I confirm the bug. I'm using Lubuntu x86_64. I upgraded it from 14.10 to the current prerelease 15.04 and I have that bug too.
My system is a laptop on dock (Lenovo T440p), the dock is connected to a monitor. The bug is only seen if the laptop is docked. The easiest way to reproduce the bug is to log out. ** Summary changed: - Xorg crash + White screen on boot or logout, goes away on mouse click -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1428884 Title: White screen on boot or logout, goes away on mouse click Status in xorg package in Ubuntu: Confirmed Bug description: On a fresh install of Ubuntu MATE 15.04 (packages updates during install allowed, install completed about 1 hour ago) I experience that I cannot log to the user I created during install. When I try, the screen(s) turn white (actually, a very light grey) and stay(s) that way until I click, after which I am returned to the login screen. Guest login works fine. xorg is selected based on a quick read of RindRightPackage. Successful guest login seems to indicate that this is not a driver problem. I have reinstalled, but still experience this problem.
