           Summary: radeon lvds panel heavy flickering after opening
                    laptop lid (Mobility Radeon HD 3650)
           Product: DRI
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: pasik@iki.fi


I'm using a laptop with Mobility Radeon HD 3650 (HP EliteBook 8530p). Normally
the laptop is in a docking station, so I'm only using the external DVI monitor.
The laptop lid is closed and the laptop internal LVDS panel is disabled while
in the dock.

I just tried the new Fedora 16 beta liveCD on my laptop. Fedora 16
automatically enables all display outputs, which means also the internal LVDS
panel gets enabled, even when my laptop lid is closed. And the gnome desktop
gets extended to both the DVI monitor and internal LVDS panel. This means I
need to actually open the laptop lid to see the gnome menus, because they're
displayed only on the internal LVDS panel. This is a configuration/defaults
issue in Fedora 16, and that's not the bug I'm reporting.

While opening the laptop lid I noticed the internal LVDS display is heavily
flickering, and the screen is totally unreadable. 

I've uploaded a video of the heavily flickering LVDS panel here:

Fedora 16 beta is using Linux 3.1.0-rc6. dmesg available here:
http://pasik.reaktio.net/fedora/f16/radeon/f16-beta-laptop-radeon-dmesg.txt

I tried rebooting the laptop a couple of times, and it seems the flickering
doesn't happen on every reboot.. but it happens on *most* reboots. Flickering
starts already when kernel is booting, before Xorg is started.

Any more info needed ?
