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 Ubuntu-X, 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 To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm-gtk-greeter/+bug/1531224/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
