Bryce, frequency is not particularly easy to measure. Over the course of
running the *same* kernel, I have experienced this happening every 2 or
3 minutes for an hour to not happening for a whole day.

This appears to have gotten worse for me with today's updates and -18. I
used to only see it a few times a week but now it seems to be happening
a few times a day. Should we try the i915.powersave=0 thing?
Sorry for the anecdotal evidence but I have no idea how to troubleshoot
or reproduce this.
Does booting to the earlier kernel make it occur less frequently?
Perhaps this is a kernel drm bug.

Anecdotally, there does seem to be less of this flickering now, but I
still get it occassionally. I'll see if I can get some actual data and
report back.

fwiw I've not noticed any more of these flashes for a few days, although
I hadn't set the powersave option.

I have also been having this issue on a Lenovo S10. I have attempted to
resolve by adding in the requested options into the kernel boot however
it still persists. Below is a link to a video if the issue. The screen
will flicker, blackout, and tear. the video below shows the tearing.
Russel, can you please run the command apport-collect 538648? it will
automatically attach all of the logs we need to look into this to the
bug.

When I first installed Lucid on my T500 I believe everything seemd to be
fine with the display. Recently though the screen has started giving

Thank you for that. Now have you tried booting with i915.powersave=0
added to the kernel command line in grub (after it says quiet splash) to
see if it fixes your issue or not? That will help narrowing down the
problem.

I've just marked bug #534894 as a dupe of this one, since that too is filed
against the intel package and describes infrequent flickering that is comprised
of extremely brief corruption of part of the screen. I think we're also all
running fairly recent Intel chips.

I am experiencing the exact same problem on my Lenovo Thinkpad W500. My
video card is the ATI Mobility Radeon HD 3650 hardware, however. I am
also getting white (frequent but not constant) horizontal lines
appearing and disappearing randomly all over the display.
I'm guessing this could be a

Adding nomodeset to the kernel parameters seems to have fixed this for
me.
Probably best not to mark this as a dupe of 538344 just yet since Russel
reports he is seeing it with an Intel card...?
538344 does mention that kernel 2.6.34 pre rc1 seems to fix the problem.
Maybe Russel could test with
