I have an Acer Aspire One AOA150 with Lubuntu 16.04.2 LTS.

After update,I rebooted and I had just black screen with strange lines,later 3/4 black screen and 1/4 regular screen,but nothing can be done.

I'm not an expert, I fund @Pilot6 solution https://askubuntu.com/questions/9454...d-update-16-04

I deleted the 4.13.0-26 kernel and then : sudo apt install linux-generic.

Now,I'm working with the previous kernel and everything is fine.

If I'm not wrong, this was the Meltdown patch and,obviously,I need it.

I'd like to understand if ,the next time,this kernel will be updated?if I did well to delete the malfunctioning kernel.

How could I have a functioning Meltdown/Spectre patch?

Thank you
