Description Lana 2016-02-02 23:38:59 UTC 
I'm using a Wacom Intuous pen small tablet with Krita 2.9.10 and about two weeks ago the pen pressure sensitivity completely stopped working. I've uninstalled/reinstalled multiple times, along with updating my tablet drivers, switching to 32-bit from 64-bit, and even "repairing" Krita. This happens immediately after Krita is opened and has not started working once with any brushes or settings ever since then. My pen sensitivity works on every other program I have, so nothing is wrong with my tablet.

Reproducible: Always

Steps to Reproduce:
1.Open Krita
2.Select brush
3.Make brush mark on canvas with pen

Actual Results:  
Pressure does not respond, leaving mark looking as though I made it with my mouse pad or had pen sensitivity off.

Expected Results:  
The mark should've appeared according to the pressure I put on the pen.

I'm using Windows 8, not Windows 10-- I've heard Krita 2.9 does not work very well on Windows 10, but I am not using that.

Recently, updates to Windows 10 have been breaking Krita's tablet support left and right... Reinstalling Krita will never do anything since you're replacing the old bits on your disk with exactly the same bits. Reinstalling the wacom drivers sometimes helps, but not always. Some people report that removing the Krita configuration from appdata/roaming helps; we don't know why yet because the config file doesn't store anything related to tablet configuration.

Please try:

close krita
press windows-r
type appdata in the run dialog
press ok
navigate to the Roaming folder in the file explorer window 
rename the krita folder to krita_bak
start krita and try again.

If krita now works, please attach the krita_bak/share/config/kritarc file to this bug report.

Despite Boudewijn mentioning windows 10, his instructions also work on windows 8.

We've just been overflooded with tablet pressure issues since windows 10 became widely adopted, on top of genius stopping their tablet driver support, and we've also rewritten tablet support for 3.0, so we get a little scatterbrained in regards to what solution might work for which person. :)

I did what you described above, but it only succeeded in deleting all my custom brushes and presets (I had been trying to do that, so that's a good thing), but the pressure is still not working. Thank you for your help, but I'm probably going to have to wait until 3.0 comes out because you all have much on your plates for bug-fixing with Windows 10 out.
Thank you!

With wacom, pressure support _really_ should work out of the box: if the driver is installed, it should work with Krita. Did the 3.0 pre-alpha work for you?

Does 3.0 final release work for you?
