           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:
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 ?

Oh, I forgot to mention that changing the radeon "power_profile" fixes the
problem, ie doing:

echo low > /sys/class/drm/card0/device/power_profile

fixes the problem, and there's no flickering anymore!

Did this work in the past and if so, when?  Please attach your xorg log and
dmesg output.

Hmm.. I'm pretty sure I didn't see flickering in Fedora 14 (Linux 2.6.35).
Flickering starts already before Xorg is started.

I just tried Fedora 16 final TC1 (Test Compose 1) which has Linux kernel
3.1.0-0.rc9.git0.0.fc16.x86_64. The same heavy flickering/distortion problem
happens there.

I'll attach new dmesg for 3.1.0-0.rc9.git0.0.fc16.x86_64 and Xorg.0.log. 

The flickering seems to happen on these conditions:
- Laptop starts with LID closed, so BIOS has internal LVDS disabled. The laptop
is in a docking station, so there's only external DVI monitor in use.
- After Linux has started booting, I open the laptop LID, and the internal LVDS
has been turned on on clone mode with the external DVI display - and there's
heavy flickering and distrortion on the internal LVDS display.
- Distortion starts before Xorg is started.
- After logging in to Xorg and running "echo low >
/sys/class/drm/card0/device/power_profile" the distortion stops and the LVDS
display is good/normal again.

Does it work properly if booted with the lid open?

Yep, if I boot with lid open then it's fine - no flickering. I just tried
multiple times with lid open.

I just tried with the latest Fedora 16 Final RC1 (using Linux 3.1.0 final), and
I noticed the LVDS flickering actually happens *sometimes* also when booting
the laptop with lid open. So it's not actually always related to opening the
laptop LID.

> I just tried with the latest Fedora 16 Final RC1 (using Linux 3.1.0 final), and

Same here on Acer Aspire 7560G (A8-3500M - Radeon HD 6620G) with Kubuntu 12.04
Beta 1 and external HDMI display (selected as main in xrandr settings). I
didn't try yet boot with disabled LVDS, but I indeed have flickering on LVDS in
some use-cases. For example every time when I use "carousel" KWin feature for
switch between applications by Alt+Tab.
Issue is reproduceable even when I boot without external display.

The interesting thing I notice: issue reproduceable only with OpenGL version of
KWin. I never can get it reproduced with OpenGL ES version of KWin.

Alex, I have the same issue or I need to fill separate bugreport?

Probably a separate issue.  Please file a new bug.
