Odd error this evening

Greetings all; As those of you the the USA know, Southern WV took a beating from the weather last night and today. Heavy rains, high winds combined to kill the power for about 25% of the states population, and threaten to drown quite a few. My own automatic 20 kw nat gas standby ran from about 3:20 Thursday morning until a final restart shortly after 18:00 local. So I am busy catching up on my email, when apparently my ups did not properly restart after one of the inevitable short term power up's when the line crews are closing circuits to see if they fault again because there yet another down tree laying on the lines a half mile around the corner. So I'm typing away on a message reply when the screen goes black, the ups has a low battery and kills the load. Restarting the ups was a matter of holding down the power button for 3 or 4 seconds, followed by a trip to the tower to tap its power switch. Everything solved as soon as its booted, right? Wrong... No /usr/bin/X to be found. I had to totally apt-get install --re-install all of the Xorg-server stuff, 35 or 40 packages, to get the missing /usr/bin/X. That may not have been the only package that was nuked by the untimely powerdown but I've no way to verify that. But why should a powerdown as unceremonious as pulling the plug, have deleted /usr/bin/X? It doesn't grok at this site. Clues? Thanks.
