[Kernel-packages] [Bug 1663989] [NEW] Screen flickering
You have been subscribed to a public bug: Since upgrading from ubuntu 16.04 to 16.10 the screen (backlight?) is flickering irregularly. It only happens with kernel 4.8.x. No flickering problems when manually switching back to kernel versions 4.4.x at boot.
