I'm sorry but I'm not sure I fully understand the instructions... I'm really bad at computing :(
So just to make sure... I have to download this one: linux-headers-3.18.0-031800rc5-generic_3.18.0-031800rc5.201411162035_amd64.deb <http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc5-vivid/linux-headers-3.18.0-031800rc5-generic_3.18.0-031800rc5.201411162035_amd64.deb> then install it with " sudo dpkg -i " and that's it ? Or do I have to install linux-image-3.18.0-031800rc5-generic_3.18.0-031800rc5.201411162035_amd64.deb <http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc5-vivid/linux-image-3.18.0-031800rc5-generic_3.18.0-031800rc5.201411162035_amd64.deb> as well ...? I managed to change the brightness thanks to Xcaliber, but I'd like to fix this problem anyway...
