Xorg process takes too much time cpu

[François-Denis Gonthier]

Thank you for taking the time to do this analysis.  While I agreed his
bug report was exceptionnaly vague, I was also saddened by the kind of
answer he got from the list.

One could check if Ubuntu Studio has updated the Nvidia driver
recently.  The UbuntuStudio repositories seems to be down right now so
I can't check.

If that is the source of the problem, another update could have solved
it already.

Ubuntu has no service enabled by default so this is very unlikely.  A
newbie could still have installed a mail server as a dependency of
something else though.

I don't know about services enabled on Ubuntu Studio, but the scope of
the distribution makes me think it's unlikely they have any service
enabled.

I somehow doubt he'll write back.  His problem might even be fixed
right now.
