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…
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 QT_QUICK_BACKEND DEFAULT=software
I tried the cluster-admin login, etc and all is working as it should be.
If somebody else can confirm.
