Paint Tool SAI has been running for a long time under linux with the help of Wine. But till date, Wacom tablet pressure is not handled properly. This problem is referenced as bug11846, opened in 2008 in WineHQ Bugzilla and still open.
Hopefully, the PlayOnLinux team has issued a patch for Wine version 1.5.5 that allows Paint Tool SAI to handle tablet pen pressure. But this patch doesn't seem to work with latest Wine versions.
So, this specific wine version has been added into PlayOnLinux database under 1.5.5-SAI name.
This guide explains all the steps to :
- check if your Wacom tablet is recognised on your system
- install PlayOnLinux and the patched Wine 1.5.5-SAI
- install Paint Tool SAI
- declare SAI files interaction for Gnome desktop
It has been tested with a Bamboo Fun CTH-661 tablet under Ubuntu Precise 12.04 Amd64 (Gnome 3.4) and Ubuntu Gnome 13.10 Amd64 (Gnome 3.8).
It should be applicable to many other Wacom tablet models and other Linux flavours.
