Re: [Linuxwacom-discuss] Fwd: Bamboo P&T CTH-661 - Cursor jumps using finger touch function

[Favux ... <fav...@gm...>]

Sorry, didn't reply to all.

Thanks Guenther, that helps.  I went back over the BambooPT HOW TO
thread, about the last 18 pages, starting around 3-4-11 which is when
the first complaint about the pointer jumping appeared.  Of the 3 to 4
folks who complained two have the 0x0d6 and one the 0x0d8.  Fennec had
a 0x0d6 but once he got it working (with help from you Alexander?) he
didn't mention a jumpy pointer or random left clicks with touch.

So that brings us up to 3 0xd6's and 2 0xd8's (if Roland has one) and
maybe 1 unknown complaining about pointer jumpy.  All new models.
