Basically I run my own spin of opensuse built with kiwi with minimal gnome environment (no patterns).

I noticed this problem on bare-metal modern hardware (i5 - 4th and 6th gen) it doesn't occur on kvm virtual machine as I experimented with this as well.

Haveged is not required on Fedora and Arch to run GNOME on the very same hardware, that's why I filled this bug.

Reproduce the hanging login and then in an TTY do: ## cat /proc/sys/kernel/random/entropy_avail ## If response is anything less than 100-200, you have a problem with entropy. In any case, still not a GNOME issue :-) It will be for the base-system or Kernel people to answer. -- You are receiving this mail because: You are on the CC list for the bug.

No Haveged: At startup: cat /proc/sys/kernel/random/entropy_avail 52 After a while of usage: cat /proc/sys/kernel/random/entropy_avail 897 ---- Haveged: At startup: cat /proc/sys/kernel/random/entropy_avail 1202 After a while of usage: cat /proc/sys/kernel/random/entropy_avail 2316 Anyway, thank's for the explanation, I think haveged does a lot for my entropy (especially during login process), I'll keep it then ;) -- You are receiving this mail because: You are on the CC list for the bug.
