Thanks Joseph. I have tried to do as you suggest, but hit a problem installing 4.18.0-041800rc6. Two of the downloads install, but the third fails and my Linux skills are insufficient to work out what to do next. If you are able to make a suggestion I'm happy to have another go.
If so, here is what I know: The first thing to check is that the packages I attempted to install were the correct ones: linux-headers-4.18.0-041800rc6_4.18.0-041800rc6.201807221830_all.deb linux-headers-4.18.0-041800rc6-generic_4.18.0-041800rc6.201807221830_amd64.deb linux-modules-4.18.0-041800rc6-generic_4.18.0-041800rc6.201807221830_amd64.deb One of the headers failed to install, with an error message implicating Nvidia, see make.log from /var/dkms/nvidia/390.48/build/ attached. A summary of the /boot folder is attached (grub18.txt) showing what has installed. You can also see that the kernels currently being provided by Linux Mint (LM) are a good deal earlier eg 4.15.0-29. Also of relevance might be two sections of the Mint 19 release notes, about trackpads and about freezes on booting due, in the case of this box, to the Nvidia graphics card: https://www.linuxmint.com/rel_tara_cinnamon.php Once the first LM installation is done, when LM release new kernels the Nvidia issue does not occur. This is a live system used eg to maintain my PERL server-side website applications, so I need to take some care. What should I try next?
