Right after installing [Manjaro Linux]
i run into weird issue.
Most of needed applications like Firefox and Thunderbird take around 10 seconds or so just to startup.
Such behavior on NVME drive is unacceptable at all.
Problem was in a serious [bug in gnome desktop] , despite the fact that i’m running XFCE desk.
Workaround for GTK-based desktops is to run following commmands in terminal:
sudo pacman -Rdd xdg-desktop-portal-gnome
sudo pacman -S xdg-desktop-portal-gtk
