I'm going somewhat crazier than usual trying to use Thuderbird Mail because Thunderbird has blown up again, lost my password, won't let me put in a new one, the on-line instructions for fixing it (using Windows) don't seem to work anymore--I think they've "updated" it. I want to use KMail, but it wants KWallet, and I have been defeated trying to install that. Trying it cold didn't work, so I just tried https://duckduckgo.com/?q=short+guide+for+pam_kwallet&ia=web, from benediktg, ran sudo zypper pam_kwallet, and very carefully modified the three files it requests--/etc/pam.d//passwd, /etc/pam.d/login, and /etc/pam.d/sddm. I checked the "new" versions carefully, and I'm really pretty sure they agree with those posted. I put an icon on the desktop that's called "KWallet/Manager," by selecting it from the bowling ball, but when I click on the icon, nothing happens. Any helpful advice welcome. --doug PS--this mail routine from optimum.com is NOT user-friendly, in my humble opinion.
