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 Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
