sorry for my late answer I updated Saucy to kernel 3.11.0.7, if I try to activate the HDMI I recieve: xrandr: Configure crtc 3 failed.
and the second screen is detected at HDMI-2 now. It is completely not working anymore with nouveau. Do you mean a new bug for nvidia-current problem with nvidia-detect "none"? -- 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
