Hi Kevin,
With the new Version 0.6.133 of the OpenChrome driver (from git repository) I
see color steps in images. This is not related to resume/standby because it is
also there after a complete reboot of the computer.
I tested that in more detail with that web-page (using Firefox):
<a href="http://www.lagom.nl/lcd-test/gradient.php">http://www.lagom.nl/lcd-test/gradient.php</a>
With the original OpenChrome driver of lubuntu 14.04 the gradient is completely
smooth. With Version 0.6.133 I clearly see two rows of 64 bands each.
This page
<a href="http://www.lagom.nl/lcd-test/display_settings.php">http://www.lagom.nl/lcd-test/display_settings.php</a>
says I would have a color depth of 24 bit. I get the same result (24 bit) with:
xwininfo -root | grep Depth
My system:
Fujitsu Siemens Amilo Li 1705
VIA VN896 chipset
lubuntu 14.04 (upgraded to 14.04.5, but I didn't use a point release, so it is
not a HWE version)
OpenChrome V0.6.133
Best regards,
Marty</pre>
