You filed the bug in the right place, and you're being asked for legitimate debug data as a result. Moving the bug somewhere else won't get it fixed :) So, what you need to do in simple terms is:- 1. Identify and download a kernel build 2. Install the kernel 3. Reboot into the new kernel 4. Test while running the new kernel 5. Clean up. For 1:- mkdir ~/kernel_test cd ~/kernel_test wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc2-trusty/linux-headers-3.15.0-031500rc2-generic_3.15.0-031500rc2.201404201435_i386.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc2-trusty/linux-headers-3.15.0-031500rc2_3.15.0-031500rc2.201404201435_all.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc2-trusty/linux-image-3.15.0-031500rc2-generic_3.15.0-031500rc2.201404201435_i386.deb For 2:- cd ~/kernel_test sudo dpkg -i *.deb For 3:- Close all your applications and reboot. Hold down the shift key as soon as the computer powers up, to get the grub menu. When you see the grub menu, use the arrow keys to highlight the 3.15-rc2 kernel and then press [enter[ to boot from it. For 4:- Test using the brightness keys Report back on the bug if it's working or not. For 5:- Reboot back to your old kernel using the same method as step 3:- but boot to the old one, not the new one sudo apt-get remove linux-headers-3.15.0-031500rc2-generic linux-headers-3.15.0-031500rc2 linux-image-3.15.0-031500rc2-generic rm -rf ~/kernel_test Done. Hope that's helpful Cheers, Al. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
