Love the picture–the world’s first military-grade camera?
I’m not sure of your level of experience, but a couple of useful tips came to mind when I found out a kernel change helped you.
1-download Grub Customizer:
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
This graphic app allows you to make changes to grub. In your case if you could check the box “previously booted entry” it will default to the kernel you know will work. You can continue to stay current by installing new kernels and, who knows, a future version of 14.15 may work like a charm.
(Also Grub Customizer allows you to add images to your boot screen. In the terminal paste:
sudo cp -i ~/my_background.tga /boot/grub/linuxmint.tga
Grub Customizer allows you to activate these images, but you have to browse. Look for them in usr/share/images/grub.)
2- I’m not positive this will help you but in Mint 18.X “Update Manager” has a tab “Linux Kernels”. From here you can remove and install kernels directly.
3- Since installing Mint 19 (which uses 14.15) on my sacrificial laptop, I noticed several oddities. I don’t think there is anything untoward is happening here–I think some kernels just turn out to be funky.
