Package: base
Severity: normal
A report was filed on Launchpad against Ubuntu Lucid reporting that the kernel
upgrade from Karmic to Lucid
introduced irregular sync flashes on the screen. cf.
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/538648.
The problem reported there is also seeming to affect Debian Squeeze.
The upgrade to Ubuntu Maverick has caused the problem to go away when using
that OS. Sadly though the
problem still afflicts Debian Squeeze. Is there any way the information from
the Ubuntu-oriented
investigation can be applied to Debian Squeeze?
The flashes are really, really irritating.
Thanks.

Thanks! Marking accordingly.
Maybe something in the "drm/i915: use GMBUS to manage i2c links"
series or something like "drm/i915: Disable FBC on Ironlake to save
1W" or "drm/i915: Fix updating FBC" did the trick. If someone has
time to bisect the fix to track down what patches to backport, that
would be nice.
