Can confirm this bug persisted on my Thinkpad L430 with Xenial 16.04.1 with kernel 4.4.0.81. However, it was fixed by manually updating the kernel to the latest version (4.8.0.58) by running
sudo apt-get install --install-recommends xserver-xorg-hwe-16.04 Now, I don't see the flicker anymore. This thread was quite useful for the suggestions regarding updating the kernel. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1531224 Title: lightdm-gtk-greeter flickers once little after lightdm starts Status in LightDM GTK+ Greeter: New Status in xserver-xorg-video-intel package in Ubuntu: Confirmed Bug description: Bug context: · Arch Linux x86_64 4.3.3-2-ARCH · systemd 228-3 (using lightdm-plymouth.service) · plymouth 0.9.2-8 (compiled from AUR) · lightdm 1:1.16.6-2 · lightdm-gtk-greeter 1:2.0.1-2 At the end of boot process, right after plymouth splash, lightdm starts normally and the GTK+ greeter login screen is shown for about 1 second, but then the screen instantly flickers (goes black) and the greeter is redrawn. From here on, everything works flawlessly, but the brief flickering is certainly annoying. This happens every time and no other greeter I have tried presents this issue, so I can confirm it is lightdm-gtk-greeter-related.
