I want my notebook (Lenovo-U31-70) to be able hibernate/suspend and i can't do that. I think that i test all the basic solutions I find and nothing works... I need help to understand what it can be.
I test all the ubuntu versions (16.10 - 19.04) and nothing works. I hate to use windows but i need to use because of the hibernate function that windows has working.
I have dual-boot win10/ubuntu 19.04 with a 8GB ram and a swap with 11GB
So on this last 3 versions I have done the following. manually test the option.
$ sudo systemctl hibernate
and of course doesn't work, the display gets black and the power button on, but some times restarts it self. So need pass to the configurations.
$ cat /etc/fstab $ sudo gedit /etc/default/grub $ GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=/dev/sda7" $ sudo update-grub $ sudo reboot
After the above changes the result has some changes but not what i want. The hibernation starts and our notebook shutdown our stays with the display black again.
When the shutdown ocours the restart doesn't resume but starts a new session.
I don't now what i can test more.
I have test other linux distros the Fedora and the hibernation occours without any configuration, but the resume it's the same starts a new one.
