An unofficial (and unacceptable) fix that finally worked for me was.... to switch to Linux Mint 17.1. It is based on Ubuntu 14.04 LTS, so I wonder what they did better, particularly because they seem to be using exactly the same X org and graphics driver versions. X.org 1.15.1 Nvidia: 331.113
Not sure of xorg, but nvidia is definitely from the Ubuntu repos. Things that work correctly now: - booting the system with the second monitor plugged in - no strange temporary artifacts/glitches when changing graphics mode during startup of the x session (however, it also takes *longer* for mint to display the desktop, than for Ubuntu) - booting the system with the laptop lid closed (!) by pressing the docking station power button and using only the big secondary screen (last time I checked this with Ubuntu, I got a permanent system freeze and both screens black) - plugging/unplugging the laptop multiple times from the docking station with external monitor turned on - suspending/hibernating, undocking, resuming (it picks up the new screen config after resume just fine) - suspending/hibernating, docking, resuming -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1382462 Title: Desktop/windows painted incorrectly in dual monitor configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1382462/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
