force the E-ink screen to refresh??
I'm working on a kindle info display app, however I'm having trouble with screen afterimage on the kindle when the text is updated. Is there any com.lab126 or Linux command that will force the E-ink screen to refresh?

It's bundled with USBNet (and, well, itself ;p).

When I wrote my post, I didn't have access to my kindle with heavy ghosting. I tried it this morning and eips '' had no effect, nor did fbink -s
When I ran fbink -f -s it worked perfectly. Maybe some firmware version and model combinations need an extra shove. |

You do need `-f` to request a flash (everywhere) .
Otherwise, the default waveform mode (and every mode that's not a `GCn`, for that matter) will not even touch pixels that haven't changed since the last refresh. |

That's because it doesn't say that outright . It's already a giant wall of text, so it's assuming the reader has a basic understanding of the technicalities involved in stuff that isn't directly related to the behavior of the CLI itself and/or of FBInk itself.
The API doc, on the other hand, delves into the guts of things (e.g., this would be the relevant bit, as well as the bit about AUTO that explains that flash + AUTO means GC16 in FBInk. There are even more details about that particular design choice in the code .)). When in doubt, check the API doc, it's much more detailed, and much better contextualized .
