This looks very much like you've installed packages from the xorg-edgers PPA which have been multiarched and then downgraded; that's (unfortunately) not supported.
Alternatively, you might be mixing versions - the nvidia packages in xorg-edgers are multiarched, and they won't install with mesa from Natty. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/833841 Title: libgl1-mesa-glx alternative link To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/833841/+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
