hi,
my krita was working fine, but today i installed 3.0 (from 2.9) and pen pressure disappeared (strangely, i needed to also change some settings in Gimp, but there at least i got it to work). anyone know how i can fix it?

thank you

It is a good pratice to post the OS and the Tablet Model when asking questions like this.
By the fact that it also affected GIMP, it can be a driver issue.
I had it a couple times and it was aways the driver.
If you are on Windows with Wacom tablet, try reseting the tablet settings.
I'm talking form my personal experience, so I may be wrong.

In my experience, every time we get a report that krita stops recognizing the tablet as a tablet (which is what "no pressure anymore" means -- we are getting sythetic mouse events instead), it's a driver problem. Windows 10 especially breaks wintab drivers quite regularly with OS updates.

thank you. i'm talking win10, with a wacom cintiq 22 touch

the problem seems to have solved itself after a reboot.
my experience in general is that the whole thing is not entirely stable - don't know if has anything to do with krita, or with the windows drivers in general. i often have small problems, like not being able to touch the border of the screen, bad calibration, etc. Most of the time i'm able to fix them quickly by recalibration, or unplugging and replugging the port, but obviously it would be good to have a more stable configuration.
(i guess this is all quite vague, sorry about that)

Windows drivers.... My bet is on them every time, because Krita really doesn't do anything fancy: we follow wacom's development guide to the letter.

yeah, no doubt. i can't even get my wacom and krita installed on my main computer (no pen pressure, after months of investigating). i'm using a secondary one, where it does work.
