You can't post attachments of any kind, but you can put them up on a 
website of your own and provide a link.

If this were happening to me, I would first suspect that webmin/cups was 
just something that triggered the problem but not the root cause.

What graphics card do you have?  Is it seated properly?

If it's an NVidia, are you running the Xorg (nv) driver or the NVidia 
driver from ports?  In an earlier release of Xorg I was forced to switch 
to the NVidia driver because the xorg driver didn't work, caused screen 
corruption and lockups.  (Mozilla triggered that, but I don't blame 
mozilla).

 From you PR note I see that your are running an Nvidia card, so 1) try 
upgrading Xorg as it seems to be out of date - you say you have 6.8 but 
6.9 is the latest 2) If that doesn't help then try the nvidia driver.
