In landscape view KOreader crashes every few pages and the reader reboots. Suspend / power button don't work. Every other thing seems to work (light button, PDF with different zoom modes, epub, file browser). USB-connection don't work (should it?), pressing on home button in file browser the reader reboots (is that the normal way to kill KOreader?). Last edited by blablub; 09-08-2013 at 05:46 PM. |

Yes, the File Manager home icon in the menu, is how you reboot back to Nickel. Luck; Ken |

Adding fonts to koreader
I am trying to add fonts to koreader by copying them to the directory koreader/fonts
Some work, some don't. Some fonts are not recognized by their filename, but by their 'family' name. For example the beautiful font Brioso. So if I put more files into the folder of the same font family, I only see one name. How can I do this properly? |

Odd that it seems to be the PDF side of things that is having the most problems now, after all the project started with PDF in mind.
Not likely a hardware issue. "Segmentation fault" = program error, the program is trying to access something that it isn't allowed to or doesn't exist. On very rare occasions a hardware issue could make something the program is trying to access unavailable in a way that could cause a segfault. "Nightly Builds" are traditionally very much a matter of software under construction, they allow all concerned, especially those working on the project, to see how the recent changes/additions effect the overall status of the program. They are in no way meant as a finished program. We are just lucky to be far enough along in the project development that, for some of us at least, the builds provide a mostly working program. Don't despair, they will get there and we get to play with their work along the way. The hope is that our fumbling with the nightlys will expose the nature of problems that the team are dealing with.

Luck; Ken I just put it in /fonts/freefont/ and it seems to be working in the current .epub I'm reading. I had to find the Change Font in the top menu, I kept looking for it in the bottom one. This font is very simple and it appears to ignore things that were creating artifacts in the text, making it easier to read. Last edited by Ken Maltby; 09-09-2013 at 01:54 PM. |

Same landscape bug (crash) even with CBZ and not only PDF.
Furthermore big cbz (like 300MB) need much time to be opened (the first time). Time like 60 or more seconds, in this case will be useful a message in file manager like "loading please wait". With so long waiting pause, without a message is difficult to understand if we must only wait or if the click has not been got by touchscreen (and we are waiting for nothing, no file has been selected). I have noticed also (with CBZ and PDF) that margin set to medium and large corresponds to the same screen rendering, only margin small changes the screen. Is it correct or is it another bug (medium icon set large preset instead medium) ? Last edited by Fabry; 09-10-2013 at 05:49 AM. |

Even Crop mode setted to Auto seems to do nothings (big white borders always present with all page margin mode).
I must change to SemiAuto and then revert to Auto to see Auto works for really. Sometime touchscreen stops to respond (more often with cbz but also with pdf) and koreader seems freezed. Sometime it will recover after many seconds (often more than a minute) during which I continue to touch various screen areas, trying to recover koreader usage. In this case I have found out a trick to solve. By sliding the power button when koreader seems frozen, reset the problem and touchscreen will immediately be used again Last edited by Fabry; 09-10-2013 at 05:51 AM. |

Fabry: That margin thing might be a bug, but I'm not sure how it is supposed to work for the document you tried it with. I'm not so sure why it takes *that* long to open a CBZ - will need to try it myself.
Auto-Cropping will probably only work with PDFs, maybe others when reflow is used. We still need to do a lot of debugging and bug-fixing. Koreader is still in an early stage - where it works fine for some things, not so for others. |

Markismus: I'm not really sure about the state of things with multi-master fonts and/or OpenType fonts with multiple faces included. While freetype does in principle support them, I think that neither KoReader nor the rendering engine we use (crengine) really has support right now.

And reading 300MB needs many seconds (often more than a minute). If I reopen it (after reading other documents) it opens quickly enough (less than 5 seconds, often less than 3), something cached ? This cache seems to survive to koreader reboot, only newer cbz file will be very long to open. Quote:
If I open a new pdf (never read before) crop is to auto-crop as default but no changes happen when I change margin setting to small. Always big white border around. But if I switch to semi-auto (setting a manual border and then confirming) and then I revert to auto it seems that now also auto-cropping is working (at least it responds to margin changing). Quote:

Of course, and feedback is highly welcome. Reading CBZ should be faster. It's a ZIP and has a table of contents - lookup of individual files should be fast. Auto-cropping PDFs depends on the content type (in non-reflowed mode) - it looks for a rectangle actually covered by content. In the worst case, this contents might be white bars. Also, scanned PDFs cannot be automatically cropped this way if the white margins are part of the actual bitmap (the scanned image) laid out on the PDF page. I'll have a look and will try to reproduce. In any case, thanks for each and every bug report!

Tinkering with the koreader_kobo.sh script
After numerous crashes and an altogether laggy experience of koreader I remembered the extra lines cgm999 put in his koreader_kobo.sh script, which is situated in the main koreader directory.
The result is as of yet astounding:
The changes to koreader_kobo.sh the following added lines: # Decrease the reasons for crashes. Search forum for cgm999's explanation. exec 3<&- # Stop nickel and related processes killall nickel killall adobehost killall dbus-daemon killall hindenburg Just copy-paste those lines after the first line (#!/bin.sh) and before the call to reader (# finally call reader).
