]]> Issue:

Starting Chrome in Windows 7 guest from Virtualbox happens to see only flicking windows with flashing rate around 2-4 rounds per sec.

Solution:

Turn off hardware acceleration in Chrome setting or uncheck 3D acceleration in Virtualbox.

Tricks:

When flicking occurs, you cannot start Chrome, thus no way to turn off hardware acceleration at setting. Either start Windows in safe mode, then start Chrome and change setting or shutdown windows then uncheck 3D acceleration setting in Virtualbox, and start windows again.

Config:

  • Chrome 47.0.2526.80 m (64-bit) for Windows
  • Windows 7 Service Pack 1
  • Virtualbox  5.0.10

]]> Issue:

After installing Fotorama plugin in Piwigo provided that there is Embedded Video installed, the following error message will be shown while clicking the slideshow button on top of the video pages: Notice: Undefined index: selected_derivative in /…/plugins/Fotorama/main.inc.php on line 54 Fatal error: Call to a member function get_type() on a non-object in /…/plugins/Fotorama/main.inc.php on line 54

Solution:

Maybe it is just a workaround for the issue. However, it works so far. Comment out the statements causing the error in main.inc.php of Fotorama plugin as below:

$type = $current[‘selected_derivative’]->get_type();
    $defined = ImageStdParams::get_defined_type_map();
    if (!isset($defined[$type]))
    {
      $type = pwg_get_session_var(‘picture_deriv’, $conf[‘derivative_default_size’]);
    }
and rewrite the following line:
$type = pwg_get_session_var(‘picture_deriv’, $conf[‘derivative_default_size’]);



Config:

  • Piwigo          2.6.2
  • Embedded plugin: 2.6.2
  • Fotorama plugin:   2.6.h
