Public bug reported:
Binary package hint: wacom-tools
Intrepid (with wacom-tools-0.8.1.4-0ubuntu3) is installed on an HP
TC4200 tablet pc. With the attached xorg.conf, I observe the following
behavior:
- suspend/resume machine without any display/pointer rotation => pen
works correctly, with the cursor calibrated to the position of the pen
on the screen
- rotate the display, without rotating the wacom pointers (xrandr -o
right). Then suspend/resume the machine and rotate the display back to
landscape (xrandr -o normal) => no calibration problem
- rotate the display and the wacom pointers (xrandr -o right &&
xsetwacom set Stylus Rotate cw && xsetwacom Eraser Rotate cw). The
pen/cursor calibration is fine. Then suspend/resume the machine => The
pen/cursor calibration is off. When the pen is at the center of the
screen, the cursor is approximately 2 inches up and to the left of the
center (with the screen in portrait mode). Rotating the screen and
pointers back to normal landscape position (xrandr -o normal &&
xsetwacom set Stylus Rotate none && xsetwacom Eraser Rotate none) the
calibration continues to be off, with the cursor up and to the right of
the pen. If I move the pen to the top left corner of the screen
(landscape), the cursor is right under the pen. As I move the pen to
the right, the cursor gradually moves faster to the right than the pen.
Starting from the top left corner again and moving the pen down, the
cursor moves slower toward the bottom of the screen than the pen.
- rotate only the wacom pointers (xsetwacom set Stylus Rotate cw &&
xsetwacom Eraser Rotate cw), then suspend/resume the machine, then
return the wacom pointer rotation to normal (xsetwacom set Stylus Rotate
none && xsetwacom Eraser Rotate none) => The pen and cursor show the
same problem as described above (poor calibration between pen and
cursor).
So, the calibration is only affected when the wacom pointers are
rotated. It seems that the wacom pointers get the dimensions of the
screen mixed up after a suspend/resume if they are rotated. After each
of these cases, restarting the xserver restores the proper calibration.
It also does not matter if the TopX, TopY, BottomX, BottomY lines are
enabled or commented in the attached xorg.conf, the same behavior is
observed.
This is a regression as it worked correctly in Hardy.
