I'm writing this post for everyone having troubles with tablet pressure sensitivity in Inkscape after installing/upgrading to the newest version of Ubuntu 15.10.
There is (I think) better and easier solution to well known bug http://bugs.launchpad.net/inkscape/+bug/790130. Overlaying scrollbars are still the issue, but they are easy to disable without removing any packages (like in the old solution suggested by the users http://www.inkscapeforum.com/viewtopic.php?t=18959).
To easily disable overlaying scrollbars I used Unity Tweak Tool.
[Step 1] [OPTIONAL]
To install the tool open terminal and paste the command:
Code: Select all
sudo apt-get install unity-tweak-tool
Or do the same via Ubuntu Software Center by typing "Unity Tweak Tool" and clicking "Install".
[Step 2] [Disable overlaying scrollbars]
Run the Unity Tweak Tool and select System -> Scrolling. Then under Scrollbars part select the option Legacy. That's it!
[Step 3] [Enable tablet in Inkscape]
Plug in your tablet and launch Inkscape. In menu tab select Edit -> Input Devices... and change Mode for your tablet input devices from Disabled to Screen. Restart Inkscape and the pressure sensitivity should work again
It worked for my Wacom Intuos 5 tablet. Whoever finds this post I hope it will help you too
