I have a Toshiba L505D-S5983 laptop with the Athlon II X2 and the Insyde H2O bios. With 9.10 only one core is recognized. As far as I can tell the bios is the latest. I tried changing all the things the other posters indicated with no change. Here is /proc/cpuinfo:

This is what others reported for this laptop and Ubuntu 9.10. -- Athlon X2 not recognized as dual core https://bugs.launchpad.net/bugs/437821 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
