quixote_arg, unfortunately as you are using the upstream drivers, you would want to seek support from nvidia directly. The nvidia drivers that are supported in Ubuntu are those only from the Ubuntu repositories as noted in: https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia#NVIDIA_drivers_provided_by_the_Ubuntu_repositories
If you can reproduce via either nouveau, or nvidia drivers from the Ubuntu repositories, please file a new report with those drivers installed specifically via a terminal: ubuntu-bug linux ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1239348 Title: ubuntu 13.04 suspend fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1239348/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
