okular not working

[blobfish]

don't know if I need it. I never installed it.

I'm seeing this with one trusty machine but not on another with the same pdf.

I don't think the XRandr debug message is relevant, though, as I get that even with the machine that shows the pdf correctly.

One thing I noticed is that when I choose File>Properties in okular after opening the file, the machine that does not show the pdf reports paper size as nan x nan, and the one that works reports paper size as A4...show this could be a problem with locale paper settings.

I haven't figured out the delta between the two machines yet (I'll probably get a diff of installed packages and locale settings later).

I was thinking that while retiring for the evening.

I noticed something similar. I am getting "0 x 0 in (unknown portrait paper size)" in the status bar.

Check your Local settings.

I have exacly the same problem. Any progress?

Any progress?

Unfortunately not, haven't yet found a diff on my two machines that would explain why one works and the other doesn't (I'll keep my eyes open, though, and report here if I spot it).

A couple of things:

1.Check /etc/papersize . In the US it should have one word - letter . I guess elsewhere it should be A4 .

2. Can you open your pdf files with something else such as evince, xpdf, ghostview, gimp, libreoffice, etc?

3. Check your pdf files with pdfinfo and see what paper size it is reporting.

Trying to determine whether this is a okular problem or a more general problem with how the system is handling pdf files. Works fine here.

Yes, I have done all these...and the some

1. /etc/papersize is correct and same on both machines (the one that works and the one that doesn't), although I'm under the impression kde software doesn't check /etc/papersize (because kde has the locale setting for papersize)
2. xpdf shows the pdf fine, so does print preview in okular.
3. pdfinfo checks out as well.

Other things I've checked:
4. On the machine that doesn't show the pdf, the "bug" is also present with a new user (so should not be a problem with user settings)
5. Tried with other pdfs, same results (so not a problem with a particular file)
6. The delta between the packages installed on both machines is very small (and nothing that *should* be relevant)

No useful console messages either, although I haven't yet tried with all debug messages enabled (I'll probably do that once I get the chance)

Just wild guesses at this point, but:

When okular hangs are you going to 100% on some process? Check with htop or the CTL-ESC system monitor running while you run okular.

Edit: Might also check /var/log/Xorg.0.log for any errors.

Okular doesn't hang, it just won't show the pages...I can view the print preview (which shows fine) and check the file properties etc. It works in every way...except the not showing the pdf pages part . Processes behave themselves.

Edit: Might also check /var/log/Xorg.0.log for any errors.

You probably mean ~/.xsession-errors (although trusty actually logs session errors to ~/.cache/upstart/*.logs...and yes nothing that would explain this there either)
/var/log/Xorg.0.log logs Xserver startup, not the errors from user's Xsession.

Anyway, thanks for all the suggestions, at this point I'll welcome any suggestions (even the outside-the-box ones)...I'm not really in a hurry to solve this, as I can access pdfs on other machines or with other software...but the issue is really mind-boggling...which is of course part of the fun .

Nice find Rog, that would explain it, my trusty machines have different graphics cards/drivers, so that would explain the difference between the two.

It should be fixed in 4.13 then, and I can stop scratching my head and find something else to waste my time with...pub, here I come

Confirming issue fixed in KDE SC 4.13 (final)
