Thanks, that log is good. The only real error I can see is that your GPU
doesn't support some feature gnome-shell is trying to use:

But that GLSL trouble might not be the real problem. If you look at the
timestamps you can see there is only 4 seconds between the GLSL errors
and the machine being told to shut down. So I suspect you're not waiting
long enough for the machine to start up and killing it in the middle of
the start-up process (which seems very slow, but still seems to be
working). Please try waiting 15 minutes next time and send us a fresh
log from that.
