Can you guys play against the computer on chess.com? Looks like my jre is not working here. I'm running Linux Mint Isadora XFCE4. Is there a workaround for this?

Yes, the work around is 'sun-java6-jre'

Also make sure Java is not disabled in Firefox.

you should also make sure that the iced tea plugin is disabled, but I don't believe Mint enables it by default (though it is in the repos).

Thanks for your hints! 

Yes, the problem was java-6-openjdk. Don't know why it was there, anyhow I tried to make java-6-sun the default alternative through the Alternatives Configurator, to no avail. So I removed java-6-openjdk and now all works well. I guess that's a bit rough though.

I'm having the same problem myself. I've seen that if I uninstall openjdk a lot of programs that I use will be removed as well. What can I do?

Not sure. I have...

openjdk-6-jdk
openjdk-6-jre
openjdk-6-jre-headless
openjdk-6-jre-lib
sun-java6-bin
sun-java6-javadb
sun-java6-jdk
sun-java6-jre

as well as

icedtea-6-jre-cacao
libcommons-lang-java
libcommons-launcher-java
libnb-javaparser-java

And it works fine. See if your missing one.

I was missing some of those files, but I've already installed them all, restarted Firefox and still no deal. Not working on Chromium either.

Which dist? and have you updated or is this a new install?

My distro is Ubuntu 10.10 and its up-to-date.

I'll try it over the weekend and let you know what I find out.

Thank you very much for your help, nulesus!

Desktop edition 32-bit version right?

Exactly.

Ok after some testing with a fresh install. Get rid of the openjdk complete removal.
And restart your user session.

I also tested Linuxmint 10 which works well with Sun-Java6 right out of the box. (at least the DVD version) I did not test the non-free or the CD install.

Every year I end up trying out Ubuntu and end up with Linuxmint. However Ubuntu seems well suited for the dedicated xbmc box. (Intel or PPC)

It's working, thank you very much for your help, nulesus!

I'm running Kubuntu 10.04, 64-bit.  I found this old forum thread and started piddling around following the ideas in this thread, but I've experienced no joy.

Is the "play against computer" thing even any good?  If its engine is as stupid as the one in Computer Workout, maybe I should be glad to just walk away and forget about it.

It would be nice to be able to use the "finish this game against the computer" feature though.

Fscking Linux.  I hate it.  I just hate Windows even more.

what distro you have?
