Laptop takes 30 seconds to resume from sleep in KDE Plasma (issue persists across different OS)

I’m facing an issue where my laptop takes about 30 seconds to resume from sleep mode in KDE Plasma. I suspect the problem lies with KDE Plasma itself, as I’ve experienced this behavior on multiple operating systems.

ROFL - ok, this is what’s called a ‘logical fallacy’ - or maybe a ‘false cause fallacy’.

How is it possible for a problem you experience with your computer running KDE can also persist in Windows or some other operating system?

If the problem exists with multiple operating systems, then neither KDE Plasma, nor Linux are to blame - the issue is evidently with your hardware or firmware.

The OP presumably means multiple distros, but maybe even Free BSD, that would count.

Perhaps you are hitting the same problem as in this thread:

Sorry, I wrote a little wrong. I mean, the problem is precisely with Linux distros WITH kde plasma. I’ve also tried chat gpt tips like modify the grub file, but it still didn’t help, so I’m asking here

Ok, and this happened with ‘multiple distributions all running KDE Plasma’.

  • You did not state if the same occurs with XFCE, Gnome, Cinnamon…

It is possibly a hardware or firmware issue, you could try to eliminate KDE Plasma from the equation first.

It could be your Desktop environment, or the Graphics (I always start by strongly suspecting that you’re infected with nVidia malware disguised as ‘hardware’).

Some people also forget the need for swap, and so need to verify and possibly set up a swapfile:

➤ swapon --show
NAME       TYPE      SIZE USED PRIO
/swapfile  file        4G   0B   -2
/dev/zram0 partition  16G 3.8G  1

It is also extremely important to offer a reasonable baseline of information (I find that inxi -zv8 | grep -vE 'MAC|UUID|IP' generally covers most of what anyone might ask).

You also need to be very clear with other details; people often prefer to have a separate /home partition (especially ‘distro hoppers’) which means that their user data persists across installations.

I have long said that it’s generally best to install the ‘easy’ way, and to always keep a backup of /home - that way, on a fresh install you can import ONLY what you need - and leave the junk behind.

This also strikes me as plausible.

Finally, I would suggest that you take a look at your logs - and that’s something that AI can help with parsing (but also dangerously invent answers).

When using AI, I would strongly suggest a prompt to help fight the fantasies:

Respond as a neutral processor. Adhere strictly to the following:
    Provide factual, concise answers without speculation.
    Omit self-reference, prefaces, opinions, and filler language.
    Begin the response directly with the answer to the query: 

I hope this helps - though the post is now 2 days old, sorry I missed it before.
