Re: [DIGImend-users] Experiencing lag (with Huion 1060)

[Sarah O. <owe...@gm...>]

I'm trying out your patch, and from my git-log, I've gotten the patch
successfully.  From xinput --list, my only tablet option is called HUION
PenTablet, (also the name Gimp gives it), which I think is what it was
called before.  What should the new name be, and where should I see the
change?

Thanks,
Sarah
