Full refresh before displaying screensaver
Hi, All,
does anybody know how to do full screen refresh before displaying screensaver image? When I put my Kobo to sleep, i have last reading page drawing on top of screensaver image (instead of just black color) Also what is the automatic sleep timeout? Did not find it in any settings.. |

The automatic timeout is set to 60 minutes by default, and I don't think it's available to set anywhere in the UI. I don't even rightly recall how you can customize it OTOH.
On which device is that? And which KOReader version? And in which ScreenSavers mode? I killed an extra useless refresh in the nightlies a few days ago, but the ScreenSaver itself should still flash, which should prevent much of the potential for ghosting, at least on most devices. (The best way to actually handle this would be a flash to a white screen *before* showing the ScreenSaver. Recent Nickel versions opt to show the ScreenSaver without a flash, then flash on top of that, which works okay, but may introduce a few artefacts). I'm going to take a wild guess and say this is an Aura? |

My "settings.reader.lua" has this added to it " ["auto_suspend_timeout_seconds"] = 480," and works fine for an 8 min timeout.
(I thought it was once in the screensaver settings menu, it's not there now.) Luck; Ken |

@Hamsky: That doesn't answer my "which version of KOReader" question .
Doing the white-screen trick would mean code changes. I'd go with a new framebuffer method that just does a full memset to 0 to bypass any blitting, and stick a refreshFull after that. And time all that before the ScreenSaver repaint. And only do that on full-screen ScreenSaver modes. Last edited by NiLuJe; 02-13-2019 at 10:34 AM. |

I update my Kobos every month, so now my version is 2019.02.
