Hibernate is not working since 3 weeks

thats already over 800MB in size

you had them installed before already, so i had given you the command to properly reinstall all installed kernels.. May i saw it wrongly uninstall 2 at least hardened and zen or hardened and default no clue what you prefere?

sudo pacman -R linux linux-headers linux-hardened linux-hardened-headers this would leave you with Zen and LTS kernels

800Mb Is-it normal ?

Yes, It’s what I do !
I let only Zen not LTS kernels

Thanks for your advise !

At this point, I reflect on install grub…

At this time I use an kernel LTS but hibernate is always impossible !

Must I reinstall nvidia-dkms after this choice ?

Thanks a lot

In principal no. But please show the output of commands

inxi -Gza
pacman -Qsq linux headers
pacman -Qsq nvidia

inxi -Gza

Thanks a lot for your help

Are you using linux-zen?

If other kernels also fail, then I’d suggest looking at the Arch wiki for more details (like settings etc.) for your machine.
One thing might be the envycontrol, maybe another GPU switcher works better. But this is just a guess.

The only way really working for me was to creat a shortcut.
System Preferences → Create Shortcut → Add New → in the command line: /usr/bin/systemctl hibernate → Add, and then select a keyboard shortcut for it, for example CTRL+L.

I close Do this by terminal and meet the issue !
