That seemed to fix it !

Thank you. Mupdf displays the documents OK, and I'll probably rely on it
until the ASCII upgrade becomes stable. I gather its version of
libpoppler does not have the bug.

Nevermind! Forget what I wrote - I mistakenly tested with ASCII instead of 
Jessie, sorry! 

Adam Sampson was spot on: On Jessie, downgrading libpoppler46 to 
0.26.5-2+deb8u1 
allows to get around the bug that is perfectly reproducible with ...+deb8u3.

Hi Adam,

interesting! FWIW, on Devuan ASCII libpoppler64 0.48.0-2+deb9u2 works fine,
even with the test document provided in #890826.

Hi Haines, hi Ron,

just a random shot in the dark, but since AFAICT atril and xpdf do not 
share the same rendering engine (going solely by package dependencies, 
I might well be wrong on that account), this could possibly be a font 
caching problem. Maybe a forced rebuild of the font cache might help: 

  fc-cache -rf

FWIW, I can not reproduce any obvious rendering glitches here using any 
PDF software based on the usual libraries (cairo, pango, poppler, ...),
and I have a metric to of fonts installed on this here system. (While 
typing this I remembered years ago I had problems due to a broken font 
file, but that did not result in a _total_ loss of PDF font rendering 
capabilities across different tools.)

BTW mupdf would be yet another simple viewer for you to try, in case you 
haven't already.

HTH, best regards
Urban

Hallo John,

not having had this problem myself, but following this list and
#devuan, I suppose, that you have some leftover udev -> eudev
initscript and/or symlinks in your inittab.

I'm seeing the same problem on plain Debian with xpdf and evince -- it's
one of several problems that were introduced as part of security fixes
in libpoppler46 0.26.5-2+deb8u2. ...+deb8u1 works OK, if you don't need
the security fixes.

There are a couple of Debian bugs about this already:

Hi John,

IIRC this is a known problem during updates that is about to be fixed 
before ASCII goes stable.

Please try to:
  1. remove the transitional udev package (if applicable)
  2. move the file /etc/init.d/udev out of the way (if present)
  3. reinstall (or rather configure) the eudev package.

I have noticed the same behaviour in recent days, but while the .pdf files do 
not display properly in evince or pdfshuffler, they do in gv.

[DNG] broken PDF display

[Haines Brown]

Recently and not in association with any system changes, atril and xpdf
no longer displays the content of perhaps half my PDF files. They see
all the pages, but they are blank. An exception is that sometimes a
cover page, TOC, download notice at bottom of pages, or the graphics are
displayed, but not the text. This is consistent: a failure or success
repeats on subsequent tries.

This happens whether the PDF is version 1.4, 1.5, and 1.6.  It happens
on my desktop machine whether using atril or xpdf. It does not happen if
I copy a problematic PDF to USB key and display it with xpdf on a laptop
that has the same version of Devuan Jessie, kernel and xpdf. However,
that same file on key fails to be displayed by my desktop machine.

The desktop has auto-upgrades, but not the laptop. However both machines
running Devuan Jessie with 3.16.0-4-amd64, The version of xpdf the same
on both desktop and laptop. 

I've got 32 Gb RAM on this machine and no other PDFs are being
displayed. I tried to reboot to clean things out, but that didn't help.

The xpdf Find utility can find words in the body of a text, but displays
them only as black rectangle. So the problem seems to be the display of
the font.

$ xpdf -fg black Abrams1995.pdf
error: "black" file not found

Printing the PDF has same result as its display.

[DNG] Dist-upgrade to ACSII error

[John Crisp]

Oooops.

Was upgrading to ACSII and all was going swimmingly until right near the
end (usual Friday then !)

Seems eudev is in a knot.

I think it probably needs removing and reinstalling, but that wants to
rip out all the kernels !!!

Any suggestions on getting out of this one without a reboot?

I think that may be where some of my issues lie - I am going to uppgrade
to ACSII and then look again

Oddly despite my dnsmasq having /var/run/dnsmasq/dnsmasq.pid the file is
actually created as /var/run/dnsmasq.pid

Something odd there !

I'll go upgrade and take another look.

Thanks again.

[DNG] maxima/wxmaxiam in ascii

[Dr. Nikolaus Klepp]

I have an interesting problem with maxima/wxmaxima on ascii:

wxmaxima and maxima can solve this equation:

solve([x²+y²=r², (x-a)²+(y)²=p²],[x,y]);

but this equation is solved in maxima, but not in wxmaxima (gives an empty 
solution):

solve([x²+y²=r², (x-a)²+(y-b)²=p²],[x,y]);

Could somebody please try to replicate this result?
