Hi Kevin,

No problem regarding no.1 and 2 of my list because I have workarounds available
(setting in /etc/default/grub and "blind login").

But the third one (color depth) is little annoying because the "reduced color
depth" is always there, meaning also directly after a fresh reboot, not only
after resume. I tested that with that web-page (using Firefox):

http://www.lagom.nl/lcd-test/gradient.php

With the original Openchrome driver the gradient is completely smooth. With
Version 0.6.133 I clearly see two rows of 64 Bands each. Whatever that means...

This page
http://www.lagom.nl/lcd-test/display_settings.php
says I would have a color depth of 24 bit. I get the same result (24 bit) with:
xwininfo -root | grep Depth

So I have no clue where the color banding comes from.

Regarding VIA registers, I will be happy to provide you some values again. What
exactly are you interested in? All registers? Before and after resume? Also
before and after VT switching?

Best regards,
Marty
