This is mostly commenting on what I have recently noticed.
1: Using “lightdm”
For various reasons, I switched to “lightdm”. That worked fine, and I logged into Plasma. But, shortly after login, I was prompted for the password for “kdewallet”. This was a surprise. I am using “kwallet-pam” and it is supposed to automatically open “kdewallet”. Apparently that does not work when using “lightdm”. I will probably report this as a bug, but I’ll wait a day to see if there are any comments here.
I normally use “gdm” or “sddm”, and those work fine with “kwallet-pam”. For testing, I also tried “xdm” and “kdm”. And both of those also are fine with “kwallet-pam”. Only “lightdm” is giving problems.
When I run
update-alternatives --config default-displaymanager
to change the display manager, there is an option for “Console”. And I had no idea what that was supposed to do. So, while experimenting, I decided to give it a try. This was with Tumbleweed in a VM.
After switching, I rebooted. And it never finished booting. The messages showed a failure to start displaymanager, and a waiting (no-limit). To me, this seems like a bug. Either “Console” should not be an option, or I should at least be able to finish booting if I select that option. Again, I’ll wait a day to see if there are any responses, before I decide whether to post a bug report.
NOTE: To recover, I did a forced power-off. And then I rebooted, adding a “3” to the end of the boot command. That got me to a command line boot, where I was able to run “update-alternatives” to revert to using “sddm”.
