Suffering occasional system freezes

Hi [member=7114]ian_r_h[/member]

One quick question - is it possible to boot into an earlier kernel version to see whether the problem continues, and if so. how?

Hold down the "shift" button while booting, this will display the grub menu where you can select a different kernel to boot from. Out of curiousity, what kernel version are you using?  Open a terminal and run

Code:

$ uname -r

this will tell what kernel version you're system is using.

Would I need to boot into the latest kernel before updating system and software?

I'm not sure I understand your question but, unless you've installed a newer one, I think that "the latest" available kernel at the time LL was released is already installed in your system and it's the one it boots from, a newer version is usually installed when updating if available. However, if you want to try a new one go here: https://www.freecinema2022.gq/forums/linux...ernel/270/ 
There you'll find instructions on how to install kernel versions 4.11 to latest 4.14 as well as older ones.
By the way, I completely forgot about it but there's a tool in LL for viewing logs called "system events" or something like that, - my language's spanish - Look for it in whisker menu on system entries.

Hope this helps!
