A little background info, i had issues playing 10bit video on my laptop. Playback was choppy and full of grey pixelation on vlc. so i decided to install intel graphic drivers.
After installing their update tool(v 2.2), i had issues the dependency libmesa not being satisfied(i had a lower version) so i ran sudo apt-get dist-upgrade
then i was able to update to intel graphics drivers successfully. But once i restarted my system. Ubuntu would log me out 10~15 seconds after logging in.

here are the libs the graphics driver installed https://01.org/linuxgraphics/downloads/2016q2-intel-graphics-stack-release
I've been at this since yesterday and i've tried everything i've seen on previous questions and ubuntuforums from chown-ing .Xauthority, purging and re-installing xorg and x-server, even writing the default contents of /etc/X11/xorg.conf.
All to no avail, please this is my dev laptop. How do fix this problem. I'll happilly provide any other info you need. This is my last hope - i have a lot of important files on this laptop and i spent a lot of time customizing and installing and configuring my dev environment. I'd really prefer not to have to re-install ubuntu.
thanks.
