I got a (probably) similar bug on Dell latitude E5510 (with the same intel IGC) : external monitors works, but internal panel stay blank.
If using the Fn+F8 keys, the backlight of the internal screen ligth up, but the screen stay blank. The only (easy) way to get internal screen working is booting using failsafe mode (i.e. with nomodeset) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/946311 Title: only external screen is working with asus zenbook ux31e [eDP1] To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/946311/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
