NS8 on Debian-12 // Avoid sddm-greeter to have high CPU usage

Hi all,

I installed NS8 on a Debian-12/Plasma and I noticed that sddm-greeter takes from 8% to 14% of the CPU if I don’t login to Debian-12…

Ref: Avoid sddm-greeter to have high CPU usage - DEV Community.


At the end of the file /etc/security/pam_env.conf add the lines below.

# Avoid high cpu usage with sddm-greeter
# https://dev.to/brisbanewebdeveloper/avoid-sddm-greeter-to-have-high-cpu-usage-2m2g
# https://github.com/sddm/sddm/issues/323

I tried the cluster-admin login, etc and all is working as it should be.

If somebody else can confirm.
