Thanks for your follow up Christopher $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date X200MA.504 11/13/2014
The advanced side of LP#1416849 is that the identification of the kernel working and new not working is done there. (thanks to exercises made on kernel-fixed-upstream tags side) I'm not sure why you want to work on 3 bugs thread for same issue? And also I don't understand why you don't confirm that bug? There is indeed more that one person affected isn't? Installing a fresh image of a LTS 14.04.2 is installing 3.16 kernel base and that "LTS 14.04.2 3.16" is working. no black/white screen issue. The laptop having issue reported in this thread (and other thread) are installed from LTS 14.04.2 having kernel (point release? ) stuck to 3.13 doing an apt-get update & disp-upgrade don't update that laptop from 3.13 to 3.16. I believe the solution for my issue is to found the best way to upgrade my laptop(s) from 3.13 to 3.16 while staying on a real LTS 14.02.x release. doing: sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic from https://wiki.ubuntu.com/Kernel/LTSEnablementStack resolve the situation since it move to GNU/Linux Description: Ubuntu 14.04.2 LTS Release: 14.04 Codename: trusty Linux Lux1-Ops-LiloXX 3.16.0-36-generic #48~14.04.1-Ubuntu SMP Wed Apr 15 13:11:28 UTC 2015 x86_64 x86_64 x86_64 But I'm not sure it is what I want/ the best option. So, so far for me, Ubuntu 14.04.2 LTS installed prior to 3.13.0-44 are working, the problem appeared with 3.13.0-45 update of that Ubuntu 14.04.2 LTS and new installation of Ubuntu 14.04.2 LTS is based on 3.16.x that is working. I was not aware of such variation between same LTS regarding point release. Maybe I need to understand how to move a distribution from one point release to the next one. -- 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
