility M7 LW [Radeon Mobility 7500]
/etc/X11/XF86Config-4 attached.
Thank you Gerardo Ballabio
