ijustupdatednowwhat's questions

After a clean install of Ubuntu 16.04 LTS, I am experiencing very slow shutdowns compared with 15.10. There seems to be one of two processes that hang upon shutdown. Startup is not affected at all. When pressing (esc) the following are shown. Either:

"Stopping thermal daemon services" hangs, or "A stop job is running for remote CUPS printers available locally", before a timer to 1 min 30 seconds is up, after which the machine finally shuts down.

Are there any other people experiencing this? This is most odd. What could be the reasons behind these two hangs?

I have just updated (through Software Update) to Ubuntu 16.04 LTS from 15.10. There are random instances of screen flickering throughout usage. After noticing this issue, I installed Compiz Config Settings Manager, selecting Force fulls screen redraws (buffer swap) on repaint, which did nothing.

Is there any way this could be related to compiz settings or is this another issue?

EDIT: not fixed after clean install, upgrade to kernel 4.5.2, however screen flickering is reduced, it is every now and then (10 minutes apart). I will see if upgrading to kernel 4.6.0-994-generic will fix this.

EDIT: fixed as of kernel 4.6.2 generic, currently running 4.7.2 without any issues.
