Hello,
I just noticed that I have a higher CPU usage on when I log out and the PC is on the login screen than when I am logged in and doing nothing (see the spike in the screenshot). This results in about 15-20W more energy consumption (~80W instead of ~60W). Has anybody else noticed that?
ROME 24.12
KDE
Are you using the AMD Ryzen-specific version of ROME?
No, normal one on an Intel CPU

Ok. I asked because I am using the Ryzen-optimized version of ROME and my fan is constantly running at high speed even when my laptop is idling. Hopefully someone else can read this thread and offer some help for you.
Just to be sure, is this happening on the login screen or the lock screen? What login manager do you use?
@LeeTalbert I would guess SDDM since he appears to be on Plasma.
I’m sitting here wondering how to test it and all I can figure is from the SDDM screen, switch to another tty and login to run htop to see what is running.
Pretty sure I read about that being a KDE issue.
Can’t say for certain, and unfortunately I can’t post the link to the bug report.
But it’s definitely not unique to OMLx.
Edit: Allowed to post links now.

Yes that’s default setting in Discourse for security and antispam reason for just registered users, as one can well understand, unless admins (considering trusted) manually elevate the user level before it’s automatically changed.
I suppose it’s not different -more or less- with other forum platforms.
Hi.
Yes, that’s what I thought, and it is most certainly appropriate to combat spam.
Lock screen and the default login manager (how do I see that?)
Today I don’t have this problem. I don’t know why. I will keep an eye on it and report back if it happens again.
Thanks for the help up to this point.
As WP said earlier, it is safe to assume that if you are on Plasma then you are using SDDM as your display manager. As asanDD said, this is a known issue with SDDM. There are some config changes that might fix it for you, but save a backup of configs before changing anything.
Add the following to /etc/sddm.conf
[General]
GreeterEnvironment=QT_QUICK_BACKEND=software
I haven’t had this issue anymore since then. My power consumption is a lot better overall. I am now sitting on ~15-20W when idle on desktop or on the login screen. I don’t know what fixed it. Probably the distro upgrade. Can’t think of anything else.
Either way, this is solved. Thanks for the help.
Can you please mark it as solved? Glad to hear it’s working.
