Tablet pressure not working in Blender (Linux X86-64)

Support Basics & Interface
1

Hi everyone,

I have just set up my Trust TB-5300 tablet in BlueWhite64 12.0 Linux (A 64-bit fork of slackware). Pressure sensitivity works fine in GIMP and in Inkscape, but I cannot seem to get it to work in Blender 2.45 or Blender 2.45.16(SVN) , either in sculpt mode or by clicking the little ‘P’ buttons in paint options in the UV editor.

The tablet is based on the UC-LOGIC Tablet WP5540U, and I am using the Wizardpen 0.5 driver. I have changed the name of the tablet to ‘stylus’ in my xorg.conf - it has made no difference.

Could someone please help me? The relevant udev rules and xorg.conf lines follow, if more information is needed:

Udev rules:

#INPUT DEVICE RULES - udev rules for tablet AND mouse are required for properly-functioning tablet
#
#Genius Wizardpen rule - IT WORKS!!! (finally)
ATTRS{name}=="UC-LOGIC Tablet WP5540U", NAME="input/%k", SYMLINK="stylus"
#
#Lidl (Silvercrest) mouse rule
ATTR{dev}=="13:34", NAME="input/%k", SYMLINK="rf-mouse"

xorg.conf ServerLayout:

Section "ServerLayout"
    Identifier     "X.org Configured"
    Screen      0  "Screen0" 0 0
    InputDevice    "Mouse0" "CorePointer"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "stylus" "AlwaysCore"
EndSection

xorg.conf pointer devices:


Section "InputDevice"
    Identifier      "stylus"
        Driver          "wizardpen"
        Option          "Device"        "/dev/stylus"
	Option		"Mode"		"Absolute"
        Option          "TopX"          "2351"
        Option          "TopY"          "4515"
        Option          "BottomX"       "32739"
        Option          "BottomY"       "32745"
        Option          "MaxX"          "32739"
        Option          "MaxY"          "32745"
	Option		"TopZ"		"5"
	Option		"BottomZ"	"512"
	Option		"MaxZ"		"512"
EndSection

Section "InputDevice"
    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol" "auto"
    Option         "Device" "/dev/rf-mouse"
    Option         "ZAxisMapping" "4 5 6 7"

First question. Does your tablet work in gimp or inkscape?

The answer to that question has already been explained, my friend:

Hi, you can try to swap the lines in “ServerLayout” like this:

Section "ServerLayout"
    Identifier     "X.org Configured"
    Screen      0  "Screen0" 0 0
    InputDevice "stylus" "SendCoreEvents" 
    InputDevice "Mouse0" "CorePointer"          
    InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

My tablet is Genius Mousepen(UC-LOGIC Tablet WP8060U) with the latest wizardpen driver.
Blender worked with pressure, but this also ruins the pressure in GIMP, which is strange. I didn’t figured out this one yet.
Another thing is the horrible stroke when drawing with pressure affecting the brush size in the UV/Image Editor.

I’ll appreciate any help with the stroke jittering.

i have the same problem. i use xubuntu 7.10 upgraded to 8.04. in other application such as GIMP and Inkscape it work just fine but in blender all button act like a middle mouse button, so if i press down the pen, instead of sculpting, what i got is panning the scene and rotating the scene. I already use “stylus” as device identifier. any other way to make this mousepen works?
