Title: buggy touchscreen behavior affecting desktops, wm and onboard Status in “xorg-server” package in Ubuntu: Confirmed Bug description: On updated Ubuntu 12.04 and 12.10 on a Airis Kira Slimpad tablet, touchscreen is quite unusable. 1/ In KDE, after a while, "taps" on anything that is handled by plasma-desktop seem to be ignored. For example, clicking on the "K" menu does exactly the same thing as moving the cursor with a regular mouse on it : it shows a help bubble and no menu appears. Before that, everything works ok. This seems to be triggered after a specific action. It always happen after dragging a plasmoid of the desktop with the touchscreen or a regular mouse. This never happens after moving a plasmoid of the panel or after trying to move a locked plasmoid. Regular applications continue to work well. The same thing happens in Unity, XFCE doesn't seem to be affected. Usage of a regular mouse is not afected. Restarting X "solves" the situation. 2/ Xfwm is unusable with the touchscreen : cannot click (close, reduce...), cannot move. Compiz works while the bug described in 1/ has not been triggered. After that, Compiz has the same behavior as Xfwm. KWin and metacity are not affected. Enabling/disabling compositing doesn't matter. Using a regular mouse is not affected. 3/ moving and resizing Onboard with the touchscreen is hard. This is done by pressing the "move" button and dragging. When the cursor is out of Onboard (i.e. not in Onboard's surface), this works well. But if the cursor enters Onboard's surface, there is one move and then movements of the cursor seems to be ignored (the keyboard doesn't move anymore). Then, if the cursor leaves the surface of Onboard, Onboard moves anew. Clicking on the "move" button and trying to move Onboard without leaving its surface is completely useless. The cursor has to leave Onboard Surface. Moving Onboard with a regular mouse isn't affected. Multitouch works well at anytime (tested with MagicTouch). Installing debian sid's version of xorg solves all the problems listed above but multitouch is lost (tested on Ubuntu 12.04, not tested on Ubuntu 12.10). ------------------- $ lsusb Bus 002 Device 003: ID 04f2:b213 Chicony Electronics Co., Ltd Bus 003 Device 002: ID 0eef:72a1 D-WAV Scientific Co., Ltd Bus 006 Device 003: ID 0cf3:3005 Atheros Communications, Inc.
