Comment 2 for bug 974887

There are many bugs in the touchscreen pointer emulation code. I have developed many fixes for them and sent them on to <email address hidden>. I also created one big patch for the precise xserver. I have uploaded it to ppa:chasedouglas/jupiter as xorg-server 1.11.4-0ubuntu11~jupiter5. Once it has built, please test it out.

Note that there appears to be a bug in gnome panel where it will no longer show the menu after tapping it. I have traced the server and found that it still does send events and receive replies from the panel, so I believe this is a bug in the panel itself rather than the server. The server is still working properly if you can interact with other objects like the desktop.
