Earlier, Google rolled out an update which added Linux support for Google Talk’s Voice and Video chat. Unfortunately, the update has been packaged only a debian deb file. Fortunately, Jigish Gohil, more popularly known as “CyberOrg” in the openSUSE community has a solution.
The debian package is a archive consisting of the required libraries and a cron job, Jigish has extracted the files and rolled it into a tarball. To install, just download the tarball and extract it to the root folder. To do so, open the Terminal.
Switch to the root user:
su root
Next, use tar to extract and move the files
tar jxvf /path/to/downloaded/file/google-talkplugin.tar.bz2 -C /
Replace /path/to/downloaded/file with the location at which you downloaded the file. Restart your browsers, and you should be ready to start talking!
Update:
Google now provides an RPM package, just head over to the Download page and select the required file.
