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-X, 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1428884/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
