Title:
Wacom tablet cannot Map to Monitor properly with dual/multiple
monitors/screens
Status in gnome-control-center:
Invalid
Status in gnome-control-center package in Ubuntu:
Invalid
Status in mutter package in Ubuntu:
Fix Released
Bug description:
In Ubuntu Gnome 17.04, Wacom tablet cannot be properly mapped using
the "Map to Monitor" dialogue provided by gnome-control-center's Wacom
panel. It's always mapped to the first monitor, and the ratio is
incorrect. Both Wayland and Xorg sessions are affected. It has never
happened with Gnome 3.20, 3.22.
From my experience with a similar problem in the past, I suspect the problem
has something to do with:
1) gnome-control-center
2) gnome-settings-daemon (g-s-d)
3) mutter
My hardware setup:
1) Cintiq 13HD (1920x1080, HDMI through adaptor)
2) NEC PA242W (1920x1200, Displayport)
3) Intuos 4M
4) AMD FirePro W5100 (4 DisplayPorts)
Another hardware setup with different GPU and display but has the same result.
1) Dell 2209WA (1680x1050, DVI) (Office)
2) AMD Radeon R7 250E (DVI, DisplayPort) (Office)
Detail:
1) When "Map to single monitor" is OFF, Intuos 4M's cursor moves between both
monitors.
2) When "Map to single monitor" is ON, Intuos 4M's cursor moves ONLY on the
first monitor(that connects to the GPU output of the highest priority).
3) For example, my GPU has 4 DisplayPort outputs, when I turn on "Map to
single monitor", my Intuos 4M is always mapped to whatever on DisplayPort-1
regardless of what I choose in Display Mapping dialogue's output droplist.
4) When a secondary monitor is present, cursor on Cintiq is not aligned with
the pentip. Both of the single monitors are 16:10, Cintiq 13HD is 16:9. I
suspect this to be relevant with this bug.
