Thank you for that. I've looked at the patch in question (503_fix_masked_transformed_valuators), and it looks plausible that there's a change in behaviour, although I don't see why it would only manifest after a few minutes' uptime.
It appears that we should revert that patch pending further investigation. ** Changed in: xorg-server (Ubuntu Natty) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/791596 Title: Odd Pointer Behavior After Recent Xserver SRU in Natty _______________________________________________ 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
