Mario Kleinsasser, now that it is known 3.7.0-7.15 is the latest kernel tested not to show the problem, and 3.8.0-0.1 is, the next step is to commit bisect between these two kernel versions (not test different kernel version but different commit versions) following https://wiki.ubuntu.com/Kernel/KernelBisection#Commit_bisecting_Ubuntu_kernel_versions .
Posting to LKML would be largely a waste of time at this point because the commit causing the regression is not known. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1239183 Title: 8086:0a16 [Acer Aspire V5-573G] Black screen on boot due to low brightness setting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1239183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
