I have also upgraded my bios to version 504 and indeed it is not helping but there is a change in the fact that the back-light is now turning on allowing to see video artifacts.
I've succeeded to get something on screen by using 'nomodeset' kernel parameter but at the end the X session is running in some sort of low resolution (VESA?) Maybe this would be resolved by usage of some proprietary driver but there is no "Additional Drivers" available from UI. And proprietary was not needed in the past. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1446504 Title: Asus X200MA Black Screen after LTS Update (3.13.0-49-generic) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1446504/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
