>You might be able to WORKAROUND the dimming+freeze issue by disabling screen dim in System Settings (which may have it's own systemd WORKAROUND to get these to take). I'll let you comment further to this.
Yes, this was the easiest workaround but it forbids screen going down. So issue is persistent for that. >If you patch the default Ubuntu kernel with out of tree branches, especially an experimental testing ground like drm-intel-next, it's not supported. For more on this, please see https://wiki.ubuntu.com/Kernel/MainlineBuilds#Kernel.2BAC8-FAQ.2BAC8-DebuggingMainlineBuildsSupport.Does_the_kernel_team_support_the_mainline_kernel_builds.3F . I get this, I just wanted to mention it. Once the "fix" from drm-intel- next eventually gets backported, this could be looked upon. >Also, did this issue not occur for you personally in a release prior to Trusty? Brand new laptop, installed Trusty directly on it. Tried Saucy but had the same issue so went back to Trusty dev build. -- 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/1265544 Title: 8086:0a16 [UX302LG] black screen on boot 3.12.0-7 Status in “linux” package in Ubuntu: Incomplete Bug description: Same description/workaround as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1263015 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.12.0-7-generic 3.12.0-7.15 ProcVersionSignature: Ubuntu 3.12.0-7.15-generic 3.12.4 Uname: Linux 3.12.0-7-generic x86_64 ApportVersion: 2.12.7-0ubuntu3 Architecture: amd64 Date: Thu Jan 2 09:59:33 2014 HibernationDevice: RESUME=UUID=e6458b44-fdb9-4db5-8cac-40ee0bbf9cf6 InstallationDate: Installed on 2013-12-31 (1 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20131231) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 03eb:8a03 Atmel Corp.
