Yeah - although everything I've read (since originally posting) on this particular problem in relation to ATI cards suggests that the Xinerama+Compiz functionality has never been available for ATI cards and that the only solution for these cards is to use the alternative multi- display mode. This was a bit of a surprise since I don't regularly use ATI cads.
It does seem like a separate & new bug from what you've mentioned. Have you had a look at your package update history to see if anything stands out? -- compiz broken with latest updates and nvidia display config https://bugs.launchpad.net/bugs/558875 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers 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
