The solution for the CTM problem (which is what causes the wacky cursor jumping) is this patch, which was accepted into upstream on 19 Nov 2012; it is not yet in precise-proposed, but I was able to rebuild xorg- server-1.13.0 (from 12.10) with this patch and the problem went away:
http://www.mail-archive.com/xorg-devel@lists.x.org/msg33742.html There is another version of the patch floating around somewhere if you want to fix 12.04. IMHO, there is no good reason to break evdev's swap and invert properties, though. For the simple rotation case, they seem like the obvious right thing to use. Why should they not work? -- 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/774938 Title: Erratic cursor movement when using "Coordinate Transformation Matrix" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/774938/+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
