Public bug reported: Binary package hint: xorg
The flickering occurs continuously in both the login screen and after login. This problem occurred under 10.10 (see https://bugs.launchpad.net/ubuntu/+bug/666441), but it was every 8-10 seconds. This problem does not occur in a dual-booted Windows environment. Changing resolution and refresh rate does not appear to affect the bug. The monitor is a Samsung 763MB CRT.
