one question to your HDD/SSD-access:
I noticed that Solus-Budgie is accessing my HDD more than once every minute.
Even after a boot and even if there is no programms running, only the desktop, the HDD light is blinking frequently.
I remember that Ubuntu-Gnome (which i had before changing to Solus) had the same behaviour.
So i asked myself, is this some background-behaviour that comes from the Budgie/Gnome-Desktop, or is this related to the Linux-Kernel?
And is the KDE Plasma desk also accessing the disk frequently, when there are no programmes running?
