Really like KDE Neon Plasma but for some reason, it just won’t wake up from sleep mode.
Here below is last response from someone who apparently found a solution:
“I was experiencing a similar issue, from not waking up down to the double hard restart to get back to a usable PC.
Based on a comment on programing.dev’s linux community, I set System Settings > Display & Monitor > Display Configuration > Color profile from None (the default setting) to Built-in, for both of my two monitors.
Didn’t want to cross-post but, not satisfied by the non-solution and worried about getting nasty remarks from that other forum… felt this place to be more “neutral” ground.
Have tried many KDE based distros, and KDE Neon Plasma is the only one to have this issue (for me).
I have no idea, because I have never used sleep, but I would be experimenting with the power saving settings that affect screensave and hibernate and sleep.
You dont get many settings with the GUI, but there is a file… I think from memory it is elogind.conf or maybe logind.conf in /etc. There are dozens of settings in that file that affect things like the way sleep and hibernate interact with the lid switch on a laptop, etc.
I suspect that one of those settings needs changing.
Try /etc/login.d directory?
Maybe systemd is doing another takeover.? See if you can find a relevant service?
Try /etc/systemd/logind.conf
Try ps ax | grep login . Does it find logind running?
We have to solve this. An OS that sleeps permanently is unusable.
Have a look at this topic

Update : I found something
" The /etc/sddm.conf file is where the configuration for the SDDM login manager is stored on KDE Neon, although many settings can also be managed through the System Settings application under Startup and Shutdown > Login Screen. "
and
" KDE stores sleep configuration files in
your user’s configuration directory, primarily in ~/.config/, and specifically, the power management settings are typically located in ~/.config/powermanagementprofilesrc. Older or less common settings might be found in ~/.kde/ or ~/.kde4/ directories, though ~/.config/ is the modern standard. "
Hey, what are they doing configuring a system-wide thing like sleep in users home directory? It is not like you can sleep one user’s part of the system? Crazy.
