It turns out that the problem I described below was due to the
wrong NVidia driver being loaded. It appears that I now need to
use the -390 version rather than the default -440 version. So now
sddm-greeter doesn't crash and I get the login screen correctly.
But after I login, the screen goes crazy. I get a bunch of
horizontal white lines appearing which make it seem like I'm
looking out a window through venetian blinds. I can make out the
icons for some of the programs that are running (Firefox etc.) but
it's effective unusable.
My video card is a GeForce GT 730. And I'm running 12-Stable on
AMD64.
Do I now need an Xorg.conf perhaps?
Does anybody have any ideas, please?
Thanks,
Graham

Following up myself...
Some time after the screen goes blank (about 10 seconds), I get a
message logged:
pid 1178 (sddm-greeter), jid 0, uid 219: exited on signal 6
(core dumped)
When I run lldb with sddm-greeter and the core file, I get the
following stack backtrace. Does that help?
In the meantime, I'll try building Qt with debug symbols.
Thanks,
Graham

Hello all,
I'm running KDE on FreeBSD 12-Stable as of last week. I rebuilt
all of my ports and now I can't get sddm to start properly. When
it starts, my display switches to vt 9 and all I see is an empty
screen. I've uninstalled, rebuilt, and reinstalled the port.
If I stop sddm and run startx, I correctly get a few xterms so I
think the X side of things is working correctly.
Below is a session from sddm.log.
Does anybody have any clues, please?
Thanks in advance for any help,
Graham
