Libmeegotouchcore0 by default does not allow orientation of applications so the modified libmeegotouchcore0 enables orientation in the system. the patch file changes all the apps' orientation from locked to open. the patch also allows the user to then blacklist apps that should not be rotated. the landscape .deb file fixes orientation problems by changing the default size of some elements within apps hence displaying properly in landscape mode. For example, calculator, music player have changed to become slightly smaller in landscape so that they fit the screen. Your installation and uninstallation is correct. To reverse the patch simply do: Code: patch -p0 -R < path/file.patch
patch -p0 -R < path/file.patch
