[Trisquel-users] oopsie daisy

[binzipped]

I apologise if this sequence of dumb decisions and my lack of memory makes  
you cringe, mad or have any other negative response.
So a couple of days ago my laptop ran out of power whilst i was playing a  
game. My computer was still on but i couldn't do anything; the screen was  
black. I decided to charge it. After 10 minutes, i saw no effect, so i turned  
it off and on again: It worked perfectly fine! I went on to do my regular  
buisness on it, including changing the permissions and possibly the owner and  
group of many (almost all) of the files in /bin, /sbin and /usr and the  
directories thereof. I then suspended the computer and went to bed. The  
following day, (i'm pretty sure) my computer was out of power again. After a  
brief moment charging, i turned it on. The normal loading screen (the one  
with the semi-transparent Trisquel logo and the default background) is shown  
like normal, but then the screen just goes black, even though i have plenty  
of power.
Help please!
