Screenshot of how KPDF is rendering my document.

(the OS list in the bug tracker does not include Debian Jessie, however that should be the OS chosen for this bug)

I did not see this on Debian Wheezy, but I do see it on Debian Jessie. Yes, I am using TDE's Debian Jessie repo (NOT Wheezy), and I upgraded the system to Jessie BEFORE installing TDE.

My desktop does not seem to recognize that it is supposed to use KPDF for PDF files when I click on them in Konqueror; instead, it brings up a list asking me to choose an application. Choosing KPDF in the list produces the following error dialog:

TDEInit could not
launch '/home/<username>/Documents/67.pdf'.

which seems strange considering it's supposed to "launch" the document into KPDF, not launch it as an application.

I have to click the PDF document again and type kpdf into the text box provided for it to open KPDF. However, KPDF only recognizes that there is one page (there should be two), and the page is not displayed and no page preview is show (both are completely gray).

Hi Kristopher,
is this still relevant. I have been using KDPF on daily bases on debian jessie for couple of years.
The problem must be specific to your installation/distribution.

If this is still valid, let me know to debug it.

regards

This was such a long time ago I completely forgot filing this bug...

The issue as described seems fixed, though I am still experiencing the occaissional rendering issue (sometimes pages appear "black", and I need to zoom in/out to force KPDF to re-render, usually correctly). I can file a new bug report for that since it's technically different from this one, or we can keep discussions of it here.

Is it a problem to create a new account with default desktop settings and try it there.

Also what is the status of your system today?

On the screenshots it was visible that you are using some "funny" look and feel - what is this exactly now?
Stretch or jessie?
TDE 14.0.4?

I'll be away until 4.09, but we could try look into it later. I am just wondering as I was using KPDF all those years on daily bases and never had a rendering issue as described here.

I was using 3.5 and then moved to TDE 14.04. I now managed to setup build scripts and get all packages I use, so at the moment I am at 14.1 (DEV), but with all the versions KPDF never had a problem

regards

The issues as described in the bug report do not happen under new user accounts. I have not had a chance to test the "new" issue (the one with the black pages) since that one happens sporadically.

> Also what is the status of your system today?

Can you please clarify this question?

Redmond. It is a built-in "look and feel", and has been since long before TDE every existed (back in the days of KDE 3, possibly longer). If you want to see it for yourself on your own desktop, go to Control Center -> Appearance & Themes -> Theme Manager -> select Redmond -> click Apply. It certainly isn't funny for those of us that grew up with Windows 9x :-)

> Stretch or jessie?

I saw this bug on Jessie, then later CentOS 6. It seems fixed in both, though the new "black pages" issue is still there in Jessie (I haven't had time to test that one in CentOS, though I should be able to in the next week or two).

> TDE 14.0.4?

Yes.

I am stuck on old hardware and it seems that Debian and CentOS no longer care about working well on old hardware. If you can, I suggest trying this on an old machine or in a VM with intentionally limited virtual hardware that will force KPDF to render slower than normal. You will likely see at least one of the issues mentioned here. (I'm not complaining of the slower rendering speed even though KPDF used to be able to render almost instantly back in the day, only that it seems to cause issues in the way that things are rendered)

OK, clear now, I may have a look in to it after 4.09 and come back to you, if I have further questions. It is sufficient for now.

Indeed the questions were asked to try to reproduce it. I intend to do it in VM, but might be not 14.0.4. Good that you mentioned the limited hardware. Feel free to add some numbers if you like. arch i386/amd64? mem/cpu type and params etc.
As you think it is related to that.
I could even get some of the old notebooks I have in the basement, if it is easier to reproduce.

As for Redmont, I know the theme, but to me it is ugly ... and yes I know the Win95 ... actually it is more like win3 :)

regards

CPU: Pentium 4 (i686) @ 2.53GHz
RAM: 1GB
Graphics: Intel 82845G/GL[Brookdale-G]/GE with 128MB VRAM (according to lspci)

I've run KDE 3's version of KPDF on less without any speed or rendering issues:
CPU: Pentium 4 Mobile Edition (i686) at 2.4GHz
RAM: 256MB (Yes, that's MB, not GB)
Graphics: I don't remember (that laptop died years ago)

CentOS 6's 32bit is, as far as I can tell, built for i686. I'm not sure about Debian, and I can't find my spare Debian flash drive to check (I'm having hard disk troubles right now). My old KDE 3 install was built for i585.

Can't reproduce the issue and as described in comments, it does not seem to happen any more. Closing. Reopen if necessary
