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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1446504 Title: Asus X200MA Black Screen after LTS Update (3.13.0-49-generic) Status in linux package in Ubuntu: Incomplete Bug description: related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1427646 Description: Ubuntu 14.04.2 LTS Release: 14.04 cat /proc/version_signature := Ubuntu 3.13.0-49.83-generic 3.13.11-ckt17 Linux Lux1-Ops-LiloXX 3.13.0-49-generic #83-Ubuntu SMP Fri Apr 10 20:11:33 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-49-generic 3.13.0-49.83 ProcVersionSignature: Ubuntu 3.13.0-49.83-generic 3.13.11-ckt17 Uname: Linux 3.13.0-49-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.10 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/by-path', '/dev/snd/controlC0', '/dev/snd/hwC0D0', '/dev/snd/hwC0D2', '/dev/snd/pcmC0D0c', '/dev/snd/pcmC0D0p', '/dev/snd/pcmC0D3p', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: Date: Tue Apr 21 09:45:44 2015 HibernationDevice: RESUME=UUID=8cfe631b-97f1-4da1-b1b2-15675c32779e InstallationDate: Installed on 2015-01-19 (91 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.2) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 05e3:0608 Genesys Logic, Inc.
