I simply meant that in both 12.04.2 and 14.04 I had used the Nouveau driver. My statement that "The bug is reproducible if I use either driver." was meant to be a summary of the situation, not a contradiction of my testing in 12.04.2. 12.04.2 works fine (as did 13.04 before I upgraded to 13.10). 13.10 and 14.04 do not work - I can easily reproduce the bug in those versions.
That said, I am not going on a wild goose hunt and trying random Nvidia drivers to see if it fixes anything - you're guessing at what the problem is, when the evidence I've provided you so far indicates that the problem happens if I use the Nvidia driver or the Nouveau driver. Unless you can give me a good reason to try a different driver, it's a waste of my time. -- 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/1257327 Title: 10de:06fd [Dell Precision T5500] Ubuntu 13.10 dual monitor screen lock causes windows to disappear off-screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1257327/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
