FYI, I have experienced this again. It seems to only happen on resume from suspend.

I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue. Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug: v3.12 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-trusty/ If v3.12 final does not exhibit the bug, we should move on to testing some of the v3.13 release candidates. v3.13-rc3: http://kernel.ubuntu.com/~kernel- ppa/mainline/v3.13-rc3-trusty/ If v3.13-rc3 does not exhibit the bug then test v3.13-rc6: v3.13-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc6-trusty/ If v3.13-rc3 does exhibit the bug then test v3.13-rc2: v3.13-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc2-trusty You don't have to test every kernel, just up until the kernel that first has this bug.

Trying 3.12 now.

Actually.. this is quite embarrassing, I installed 3.12, but my system didn't show a grub menu and I actually booted 3.13.0-24-generic Not sure how that happened, but it actually appears that the issue has gone away somehow.

Hmm, do you still have acpi_backlight=vendor? If not, I guess it would be good to test the 3.13.0-24-generic kernel for a while to ensure the bug doesn't come back. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1309584 Title: [HP EliteBook Folio 9470m Notebook PC] Backlight does not work on intel driver after upgrade from 13.10 - 14.04, acpi_backlight=vendor solves To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1309584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.
