KOReader: Disable HW inversion in case it's unreliable (e.g., mxcfb on old ntx kernels).
Raw
2-disable-hw-invert.lua
local Device = require("device")
local Screen = Device.screen
-- Flipping canHWInvert affects what fb:toggleNightmode does, so make sure we flip it with NM *off*,
-- because it'll already have been run by Device:init before this patch runs...
-- Otherwise we'll flip the Screen's bb invert flag the wrong way around ;).
local is_nm = Screen.night_mode
if is_nm then
Screen:toggleNightMode()
end
Device.canHWInvert = function() return false end
if is_nm then
Screen:toggleNightMode()
