I have a new Macbook Air 2012 Model and it seems that I have the same problem as reported here.
An older kernel version 3.3 works fine, where as newer ones give me a black screen. Daniel asked me to test the latest patch from here. I applied "Check combined VBT/register delay" on top of todays drm-intel-next (20d5a540 drm/i915: don't grab dev->struct_mutex for userspace forcewak). Eventually the screen is black again. But there is a small difference: before it turns black I see kernel boot message (booted without the 'quiet' argument). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
