Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I've posted about this before and I can't believe I'm the only person seeing this : xpdf is slow to render PDFs and navigating through a document is ponderous. The problem is there on my laptop ( Core i3 ) and my desktop ( Core i7 ). I played with the ./configure options in the Slackbuild and deleting the -mtune=i686 option made it much more responsive. I'm not smart enough to debug the problem myself so any help would be appreciated. It's so bad I've got Debian on a separate partition and I boot into that if I need to look at PDFs.
same here. i have researched around and didn't find anything that fixed it for me (i remember someone talking about the font configuraion, somewhere on this forum). i just gave up and am using epdfviewer, evince and okular... i would be very interested in the solution tho!
Ahh, that would shed some light on this... I have Windows fonts installed in my .fonts so perhaps xpdf has less of an issue rendering documents for me. Interesting to hear if the OP has Windows fonts or not...
13.37 on an i3 here, and the same thing; loads up fine but scrolling sucks real bad. I initially ignored it and started using okular instead, but I am going to try the modified xpdf.rc from linked thread.
I read something in the past about GCC changes with regard to floating-point calculations causing some trouble. If I remember right, the code checks some floating-point numbers for equality (no tolerance), and the GCC changes break xpdf's caching because the comparison doesn't work as it used to.
i've had this problem on slack13.1, back then it was the float-issue. i recompiled it using a patch and everything worked -- unfortunately, this was quite some time ago and meanwhile I have switched to a 64-bit machine, so I don't know where i got it from any more .
but a quick google found this one: http://recipes.gobolinux.org/r/?list...03-float.patch
maybe you could give it a try.
I prepared simple chart using LibreOffice Draw module and exported it to PDF file. When I open it with Xpdf and I try to scroll the chart horizontally, vertically or diagonally using my ThinkPad’s TrackPoint top reports Xpdf uses 97–100% of CPU and the chart rewinds very slowly.
