Beside few package signature errors (solved by unable checking), Gnome DE, Dolphin, Libreoffice, Gimp, Scribus, etc. were installed and works well. Only gnome-tweaks doesn't start.
Is it depending on a missing pkg?
Thank you!! I was viewing Arch package page, and suddenly new update 3.34.0-2 appeared. Installed it manually, and works fine.
As I mentioned in my first post, impressed by the the performance and snappy respond. Non-systemd does it which brought me to antiX Linux. Now seeing in Artix slightly faster respond with all apps, confirms it.
Starting with Arch Linux in 2002. Later when systemd was introduced made it easier to maintain, but there was a performance loss what is noticeable today. Good know the "originality" was kept.
