The only think I can suggest is asking in the "Modifications for bad eyes thread", as tshering seems to know a lot more about this aspect of the code than I do.

Thanks a lot GeoffR, with tshering's help I was able to change the titles and the search results to normal and things are working fine for me now.

Here is what I did in case it helps others

But unfortunately the LeanAndMean screen refresh code causes ghosting problems on the older Pearl devices, noticable when using the menus, panning, and highlighting.

The LeanAndMean feature can be disabled by adding LeanAndMean=false to the [FeatureSettings] section of the configuration file, which fixes most of the ghosting problems. However this also disables the LeanAndMean touch gestures.

So for those who have disabled LeanAndMean for ghosting reasons, this patch attempts re-enable just the LeanAndMean touch gestures. (Paste into libnickel.so.1.0.0.patch):

<Patch>
patch_name = `Re-enable LeanAndMean touch gestures`
patch_enable = `yes`
replace_bytes = 6ADBA4, 7C F5 E8 EF, 01 20 01 20
</Patch>

It is hard to say if this makes much of a difference, but then I didn't notice any problems with the touchscreen response before LeanAndMean, so maybe others will feel the effects more.

Hi

I cant find [FeatureSettings] or LeanAndMean=false in the configuration file.
and the hebrew keyboard do not work.

Thanks

If there is no [FeatureSettings] section in the configuration file yet, then add it yourself. All the features have default values if they are not present, e.g. if there is no LeanAndMean feature then it defaults to LeanAndMean=true, and you need to add LeanAndMean=false to change it.

The symbols on the Hebrew and Arabic keyboards will just show as squares straight after booting the device. You will need to open a book, and perhaps open the Aa menu in the book as well, before the fonts with Arabic and Hebrew glyphs are loaded. After that the fonts should remain loaded until you next reboot.

Glo HD
Reader Settings:
Display Progress for: Current Chapter or Entire Book

Is there a way to see both in the footer? (For the epubs I have tried I can only see Entire book even with Current Chapter selected, I think I need to rename to kepub.epub)

In the <-> (page scroll popup) it lets you jump to chapters (<< and >>) so there must be a way to figure out how many pages are left in the current chapter?

I'd like to see both in the footer. Any solutions?

Thank you GeoffR

Geoffr, do you know how to create a patch for disabling auto page refresh after panning in Aura h20.
It it is not possible, is there any way to disable auto page fresh in kobo completelty

Thanks in Advance.

The per-chapter page numbers only work with kepubs (and only if the kepub is properly split into one-file-per-chapter.)

If I had access to the source code I am sure I could add this feature for epubs in ten minutes, as the Adobe page number calculation is very simple (compressed size of current file / 1024), but doing it via a patch would probably be very difficult.

It might be possible to do this, I'll have a look.

Would it be possible to add a disable pinch to change font size on epubs for this version? The check box isn't working in this version(bug)

Thanks

How did you enable this in the first place? The Glo doesn't support it at all. It is there for the Glo HD and, I think, the Aura. On the Glo HD, the pinch is used in PDF and images to allow zooming. For the Aura, it is for font resizing.

If this is a for a Glo, have you installed the multi-touch kernel in the past? If so, you need to install the kernel from the current firmware update package.

OK, in that case, I don't know why the option isn't working.

Yeah me either, other people in 3.15.0 discussion thread say they are having the same problem. Its disabled for kobos kepubs but not for normal epubs..so weird.
auraborealis posted a patch for 3.3.1 to disable it for epubs here; https://www.mobileread.com/forums/sho...&postcount=162

I was hoping there was one for 3.15 as well.

EDIT;
For now I downgraded to 3.13.1 and the bug isn't in that version, plus it seems faster to me anyways.

Question; is it possible to remove the header and footers and the side margins completely, so there is no blank boarder area at all? If so, what patch settings should I use?

[rogerinnyc]

Quick question for those more knowledgeable than myself: is there anyway with patching or editing internal files to customize the font menu on the Kobo H20 so that it ONLY lists the fonts I want? I know Geoff's patch allows you to get rid of a bunch, but toggling that on eliminates the possibility of add-on fonts -- plus I wouldn't mind getting rid of some of the standard font choices too.

Thanks in advance for any insight (or even a "it's not possible at the moment")

How about the full page setting...
By editing the file .kobo/Kobo/Kobo eReader.conf
Enter the next line under : [FeatureSettings]
FullScreenReading=true
After this a new menu entry in the Reading page of the Settings is available, called Page layout, where one can show/hide the header/footer.

I do have that setting enabled..but there is still a slight boarder of white space all around..seems pointless making a device with a 6 inch screen and only 5 inches is really used for displaying text... Oh well I guess I'll just have to live with it.

Be very sure that is not in the .css of the book, if they have top,left,right and bottom marges set,you can't change it in the reader.
You can use patches to adjust them but if u have a book without the marges,it isn't always centered.
Look at the code in the .css of a random book I opened, with that code,you will never use the full screen so u have to remove that part out of the book.

@page { 
   margin-left: 1em; 
   margin-right: 1em;
	margin-top: 1em;
	margin-bottom: 1em;
}
