Plz redirect me to where I can get assistance with this... Hello, Using the xinput cmdline tool I'm fully able to leverage my understanding of the HUION H420 Pen and it's properties. When using xfconf-query I don't believe the data is being constructed correctly for passing to XChangeDeviceProperty.
https://gitlab.xfce.org/xfce/xfce4-settings/-/blob/bd2da4ed559eec4144ed8ea6092642deee63de9f/xfsettingsd/pointers.c#L866 I'm wondering what the format of this buffer should be? I'm trying to setup a translation matrix for a tablet(actually the pen). In xinput I get `Coordinate Transformation Matrix (157): -1.100000, 0.300000, 1.500000, 0.700000, -1.900000, 1.000000, 0.000000, 0.000000, 1.000000`, the command issued is `xfconf-query -c pointers -p /HUION_H420_Pen_Pen_0/Properties/Coordinate_Transformation_Matrix -n -t double -s -1.1 -t double -s 0.2 -t double -s 0.3 -t double -s 0.4 -t double -s 1.5 -t double -s 1.6 -t double -s 0.7 -t double -s 0.8 -t double -s -1.9` Obviously it looks like xfconf-query's backed is expecting two values per cell? Because of the code in pointers.c it's impossible to send more than 9 values, the counts won't match and the function returns early. I therefore think that the buffer's format is incorrectly understood. I'm looking for clarification on the buffers format. Thanks. _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel
