[Bug 1304627] Re: Can't enable third screen on Samsung NP700Z5C
I have the same error on my laptop, running 14.04 LTS with an AMD Radeon Mobility HD 5800 series graphics card. I attempted to plug in a monitor into the HDMI and one into the VGA ports, while running the laptop screen. From researching, it appears that this card, and presumably others, only allow two legacy connections , and I'm assuming that one of those connections is taken up by the laptop monitor, preventing the third monitor from being activated - if I activate the HDMI monitor, the VGA switches off, and vice versa, again with the unintelligible error messages observed above (I think mine said CRTC 148/149, and same unmapped Quark error. If your graphics card has a DisplayPort, you can use an 'active' adapter and plug in the third monitor, as one solution. Hopefully this description can help run down the string error msg, and at least this description might help someone who arrives here by Google. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1304627 Title: Can't enable third screen on Samsung NP700Z5C To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-control-center/+bug/1304627/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I see nearly the exact problem on Dell XPS 15, which is Intel+Nvidia GeForce GT 630M, should be similar to the Samsung's Intel+GEforce 640M. I have the Nvidia driver working, both outputs work, but not at the same time.
