Linuxwacom Discuss,
I've been using the Linuxwacom drivers successfully since version 0.6.x.
When I say "successfully", I mean that I use my Wacom tablet as my
primary pointing device for my OS (Ubuntu).
However, when I use graphics programs, I've had a strange error. I first
noticed it in GIMP, and thought that the problem might be application
specific.
Recently I tried Photoshop (under Wine), and got the exact same problem,
so it seems to me to be unlikely that both graphics applications are
having the exact same problem The common element is the Wacom tablet, so
that's where I'm assuming the trouble lies.
The issue is with the pressure sensitivity.
I open a graphics app (GIMP or Photoshop), and open a new document. I
select a brush, and have pressure sensitivity turned on. Over time, (not
even a minute) as I use the brush, I have to press harder and harder to
get any output. Eventually, the pressure sensitivity gets to the point
where no matter how hard I press it no longer draws anything.
Closing and reopening the application does not help. The problem
persists across sessions. Also, so far as I can tell, if I open up
Photoshop, use the brush to where it no longer inputs, then open up
GIMP, it will not input. Vice versa seems to be true as well.
The only way I get pressure sensitivity back to where I can draw again
is if I reboot my system.
Looking on the Linuxwacom manual pages, I came across this command:
xsetwacom set Stylus PressCurve 0 15 85 100
But when I tried it, it said:
Error (2): WacomConfigOpenDevice: No such device
Set: Failed to open device 'Stylus'
Which is odd, because my Wacom tablet seems to be working to at least
some degree.
Has anyone experienced anything like this, or might be able to suggest
what I might check to solve this? Pressure sensitivity seems so
tantalizingly close to working, and it would be a huge help to me as I
work in graphics a lot.
Thank you for any advice.
Linuxwacom driver is 0.7.2, which is the latest available in the Ubuntu
repositories.
Here are some configuration lines from my xorg.conf file, which I feel
might be relevant (what exactly is "PressCurve" doing, anyway?):
Section "InputDevice"
Identifier "stylus"
Driver "wacom"
Option "Device" "/dev/input/wacom"
Option "Type" "stylus"
Option "USB" "on"
Option "Mode" "Relative"
Option "PressCurve" "50,0,100,50"
EndSection
Section "InputDevice"
Identifier "eraser"
Driver "wacom"
Option "Device" "/dev/input/wacom"
Option "Type" "eraser"
Option "USB" "on"
Option "Mode" "Relative"
EndSection
Section "InputDevice"
Identifier "cursor"
Driver "wacom"
Option "Device" "/dev/input/wacom"
