I have a Huion H420 tablet. I've installed the drivers, and the tablet shows up in the devices. I've put the mode on "screen" and changed the pressure to "3", but when I go to draw, there are no lines. If I press down with the pen, there'll be a dot, but only a dot and no line. On other programs the tablet and pen work perfectly with pressure and everything. It just doesn't seem to be working on GIMP. Help?

same problem with me

I'm suggesting you to use version 2.8.18 for a while untill the development team fix this bug on 2.8.20 https://download.gimp.org/mirror/pub/gimp/v2.8/windows/

Oh man... it's half working for me. Now it's drawing, but there's no difference in pressure. I tried out the tablet in another program and that still worked. So it's just GIMP that's not quite doing it for me. Maybe I should use an older version than 2.8.18?

If you choose paint brush tool there's dynamic setting in option tool to change the pen pressure style.

Thanks for the suggestion. I've done that though and it still isn't working. I downloaded a few other art programs and it's not working on those either. I guess it's something to do with the tablet, not GIMP, so I messaged Huion and hopefully they can help me out and not let my money be wasted on a tablet that doesn't work -_-

I just wanted to leave an update in case anyone else is still having this problem.

I emailed Huion support and here's the instructions they sent me:

Here's a step by step to reinstall, please try and see if it works(If you are using Mac system, please skip 3-4 steps): 1. Log out the Huion driver, close all drawing programs you are running, close your anti virus software. 2. Uninstall the Huion driver from control panel. 3. Find the "TabletDriver" folder from C:\Program files\ and delete it. (If you are not able to find this folder, that means you have deleted it already, and you may skip this step.) 4. Go to C:\windows\system32 or C:\windows\system64, find "wintab32.dll" and delete it. 5. Unplug the USB cable.
6. Download driver from Huion website (https://www.huiontablet.com/support/) and install it as an Administrator. 7. Reboot the computer and wait until it finishes rebooting. 8. Plug the tablet back in.

I had a few issues with their instructions. The wintab32.dll file was actually in C:\windows\sysWOW64. That was the first thing. Also, the file wouldn't delete because it was open in Malwarebytes Tray Application. I couldn't for the life of me figure out how to close the program, so I ended up deleting Malwarebytes off my computer for the moment. But then the file still wouldn't delete because it was open in OneDrive, then DropBox. So I exited those programs as well.

After getting all the original Huion files off my computer, I downloaded the driver from the link they gave me. I forgot to restart my computer and tried out the tablet on GIMP and krita and had the same problem as before. Then I realized I needed to reboot. So I did that, and then everything worked perfectly!

I really don't know what I did wrong when I first installed the drivers, but I guess if the problem is solved now, I don't need to dwell on that.

For the record, I still have the older version of GIMP installed (2.8.18) that someone else on this thread suggested. This version also helped me with another little issue I had where the icons were too small for a normal human to see.

So hopefully if anyone else has this same problem, they can follow these instructions and have the good luck I did!

Peace!
