I can't suspend my system

Welcome to the forum! :vulcan_salute:

Please update your system first. Your system and your kernel are already hopelessly out of date. This below is what the lsb_release and uname commands should yield… :point_down:

[nx-74205:/dev/pts/3][/home/aragorn]
[aragorn] >  lsb_release -a
LSB Version:    n/a
Distributor ID: ManjaroLinux
Description:    Manjaro Linux
Release:        23.1.3
Codename:       Vulcan

[nx-74205:/dev/pts/3][/home/aragorn]
[aragorn] >  uname -r
6.1.71-1-MANJARO

Manjaro is a (curated) rolling-release distribution and must be kept up to date — we cannot offer any support for systems which have not been updated in a long time, or which have only partly been updated.

Please also take the time to read the following short essay… :point_down:

If for whatever reason you do not or cannot keep your system up to date — and maintained, because you probably also have lots of .pacnew files to tend to — then you will be better off switching to a point-release distribution such as Debian, Mint, Ubuntu, Mageia, AlmaLinux, Rocky Linux, et al.
