I tried to install Discord via pacman, aur, tarball, and then via snap, but all of them kept at STARTING page for a very long time. Is it normal? If not, how could I fix it?
Discord is an awful program that doesn’t really function very well on Linux.
You can try the Lightcord package.
Should take no more than 15-20 seconds to start. Electron programs are slow like that.
Oh and welcome to the forum.
