Description
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: http://pasik.reaktio.net/fedora/f16/radeon/f16-beta-laptop-radeon-flicker-xvid.avi
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 ?
