[Gimp-user] Line thickness not working...?

[AnnaVanity <forums gimpusers com>]

So... I have a Bamboo Splash pen tablet and I have GIMP 2.8.4 on a Windows XP
computer.

I was messing with the dynamics as much as possible, but I encountered an issue:
it only adjusts opacity with pressure, not line thickness

I used Photoshop before and it allowed me to keep the opacity at 100% and change
the thickness of the line with pressure (the way I prefer it)

I need help getting it to that. Help, please?
