Re: Sddm cannot find breeze theme

(Snipped previous messages for for length)

I wanted to give an update on this in case someone searches the mailing
list archives in the future. 

In the last build, I resolved issues with the sddm greeter by symlinking.

I rebuilt BLFS from scratch on a much faster computer. 
This time I went strictly by the book using /opt/kf6 and
/opt/qt6 as prefixes. I still ran into the same issue of missing breeze 
components. So I wanted to find a better solution as I understand
that in some cases symlinks generally mask a deeper configuration 
issue without fundamentally addressing the problem.

Looking at the git repository for sddm, I think I found that the 
fundamental issue is that sddm appears to use its own environment 
variables, and so either does not check /etc/profile, or doesn't 
understand BLFS's added pathappend function (or both).

However, /etc/sddm.conf does also allow you to manually set the 
greeter's environment variables, and so I was able to manually set 
$PATH, $XDG_DATA_DIRS, $XDG_CONFIG_DIRS, $QML2_IMPORT_PATH, 
and $QT_PLUGIN_PATH.

One symlink seemed to be requited, linking /opt/qt6/include/Plasma 
to /usr/include/Plasma. 

That seemed to fix most of the greeter's issues. 

I am, however, still trying to hunt down why the greeter lacks permissions
to allow me to sleep/restart/poweroff, and it's taking a while to
narrow down since most resources assume one is using systemd.

Being new at this, I still cannot rule out that I've made some dumb
error on my part twice, however one bug I found with the blfs book is 
in the sddm-0.21.0 instruction:

>In order to see the theme without leaving the session, issue:
>sddm-greeter --test-mode --theme <theme path>

I believe "sddm-greeter" should be "sddm-greeter-qt6" in a QT6-only build
like BLFS.

Cheers,
Sicarine
