It's mainly the size of the Xorg.0.log file, you could have removed a
few of the repeated lines at the end.

Yes, launching evtest form a VT should do it. but then you're going to
have a huge file were all the firsts lines will be normal, basically
what we are trying to find is if the EV_SYN event is still send. This
event is displayed as "-------------- Report Sync ------------" so
you should probably cut the file and remove the middle part where the
sync events look normal.

Just because non-commercial is a restriction, so it's non-free with
regards to debian criteria at least, and some other agrees with that ;)

But of course you are perfectly free to use it for your signature :)
