[SOLVED] Genius G-Pen F610 - WizardPen Tablet Issues (Cursor Shakes)

Hello fellow archers,

I have a Genius G-Pen F610 tablet, it works great in Windoze XP, and I almost have it working in Arch. I am using the 'wizardpen' package from the AUR since the same driver from the Google code page wouldn't compile for me...

Anyway, I have the thing detecting input separate from my mouse, hover movement works, clicking works, pressure sensitivity even works, but for some god unknown reason:

The mouse cursor just WILL NOT STOP SHAKING.

I have tried everything I can think of in xorg.conf, and nothing has fixed this problem. At one point I got the shaking to go diagonal instead of horizontal, but that must have been a fluke because after restarting X with no config changes it went back to horizontal.

Basically I have noticed that the further away from the tablet I hover with the pen, the wider the shake, and the closer brings the opposite. Also, when I press down, or 'click', the cursor moves to the far right of the shaking pattern and stays there, but as soon as I pick up the pen, it starts shaking again. I figured out that it is taking the correct input for at least one cycle, then shifting to the right when I tried to open programs in the gnome menu, and they immediately turned to desktop icons no matter how fast i clicked.

Thank you for any help you can give,

Mitch

Here is my xorg.conf:

search for an option called "threshold"... it defines the minimum amount of pixel movement to be recognized as movement for the pen. Normally, you can set it to both the x and y axis.

Re: [SOLVED] Genius G-Pen F610 - WizardPen Tablet Issues (Cursor Shakes)

Ok, so I looked for a threshold option in the wizardpen driver docs, and couldn't find a mention. I tried it anyway, and had the same problem... I finally did get rid of the problem though, and I think I know what it was (for anyone with the same issue on a tablet).

The shaking went away after I commented out all of the coordinate lines in my xorg.conf file, but came back when i uncommented them. I found out that hal had a premade policy file for my tablet (In /etc/hal/fdi/policy/), and that the coordinates the driver was sending and the ones that I set in xorg.conf were ever so slightly different. This is what was causing the cursor shaking. The driver would feed X a set of values periodically based on the zutodetected tablet area, but X would default to the xorg.conf tablet area settings on click, which were different. I have since simply removed the lines in xorg.conf describing the tablet and moved all the configuration to HAL. It took some extra work, but it's worth it.

EDIT: For anyone who stumbles on this thread: I have upgraded to the latest 'xf86-input-wacom' package which supplies drivers for WALTOP tablets (Basically all Genius tablets), and I no longer have this issue. The threshold options now apply perfectly, just put them in the HAL or Udev policy file depending on what you use.

I am using the 'wizardpen' package from the AUR since the same driver from the Google code page wouldn't compile for me...

Hey, I updated the driver (but created a different package) to their last version from Launchpad: http://aur.archlinux.org/packages.php?ID=42671 - works with xorg-server 1.9.x. Just letting you know.
