Wacom pressure on Linux CentOS7

[Anonymous]

Hi guys; I'm trying to figure out how to enable Wacom pen pressure in Mudbox 2018 & Linux CentOS7.x.

Why it's not working by default?

Thanks.

Hey there,

Could you please tell me if pressure sensitivity is working for you in another program, like Gimp? Unfortunately, Wacom doesn't support Linux any more, so it's down to finding open source drivers. The ones we tried didn't work for Mudbox or for Gimp, so there's not much we can do there. I'm trying to find someone who does have working drivers on Linux.

Hi Jill;

Pen pressure is working fine in Krita and Maya 2018 update 1; but not in Mudbox 2018 update 1.

Thanks, that's helpful. Have you ever had the pressure working in Mudbox on this machine, and if so did anything change lately - e.g. the Linux version?

Hi Jill, I'm working in a studio mainly based on linux and tested this issue in some machines; pen pressure on Mudbox 2015 / 2018.1 Linux never worked for us.

Our Mudbox artist told me that without pressure Mudbox is unusable. As a workaround I setup a Windows workstation, but I want to get it working in Linux.

So next monday i'm going to make a fresh bare metal install of CentOS-7 (1708) and Mudbox 2018.1 or .2.

I will post my results here.

Thanks

Unfortunately in our tests with CentOS 7, we also were unable to get pressure-sensitivity working. I do know of studios successfully using Mudbox with pressure on Linux - I will try to get more details for you.

I have issues with Fedora 27 installation as well.

I have pressure working, but it's bugged.

Best way to describe is that, pressure in Mudbox, work if i use just use slight pressure, pressure range from 0-60% for examle. I can see pressure working and continues stroke. But soon as i press harder at some point, and reach, for example 60% of pressure, brush stop painting like there is no pressure. I tried to play with settings inside mudbox, but no luck. 

Pressure works fine in every other application.

Autodesk should have better support for Linux versions of application, or not making Linux versions at all.

Cheers,

Sorry. I forgot to publish the fix.

There are various problems related to wacom on Linux; currently I'm working on CentOS 7.4.

1. The pressure problem: Newer Linux wacom drivers changed the pressure threshold from 2048 levels to 65K. There are some apps like Mudbox, that are not ready for this change. You can fix it downgrading wacom drivers or updating it to a newer version that supports an option to reenable the 2K setting.

2. UI unresponsive: If you feel the UI is slow an unresponsive in Maya 2018, you need to add an environment variable: 'export QT_COMPRESS_TABLET_EVENTS=1'

3. Wacom hangs and disconnects (on Bamboo tablets): Again is a wacom driver problem; you need to upgrade driver.

UPGRADING THE DRIVER:

1. Build xf86-input-wacom

 - Download package: https://sourceforge.net/projects/linuxwacom/files/xf86-input-wacom/

 - Decompress file: tar xjvf xf86-input-wacom-*.tar.bz2 && cd xf86-input-wacom-*

 - Add dependencies: yum -y install gcc xorg-x11-util-macros xorg-x11-server-devel libXext-devel libXi-devel libXrandr-devel libXinerama-devel libudev-devel
- Buid:
  set -- --prefix="/usr" --libdir="$(readlink -e $(ls -d /usr/lib*/xorg/modules/input/../../../ | head -n1))"
  if test -x ./autogen.sh; then ./autogen.sh "$@"; else ./configure "$@"; fi && make && sudo make install || echo "Build Failed"

2. Build xf86-input-wacom

 - Download pacakge: https://sourceforge.net/projects/linuxwacom/files/xf86-input-wacom/input-wacom/

 - Decompress file:  tar xjvf input-wacom-*.tar.bz2 && cd xf86-input-wacom-*

 - Add dependencies: yum -y install gcc "kernel-devel-uname-r == $(uname -r)"

 - Build:

   if test -x ./autogen.sh; then ./autogen.sh; else ./configure; fi && make && sudo make install || echo "Build Failed"

3. Backup initrd
  sudo cp /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak

4. Rebuild initrd
  sudo dracut -f

5. Fix for pen pressure backwards compatibility

  sudo nano /etc/X11/xorg.conf.d/65-wacom.conf

  Add the lines below:

    Section "InputClass"
    Identifier "Wacom pressure compatibility"
    MatchDriver "wacom"
    Option "Pressure2K" "true"
    EndSection

6. Fix for Maya 2018 UI slow response

  Add the line below to Maya.env

  export QT_COMPRESS_TABLET_EVENTS=1'

Hope it helps.

Thank you Alberto for clearing this out! This make sense. Because that's exactly what i experience, but did not know where it comes from.

I'll try to avoid downgrading drivers, because everything else works fine at the moment. Messing with Wacom drivers is always long adventure i try do avoid if possible 🙂

I'll try to make some workaround. but now i know where to start digging!

Cheers!

I managed to fix pressure issue.

I did not change drivers, i just added lst section for pressure in my wacom
config file and rebooted. Works perfest!
Thanx a lot!
