Fade-to-white-picture No.1

On my new Sony Vaio laptop (VPCEC3L1E) the screen fades to white
(with backlights on, i think) instead of simply blanking out.
This can be reproduced by running "xset dpms force off" or
by simply waiting until powermanagement kicks in.

The graphics card used is a radeon 5xxx(?)
(01:00.0 VGA compatible controller: ATI Technologies Inc Device 68e0).

This happens on console and in X.
I'll attach some pictures showing the issue.


Thanks for any help!


PS: I hope i did choose the correct product/component for
this type of bug.

Did this used to work previously?  If so what kernel version?
Comment 9 Alex Deucher 2010-12-12 16:46:00 UTC
Please attach a copy of your vbios rom following these instructions:
(as root)
(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom

No, didn't work. Screen still becomes white on
'xset dpms force off'.

I really hate to bump, but are there
any news/updates about this issue? Should i
post more infos/logs?

Is there _anything_ i could do to make
this work? _Anything_ i could test?


Additinally a second problem showed up:
After suspending the laptop the screen (sometimes)
flickers a lot. This only goes away if you do a
complete poweroff.
Should i file a new bug report or could this 
also be related to the actual problem?

Thanks in advance.

I have the same problem on eMachines E640G laptop with the same integrated graphics (PCI ID is the same). I remember having this problem ever since the Evergreen support started to work. Currently I'm using kernel 2.6.38-rc5+
