I can also confirm this bug. I have a 12"x12" Wacom ArtZ II tablet connected to a serial port. The lag is extreme - around about a third of a second. (Whether or not my USB mouse is connected makes no difference.) As AISmithee says, the eraser moves fine and pressing the tip or a stylus button momentarily eliminates the lag. So does crossing the proximity threshold.
I have an almost fresh install of Ubuntu 9.04 on a crummy old 1.5GHz Althon thingy. (The motion on Ubuntu 8.04 was fine except for the way it often slew to the corners or edges of the screen and generated hard clicks.) (I've added a dummy xorg.0.conf in case a rogue robot is stymieing this bug report. No such existed in my almost-fresh Ubuntu 9.04 install.) ** Attachment added: "Dummy file, in case a bot demands a file I didn't have already" http://launchpadlibrarian.net/29993511/xorg.0.conf -- wacom stylus slow sluggish unusable https://bugs.launchpad.net/bugs/365997 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
