Started Evolution, had to retype Hotmail password, everything else normal.brilliant! worked like a charm thanks.
my abbreviated procedure, since I don't use the gnome-keyring for anything (except apparently chrome...)
1. install libpam-gnome-keyring
2. delete ~/.local/share/keyrings
3. logout and login.
Started Skype, had to retype Skype password, everything else normal.
Started Chrome, almost never use it but my settings and history seem intact.
So deleting my existing keyrings didn't really affect my applications. And now I don't see keyring prompts anymore so big win!
Thanks fehlix and dolphin_oracle. I think you solved this keyring nonsense for MX users. An anvanced user who for some reason wants a separate keyring password will be able to set that up. 99 of 100 MX users most likely are happier without keyring prompts.
