System lag after Ubuntu update - how to troubleshoot & revert back?
I just updated my Lenovo X1 Yoga 3rd gen running on Ubuntu 18.10. The machine has been running great, that is until today after the update. It is extremely slow.
I am wondering how to troubleshoot and also as an alternative is there a way to undo the update?

Have you rebooted your computer to see if that solves the slowness?

I rebooted, twice. And it was still doing it. But now after restarting it again a few times it's back to normal. So, I am not sure what it was, but it is not doing anymore... As far as what I meant by slow, I mean like laggy. Lack of response or slow response, as if you were playing your favorite multiplayer game online with a high ping =)

Don't assume that an upgrade is responsible. Maybe it is, maybe it's not. Maybe you picked up a crypto-miner or other malware instead. 'Maybe' lots of possibilities.
Here's one first-pass approach to rule out many of those possibilities:
Look at
topto see what the big resource-consuming processes are.Look at
freeto see if you are swapping.Look at
df -handdf -ito see if your storage is full.Check /var/log/apt/history.log to see what was recently upgraded. Look for frequently-used applications and new kernels.
If the logfile shows that a new kernel was installed, try rebooting into the previous (older) kernel to see if performance suddenly resumes.
Review /var/log/syslog for unusual activity, warnings, and errors.
If NONE of these provides any clue, then it's time to rule out hardware: MEMTEST, SMART Test, and the like.
My 18.10 is as fast as ever, so it's not a universal problem.
