Asus Laptop (R558U) does not suspend after upgrade to 24.04

[Leonard Peris]

I was previously running Ubuntu 23.10 on my laptop. I performed a `dist-upgrade` about a week back. Since the upgrade to 24.04 my laptop does not suspend - either by pressing the power-key (previously working on 23.10) or by using the GNOME system power menu.

My laptop has integrated Intel graphics as well as NVIDIA GeForce 930MX (GM108M), but i haven't installed proprietary video drivers. It is currently using xserver-x-org-video-nouveau as the video driver. My system reports as running a wayland session, but I find the above X.Org detail confusing.

There is currently one inhibitor running `gsd-media-keys`.

I filed a bug under systemd as ubuntu-bug would not let me file a bug without a package name. If this is incorrect, please change the package-name as appropriate.

I would like to restore previous functionality - system suspend on command.

I'd be happy to provide additional logs and to troubleshoot any possible fixes.
