flaky resolution and aspect ratio

I'm not entirely sure of the resolution settings, but they're flaky.
Quite often the aspect ratio seems off like when they broadcast old
movies for tv the image is stretched vertically (or, like viewing HD tv
on regular tv). Often logging out will fix the problem by, I presume,
restarting x windows.
How do I log or capture this? I suppose I can grab a screenshot, but
surely in dmesg or similar there would be an event along the lines of
"not detecting video card correctly, trying defaults..." (assuming that
to be the source of the problem).
I don't see how it's a matter of changing the screen resolution in X
windows, since quite often, the resolution and aspect ratio are fine.
Perhaps it's flaky hardware?
Or, maybe a driver that's not always loading correctly? Although that
would be inconsistent with logging out fixing the problem. A few days
ago logging out and logging back in stopped fixing it, and it's annoying,
anyhow.

Also, I tried to disable dontZap, but it still doesn't seem to work.
