Anyway, I am a 64 bit user and have had no issues with anything apart from flash.
I have tried the 32 bit plugin with ndiswrapper which was awful and very slow to respond. I have also tried several open source alternatives such as Gnash and although they are coming along well they don't seem to be up to much as of yet.
A while ago Adobe released a 64 bit plugin but it was scrapped and removed from their site due to an apparent security hole.
However it is now back and apparently fixed so I have tried it and it works reasonably well.
It has been nicknamed "Square" and is availible for Windows, Mac and Linux.
The only noticable difference is that flash videos are no longer stored in /tmp/ while streaming but are now in your browser's cache, for firefox users this would be /home/user/.mozilla/firefox/profile.default/Cache/ .
For Ubuntu users there is a PPA for it. To install use:
bash$ sudo add-apt-repository ppa:sevenmachines/flash
bash$ sudo apt-get update && sudo apt-get install flashplugin64-installer
For other distro's or for those who want it directly from adobe labs the download link is:
Installation of the Flash preview has to be done manually – but this isn’t that difficult.
Unpackage the file.
Copy the libflashplayer.so file to the plugins folder of your browser:
I hope that works for 64 bit users out there. Its certainly much smoother for me.
Users should note that as this release is termed a ‘preview’ and should not be taken as a final stable release so may be slightly buggy.
