EDIT²: Forgot about the logging again! .

Plato is running on a Kobo Aura H₂O.
The framebuffer resolution is 1080 by 1440.
Framebuffer rotation: 1 -> 3.
Framebuffer rotation: 0 -> 2.
Framebuffer rotation: 2 -> 0.
Framebuffer rotation: 3 -> 1.

I would like to avoid introducing device specific code in this module, so the 3 PUT_V are expected. My only concern is to only have one PUT_V on well behaved devices.

You caught a bug!

This has to do with the fact that resizing isn't implemented for menus yet.

I'm sorry to hear that.

I've just written the following installation instructions for Windows (I'm assuming that's what the average person uses):

Install KSM and this patch.

Download the archive for the latest release.

Connect your device to your computer.

In the left pane of the file explorer, a new item should appear under the Computer section named KOBOeReader (E:) (the drive letter might differ).

Within the file explorer, right click on the downloaded archive and select Extract All….

Specify the following path:

E:\.adds\plato

Click Extract.

Right click on KOBOeReader (E:) and select Eject.

Restart KSM: a new entry should appear on the initial screen called start plato.

Could you provide some feedback?

[NiLuJe]

@baskerville: Yeah, that's perfectly understandable (and makes sense after taking a look at the new code) .

One small nitpick on that commit's comments: the ioctl actually do "succeed" (they return 0), they just happen to not be doing anything useful .

Thank you for the instructions, even though I happen to be a Linux guy, thus actually not so average, which makes it even more frustrating that the instructions don't work. Before I try anything again (no effect thus far), I have some more questions.

I am extremely suspicious of those KoboRoot.tgz patches. I never know if they add things or remove things or both randomly. What will happen to other patches that I already applied? Will they get deleted or will they stay intact and how do I know?

And does it make a difference which version of KSM I have? I have KSM 07, I think (that's what it says sometimes when I power off).

Within the file explorer, right click on the downloaded archive and select Extract All….

Specify the following path: E:\.adds\plato

What is supposed to end up in that path? Should it be the /css /fonts etc directories and files under .adds/plato
or should it be .adds/plato/plato-VERSION directory and then /css /fonts etc?

Anyway, I have applied the patch and filled .adds/plato with /css /fonts etc with ejects and restarts as described. The result: No additions in my KSM menu.

Maybe you overlooked my response to you, in which I emphasise that you need KSM 9 with all updates, and the plato specific patch to run plato.

It is important. As tshering said, you need latest KSM (check his post).

Thing is, KSM, as koreader, plato, etc. need to know different hardware and software and they don't work in a way that they can recognize different software and hardware just like that. They need to be programmed to recognize different software and hardware.

So, go to latest KSM if you want to use Plato.

Yes, I overlooked it, because I had already followed your previous comment. I also followed the Guide in the first post, where there was no mention of the KSM version.

These details that have come up are not reducible. When they are not mentioned where they should be, such as the Guide, people will not get Plato to work.

For the time being, I will keep my KSM as it is, because it is working fine. I will try Plato again once I decide to upgrade KSM.

Plato is functional as it is, it does not need KSM and is not made for KSM. So there should not be any problem to test it without launching it from KSM.

[baskerville]

@NiLuJe: Is there a refresh mode slightly slower than NTX_WFM_MODE_A2 but capable of displaying more colors?

[NiLuJe]

@baskerville: Yep, DU.

You can also play with GC4, but it's been used much less often (as in, almost never, actually ). OTOH, I can't remember what makes GC4 so quirky. It's probably slower than DU? Might be as simple as that .

So, yeah, DU . It's actually what replaces A2 on REAGL-devices in Kindle-land. (Well, there still is an A2, but it interacts really badly with REAGL, unlike DU).

It (DU) should handle icons with alpha-blending related AA properly, for instance.

[baskerville]

@tshering: Please note that the current Plato version is 0.6.1, not 6.1.
