Bug Description
I navigated to a website in Chrome (linledIn.com) and both Chrome and Xorg started consuming around 100% CPU each (one was actually significantly above 100% but I can't remember which one).
Then I closed Chrome entirely (and I check there was no Chrome process left), but Xorg kept consuming around 100% CPU. No other process was.
I closed all applications I had opened, but nothing stopped Xorg from consuming around 100% CPU while nobody was doing nothing. I had to kill Xorg.
It might have been a complete coincidence that Xorg's crazy CPU usage started when I opened that website in Chrome, or it might actually have been caused by it, even by a bug in Chrome. But even if that is the case, if an application can cause Xorg to consume 100% CPU and then not stop even after the application has been closed, that is a bug in Xorg.
Also, something quite similar happens to me very often:
sometimes I open Google Maps in Chrome and (not every time, far from it), the same as described above happens, that is, both Chrome and Xorg start consuming a lot of CPU. However, in those cases, usually when I close Chrome, Xorg's CPU consumptions goes back to normal (and then I'm able to reopen Chrome and everything works normally).
This was the first time that Xorg's abnormal CPU consumption persisted after closing Chrome which seemed to have triggered it.
I'm not sure whether the two cases are actually caused by the same issue or not.
I know I'm providing little information but this is all I have.
Note that the issue is critical.

It looks like using Nvidia on this laptop is optional. I wonder; can you please uninstall the Nvidia driver and then tell us if the problem still occurs?
If so, then please run:
dpkg -l > allpackages.txt
and attach the resulting file 'allpackages.txt'.
