The way to get around that is to manually copy
/pluginssubdirectory under Opera's root directory. ( Thanks to the guy in #opera@freenode who told me to look under
Tools |Preferences | Advanced tab | Content | plug-in options |to find out where to stick
It's not too difficult to install the flash plugin, just download it, untar the archive, copy
libflashplayer.sointo the subdirectory and you're done!
While Flash works, it does not seem like it's working completely yet. On my console, I've noticed a couple of error messages like the ones below, which seems to suggest that the plugin isn't working as intended:
(process:27461): GLib-GObject-CRITICAL **: gtype.c:2254: initialization assertion failed, use IA__g_type_init() prior to this functionOn sites like YouTube and Yahoo Finance, Flash seems to work properly, even with the error messages shown, but on kongregate.com, most of the Flash game widgets will not load, where the only output is only a grey box, indicating that the plugin isn't running.
(process:27461): Gtk-CRITICAL **: gtk_clipboard_get_for_display: assertion `GDK_IS_DISPLAY (display)' failed
Adobe FlashPlayer: gtk_clipboard_get(GDK_SELECTION_PRIMARY); failed. Trying to call gtk_init(0,0);
opera: Plug-in 27461 is not responding. It will be closed.
opera: Define environment variable OPERA_KEEP_BLOCKED_PLUGIN to keep blocked plug-ins.
Other times, visiting sites with flash content on Opera will cause a 90% CPU utilization, the culprit being
'operapluginwrap'. This seems to affect other plugins as well.
Opera 9.50 is still an Alpha version, so I'll give it a benefit of a doubt. Hopefully these issues can be resolved in the Beta stage, and definitely I won't want to see this in a 'release-candidate'. Hope that the issue will be fixed soon!
