asgard2, ok. So to start from the beginning, in Precise if you use Bumblebee, it's not supported by Ubuntu, as it's not in the Precise repository, but a PPA.
With this in mind, your Precise lspci showed your nvidia card wasn't even working, and everything seemed to be flowing through your Intel card (probably due to Bumblebee not working right or you had nvidia card disabled in BIOS). Despite that, just to clarify on your Saucy test, all you did was have both graphics cards enabled in BIOS, no Bumblebee, and was relying on only nouveau, correct? As well, if you install the nvidia drivers only in Saucy (no Bumblebee) does your HDMI work for you? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040053 Title: [Dell XPS 15 L502X] no HDMI support with dual grafic card in Ubuntu 12.04LTS with 3.2.0-29-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1040053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
