Hi again,

Felix, Thomas and Ilya, thank you so much for the suggestions.

I see that they don't have stable packages for Stretch / Sid as of
now. Will probably try the preliminary packages for the next release
and see how it goes.

Was thinking of putting on KDE, but that's quite huge.

Will definitely be interesting to see the results of these environment
variables.

This will definitely be interesting.....this will surely give a wealth
of information, hope it's something we can interpret and use to
pinpoint the problem. I will probably try this once am done trying the
above two tests.

Thank you again :)....been in the dark for so long, now it feels like
we will finally get to the bottom of this :)

Will report back soon :)

Bye for now
