How to I set up Waltop (Aiptek) Sirius Tablet?

**user333** · February 25th, 2011

Thanks for all you help! I guess I'll just have to play with the drivers a little bit more. And yes, I think the pen is on a click-drag.

The tablet is hardly a few months old(since it was first made available), so maybe if I just wait it will be supported later on.

If I do figure out a way to make this work, where should I post a guide? On a private site, here in the forums, or in the community wiki documentation?

Good luck!

Choice is yours but I'd start a new thread in laptop & hardware and put the HOW TO in the first post.

Well, I have good news

The tablet works perfectly in Natty Beta 1, at least is appears to. I have yet to install gimp or mypaint to test pressure. I'm running Natty on a old laptop to test hardware comparability, and so far all my hardware works, even stuff that never did before, like this tablet

Great!

Looks like Nikolai's kernel patches are doing the trick.

It seems that although EVERYTHING else works, as far as touch areas, buttons, clicking, dragging, pressure, zoom, and pan work, but tilt does not. When the pen is tilted in a painting program, the brush jumps up to the top of the screen depending on how much you tilt the pen, making it useless unless tilt can be disabled. I'm using mypaint, but maybe gimp will be better. For now all the tablet can do is be a mouse replacement, or make very nice paintings that look like bar codes. Oh well. Whatever was done though was an improvement

Do you know of a way to totally disable tilt?

That's not good.

Do you know of a way to totally disable tilt?

No. I suppose there may be a way but I don't know what it is. Looking at wcmUSB.c in /src in the xf86-input-wacom folder I see:

{ WALTOP_VENDOR_ID, 0x502, 200000, 200000, &usbIntuos4 },

Apparently your model Waltop is paired to the Intuos4 which I'm pretty sure does have tilt.

So the key question becomes is your model Waltop tablet suppose to support tilt for the stylus?

If not this is a bug and we need to pair it up with a Wacom tablet that doesn't have tilt. I'm not quite sure how the static struct there works so that might become an adventure.

Yes, basically that is all that's wrong. All other features work. The problem is that the tilt is that the computer miss-understands it, and maps tilt to position rather than changing the brush angle. Would it be possible to create a custom driver based on the Intuos driver that doesn't have tilt?

Yes, the tablet is almost a "clone" of the intuos.

Just to be sure:

Your Waltop tablet supports tilt? That's what Waltop, or whatever the rebrander's name is, says?

If so:

The problem is that the tilt is that the computer miss-understands it, and maps tilt to position rather than changing the brush angle.

I think that might mean the xf86-input-wacom driver is treating the stylus tilt as a Wacom mouse/puck tilt not stylus tilt. If so that's a "bug" in the code and we should report that to linuxwacom-discuss to get it fixed: https://lists.sourceforge.net/lists/...xwacom-discuss

Would it be possible to create a custom driver based on the Intuos driver that doesn't have tilt?

I think so. That's what I was planning to try because I didn't realize Waltop's supported tilt. Looking at the static struct in wcmUSB.c I was wondering what would happen if we changed &usbIntuos4 to &usbBamboo. I'm pretty sure the Bamboo doesn't have tilt. And hoping the difference in resolution isn't a problem.

Yes. It definitely supports tilt. It doesn't say so on the site, but I know from using it.

I'll work on filing a bug later. Just so you know, the Bamboo is not nearly the size of this tablet. The Sirius is 4000lpi and 10"x6" active area, while the Bamboo is 2540lpi and 5.8"x3.6" active area.

Well, it work's fine in Natty now as far as I can tell. Tilt still doesn't work right, but it now is mapped different so if you disable tilt, the pen works fine rather than jump around. It's not a big deal either, because in most cases you NEVER need it. I've tested it with Gimp and MyPaint. I'm using it on the 64 bit version of 11.04, so I'll have to see if it works on 32 bit as well.
