gpothier, thank you for reporting this and helping make Ubuntu better. Could you please provide the information following https:/ /wiki.ubuntu. com/Kernel/ Debugging/ Backlight# Report_ Minimum_ Requirements ?
As well, could you please test the latest upstream kernel available following https:/ /wiki.ubuntu. com/KernelMainl ineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag: testing
needs-upstream-
This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text: testing
needs-upstream-
If this bug is fixed in the mainline kernel, please add the following tags: fixed-upstream fixed-upstream- VERSION- NUMBER
kernel-
kernel-
where VERSION-NUMBER is the version number of the kernel you tested.
If the mainline kernel does not fix this bug, please add the following tags: bug-exists- upstream bug-exists- upstream- VERSION- NUMBER
kernel-
kernel-
If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: unable- to-test- upstream unable- to-test- upstream- VERSION- NUMBER
kernel-

Please let us know your results. Thank you for your understanding.
