I have experienced this since 12.04 and it persists in 14.04. Lenovo X1 Carbon (interal Intel graphics) connecting to an external display through mini dp.
It appears to arise through a change in the number of displays connected before a suspend and after a resume. For example, the following sequence: 1) the laptop is put into suspend with no display connected 2) an external display is connected whilst still in suspend 3) the laptop is then resumed. > + Windows moved to wrong workspace after suspend/resume To further confound the issue, windows might be outside the viewable area and need to be moved back into view used Alt-F7 shortcut as no title bar is visible. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/382056 Title: Windows moved to wrong workspace after suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/382056/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
