My issue related to my bug #19 has been resolved by unchecking Use XInput under the Options menu in Xournal. -- [hardy] xournal does not give smooth lines https://bugs.launchpad.net/bugs/190778 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 190778] Re: [hardy] xournal does not give smooth lines
Looks like this issue could be related to an upstream bug between Wacom drivers and XOrg 7.3 Here's the upstream bug: http://sourceforge.net/tracker/index.php?func=detailaid=1891727group_id=163434atid=827733 Here's how it specifically related to this issue: There are a few additional issues which cause Xournal to be further confused: 1) the order in which the XInput and Core events are sent has been reversed (now it's Core first, XInput second); this causes Xournal to fail to discard the Core events when Enable XInput is checked and Discard Core Events is unchecked. Thus in that case it tries to process both types of events (the source code modification I'm giving above fixes this). In principle that wouldn't be a problem, except for some reason the XInput events are shifted from the Core events by 1 pixel along each axis... thus resulting in interesting zigzag stroke shapes. 2) in addition, the 1-pixel zigzags caused by the above issue trigger a bug in the GnomeCanvas library (or the rendering library it relies on, I'm not sure); this slows down considerably the graphics processing, and the resulting lag is what causes strokes to sometimes only appear after the pen's been lifted, with extra horizontal segments, etc. As far as I can tell, there's no lag, zigzags, and extra line segments in the other situations. Avoiding those is the main objective of the fixes I suggest above. -- [hardy] xournal does not give smooth lines https://bugs.launchpad.net/bugs/190778 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
