Thanks for the report... I couldn't understand why it didn't work. anonimo200, it should work everywhere, not just in the PDF reader.

A single contrast change is often subtle, and if there aren't many shades of gray the screen won't even flash. To be sure it's working, push Shift + click the fiveway and it will invert. Also Shift + left twice will go to monochrome mode, which should be obvious e.g. in the status bar at the top of the screen. After that it would also stop flashing between updates.

Glad you got it working! Unfortunately I can't help directly with those PDF viewer features. Your options would be to do one of the following:

Is there any good reason this isnt packaged up for the k2 + k2i, AFAIK they are an indentical FW...

is the Left shift on a k2i

[root@kindle root]# pidof contrast

K2i repack.

Works fine.

Same keys.

And incidentally... I had to reboot "again" to get this one activated too... Just like the 1st time on the DX. Still dont know why.

For those that missed it:

echo "99 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0" >/proc/eink_fb/update_display;
echo "18 0" >/proc/eink_fb/update_display


to invert screen. awesome on a k2i

Or push Shift + fiveway, hopefully (if the key watcher is working on K2 anyway).

tested this on another virgin k2i

it definitely needs a "Restart" after the installer has finished to pick up the changes.
Still not sure why.

SHIFT + 5WAY UP (few times)
SHIFT + 5WAY LEFT (few times)
SHIFT + 5WAY PUSH (this give the optional colour inversion)

gives white on black no flashing updates and a k2i.

Tasty

It should always start up with the default contrast (if you actually turn the Kindle off, not just put it to sleep). You could also use the arrows to set it back to the middle level and max shades of gray. But uninstall worked too, last I tried it.

I have Kindle DX white (b004) 2.5.8, and your upgrade doesn't work on it. The "Update" menu item is greyed out.
Where can I find your update for contrast and other enhancements for Kindle DX White?
