Screensaver issue

[MR ZenWiz]

I was running Xubuntu 18.04 until a little while ago (within the last
few weeks) when I upgraded to 20.04.  I was using xscreensaver and had
to uninstall it and reinstall it for it to work.  It seems that the
new version is part of the release but I had some issues with it.

The first issue was that the xfce4-screensaver kept coming back and
taking over.  I went to Session and Startup settings to take it out,
and it came back again uninvited.  I've taken the second one out and
now it seems to be more benevolent - it's not coming back again
anymore.

However, the new xscreensaver does something I haven't seen for a long
time.  When I unlock the screen, there are a series of messages in a
tiny font in the upper left side of the screen until the unlock
completes.  they look like this (transcribed from a photo, so I hope
this is correct):

xscreensaver: unloadable, unparsable font: *-*-dina-bold-r-*-*-10-*-*-*-*-*-*-*
xscreensaver: unloadable, unparsable font: *-*-dina-bold-r-*-*-10-*-*-*-*-*-*-*
xscreensaver: unloadable, unparsable font:
*-*-dina-medium-r-*-*-10-*-*-*-*-*-*-*xscreensaver: unloadable,
unparsable font: *-*-dina-medium-r-*-*-10-*-*-*-*-*-*-*
xscreensaver: unloadable, unparsable font: *-*-dina-bold-r-*-*-10-*-*-*-*-*-*-*
xscreensaver: unloadable, unparsable font:
*-*-dina-medium-r-*-*-10-*-*-*-*-*-*-*
xscreensaver: unloadable, unparsable font:
*-*-dina-medium-r-*-*-10-*-*-*-*-*-*-*

I looked this up in Google, but the answers are greek to me and I
don't see the connection to xscreensaver.  I did try xset fp rehash,
but that doesn't solve the issue.

Does anyone know?

Thanks.

Does this help, see comment #3 in particular.

It was the first hit when I googled for
xscreensaver: unloadable, unparsable font

I've seen similar. Just uninstall it completely.

Tried installing the optional extras?

sudo apt install xubuntu-restricted-extras

sudo apt-install-xscreensaver*

Yes.  Having to reboot was annoying, but the problem is now gone.

Thanks.

I did that after I rebooted using Colin's suggestion.  After the
reboot, xfce4-screensaver came back up, so I uninstalled it (purged
it).  Now it's gone, hopefully for good.

Which is odd because I installed it with apt...

$ apt-cache pkgnames | $grep $COLOR xscreensaver 2> /dev/null
xscreensaver-gl
xscreensaver-data
xscreensaver-screensaver-bsod
xscreensaver-data-extra
xscreensaver-screensaver-dizzy
libopengl-xscreensaver-perl
xscreensaver
xscreensaver-screensaver-webcollage
xscreensaver-gl-extra

That said, it's up, no errors (I installed xfonts-75dpi and
xfonts-100dpi and renamed "dina" to "helvetica" in ~/.Xdefaults as per
Colin's reference, then rebooted).

At least it all works now.  Thanks again.

Oh, come on, man, you know better than that. *Never* ask until you've
turned it off and back on again! :-(

OK, those are the extra packages I was referring to. I don't know why
the wildcard didn't get them. I would probably try with Synaptic IIWY.
