Alejandro and everybody who's helped sorted this out: thanks! I was hit by this bug today and it'd would have taken me forever to figure out it was xinerama.
Alejandro, regarding your comment #28, my setup is actually something that I can only do with xinerama, although I only have two monitors: if you want a second monitor in 'portrait' mode (so rotated 90 degrees) while the first is in 'landscape' mode, you're out of luck, as as far as I can tell this can only be done with xinerama. All the best. -- Launching QT apps under Xinerama crashes Xorg : affects SpeedCrunch, KeePassX, Lucky Backup, Pencil, Stellarium, Skype, Google Earth, VLC, Konqueror, VirtualBox, Opera ... https://bugs.launchpad.net/bugs/650539 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. _______________________________________________ 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
