@Mounir,
Thanks so much for your time. Just a couple of notes regarding grub and initramfs.
-
after updating grub run:
sudo update-grub -
the update-initramfs options I typically use are:
sudo update-initramfs -u -k all
Just to make sure all installed kernels get updated. I usually only have a couple but it’s helpful.
For the “doesn’t work on ubuntu 18.04” issues, I suspect it’s a conflict between the NVIDIA driver and the Nouveau driver due to both being installed at the same time. try googling nouveau conflicts with nvidia to see if anything helps. I’m also having suspend, hibernate, resume issues on my 18.04 based distro.
It’s unfortunate that the distros seems to have removed all the configuration to support suspend, hibernate, resume rather than just allowing users to turn it off via gui configuration options if it doesn’t work for their computers. This causes the rest of us to have to figure out how to get it all put back in and up to date with current versions of what ever power management system is being used by our distros.
