I'm a total beginner with Gimp and I can't figure out how to enable pressure sensitivity for my pen. Pressure sensitivity for Gimp works fine under Vista but I'm trying to make the switch to Linux Mint permanently. Other programs like Mypaint have sensitivity under Linux so I don't know why there's a problem with Gimp. I have the correct Wacom driver installed in Linux so that shouldn't be the problem. What is the setting I need to change in order for Gimp to recognize pen pressure?

Go to Edit/Preferences, Input Devices, and press the "Configure extended input devices" buttton. Does you tablet show up there?

Yes it's listed there. But now I can't even get to that dialogue box anymore. My mouse clicks don't register and the pen doesn't work anymore when I'm in the edit/preferences dialogue box. But when I go back to the drawing area it works fine. Gimp is acting really buggy in Linux. I'll figure it out. I think I caused it when I reinstalled the Wacom drivers from the supplied disk.

Every time I try to change the input device to Bamboo pen stylus it doesn't take effect. The save button doesn't seem to work for some reason. It's a mess but I'll figure it out eventually. I'm going to reinstall the recommended Linux drivers for my tablet.

I am so frustrated now with Gimp. I'm about to give up entirely on trying to get Gimp to work in Linux. I don't even know how to completely uninstall Gimp in Linux. If I could do that I might be able to fix the problem by reinstalling it. Is this a typical bug with Gimp? If all else fails I'll go back Vista for good.

Do you have pressure sensivity in other Linux apps?

(from memory making my Bamboo work in Kubuntu+Gimp was completely painless, I had more problems under XP).

If you don't mind reinstalling:

Connect your Wacom tablet and other things like printer etc to your computer.
Now start your Mint installer and it will see what's hooked up and install what's needed.

Ok Gerard, I'll follow your tip. I just hope Linux doesn't try to reinstall everything and erase all my settings and software...

Ofnuts: Yes, I have pressure in Mypaint running under Linux so other programs work fine in Linux. I went to that website a few times to download the driver that was suggested. Only problem is I don't know how to install a program manually under Linux. It's not as easy to work with as Vista is.

And speaking of Mypaint, I've noticed a bit of a difference with the response time of Mypaint under Linux as opposed to running in Vista. It feels like the pen responds much faster under Linux and it feels like the real thing especially when I'm doing quick strokes of the pen. There's a velocity setting that can be adjusted to allow the stylus to really feel like an ink pen. Honestly, I would say drawing and painting in Mypaint feels more realistic than it does in Gimp. There seems to be a larger selection of brushes to choose from as well. But of course I know that you can do much more cooler stuff in Gimp with all of its filters and adjustments.

I'll post again if I can solve the problem. I just want to paint and stop messing with Linux!

one of our artist's uses Mypaint and then uses GIMP for editing later.

I'm getting very similar behavior with Natty:
cat /etc/*release*

mypaint show great pressure sensitivity , gimp pretty much nothing. One tip , using the gimp brush dynamics I set pressure to control size ... so you can then look back and see how big a spot the paintbrush can create ... I did manage a few 'small dots' by pressing very gently (can't reproduce that now) I also played with xwacom command to set pressure sensitivity ... seemed to have no effect.

Does it require a combination of the Wiki - if you have any other ideas?

made some small progress. The man page for wacom (the driver) says:

Option "Device" "path"
sets the path to the special file which represents serial
line where the tablet is plugged. You have to specify it
for each subsection with the same value if you want to have
multiple devices with the same tablet. This option is
mandatory.

Mine says:

It used to read /dev/input/event* , but when I looked there I saw:

Two wacom devices ... I don't have a touch so I made the edit above:

MatchDevicePath "/dev/input/wacom"

Now wehn I go to the extended device settings in gimp .. I see less devices:

just pen and pen finger (no stylus) ..I manage to get two or three levels of pressure detected (using the size trick above)

I feels like the scaling is wrong ... so if I do:
$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]

when I touch the pen tip I see a[2] which seems to be what gimp takes to be pressure ... but I only ever see 3 or 255 ... again feels like scaling... (in the driver)

Hi graemev,
If you use KDE as desktop you might want to install this:
http://kde-apps.org/content/show.php?ac ... ent=114856
It has instructions how to install in Ubuntu.
Works fine in my setup.
Another thing you could do is open a terminal and issue this command:

This what I get:

Hope this is of use to you.
Gerard.

Thanks gerard82. I don't use KDE .. I did use xsetwacom .... however it's looking like my actual device is not being recognised:

$ xsetwacom --list devices
$ < ie no output>

However:

Now if I look in:

/lib/udev/rules.d/69-xserver-xorg-input-wacom.rules

I see lots of ATTRS{idVendor}=="056a", ATTRS{idProduct}=="XXXX", SYMLINK+="input/XXXXXX"

Type rules but NONE have idProduct of 00d4 .. so it looks like my device lacks a rule.

So at the end it just does this ...

# Convenience links for the common case of a single tablet. We could do just this:
#ATTRS{idVendor}=="056a", SYMLINK+="input/wacom-$env{WACOM_TYPE}"
# but for legacy reasons, we keep the input/wacom link as the generic stylus device.
ATTRS{idVendor}=="056a", ENV{WACOM_TYPE}!="touch", SYMLINK+="input/wacom"
ATTRS{idVendor}=="056a", ENV{WACOM_TYPE}=="touch", SYMLINK+="input/wacom-touch"

Hence my two devices (even though I only want wacom/stylus ) ... I can hack my way around this but I'm guessing if it's not here it's probably not in the kernel module either (too new?) ... I've downloaded the source and I'll have a play see if I can add it.

Yep , there it is in: wacom_wac.c max press = 255

and tapping the stylus I can see it hit 255 with very little pressure ... hence the mapping provided by xsetwacon pressure graph has very little to play with ... I THINK this device sends 0 2047 ... but I can't find any informatin to that effect now ... gurrr

Is xf86-input-wacom installed?
Here's a link that got me going.
