I just got a new 6th Gen machine and installed Elementary OS in it. Things are a lot unstable. VLC crash, my editor Brackets crash, system hangs. Might be related to graphics? Im not using an external GPU. How can I fix this? Update the kernel? The intel graphic drivers?
I had this problem on a new 6th gen. machine (does this sound familiar to you?): Dell Inspiron 15 5559 Problem at shutdown and logout (Intel Skylake)
And it looks like it was a problem with the Intel graphics drivers. An update to kernel 4.4 solved it (almost). Here's how to upgrade: http://ubuntuhandbook.org/index.php/2016/01/how-to-install-linux-kernel-4-4-in-ubuntu/
