This bug seems to be same as: https://bugs.freedesktop.org/show_bug.cgi?id=63900
Workaround: Place the external monitor on the left side and laptop monitor on the right. This way the laptop monitor with "invalid" width won't miss align the picture on the external monitor. ** Bug watch added: freedesktop.org Bugzilla #63900 https://bugs.freedesktop.org/show_bug.cgi?id=63900 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1280690 Title: 2 pixels shift on the second screen (extended desktop) Status in “xserver-xorg-video-ati” package in Ubuntu: Confirmed Bug description: Hello, I have 2 screens and there is a 2 pixels shift to the right on the display on my second screen (see attached picture).
