WOW, I'm really frustrated. It is so hard to find anything about this program, and documentation is so old that it is wrong. I'm noob probably, I was using photoshop but that was few years ago (And PS is super intuitive). I saw so many positive user statements but this app is so hard i can't even...

Let's go back to the topic:
Windows 10
Krita 4.0.1
XP-Pen Deco 01

Fresh Install. Just bought the tablet (for a child). Stylus buttons are overwritten (they stack both actions actually) by Krita with middle click and left click on mouse.
It is frustrating because, functions don't work properly and I can't create shortcuts like fe. shift + space + stylus button (1 or 2) to rotate 15* etc.
Opening popup pallete changes color because it clicks left click additional.

How to disable this?
Additionally i might ask few out of topic questions that are not so important:
- What brushes to use? What are the best? I want to tag them and be able to fast use. Saw on YT brushes like pencil, ink.brush.25, bristles.hairy, airbrush but they don't exist or don't look the same when painting with them.
- I don't get blending/mixing paint it was different tool in PS, but here it is a brush, but i can't find good one.
- What smoothing should I use? Basic seems choppy.
- I have 8 buttons on tablet and 2 on pen. What configs are the best? Right now I use: brush, eraser, brush size, color picker,zoom, rotate, mirror, undo and Pen on No Action because Krita overwrites it anyway.

Yes I'm fresh and don't know how to use graphic tablet properly. Thanks in advance.

You do realize it's not the best way to start don't you? Actually there's plenty on information on the net if you search and the documentation isn't really that old, there's some pages that have been added/updated for Krita 4 already but those that were still (mostly) right havn't. Writing documentation takes time and (unfortunately) is often the weakest part of FLOSS development but Krita isn't that bad. Also i never found PS to be super intuitive, it does have it's PS way of working and if you're used to it you'll find other applications hard to understand but doing anything beyond very basic photo manipulations in PS takes a lot of learning. Enough rant.

What kind of "fresh" install? It took me a fresh windows install to get my xp-pen (mostly) working with Krita. Before that i couldn't get pressure sensitivity to work no matter what i tried. My windows 10 had been updated from 7 to 8 to 10 with some wacom drivers that stubbornly refused to be uninstalled so i had to start over from scratch.
It's now mostly working because just like you the stylus buttons are acting weird. I guess i'm lucky since mine are doing the "hand" move canvas and opening the pop-up as i would have choose but in reverse order. I even tried to set the stylus buttons to "no action" in the driver settings but i still get those 2 default actions. It's really weird and i tested several applications, only Krita does this so i doubt the issue is (only) with the xp-pen drivers (if you search a bit you'll find comments that their drivers are ****, but i've had my shares of troubles with wacom drivers). If anybody can help with this issue i would sure appreciate and if any developper wants some additional informations i can try to run any sort of diagnostic tool (available on windows) required to get this sorted. Apart from that, my tablet is working very well now that i've cleaned the mess my OS had become.
Unfortunately i havn't found anything in the Krita settings that might solve the issue. You might try setting your xp-pen driver to windows-ink mode and set Krita's tablet input APi to Windows 8+ input (EXPERIMENTAL). Maybe it could help you. Otherwise maybe try to set your stylus buttons to "no action" and see if at least it prevents double-action but it didn't change anything for me.

- What brushes to use? What are the best? I want to tag them and be able to fast use. Saw on YT brushes like pencil, ink.brush.25, bristles.hairy, airbrush but they don't exist or don't look the same when painting with them.

Krita 4 comes with an all new set of brushes assembled by David Revoy. He's a very talented illustrator who, in the past, distributed his custom set of brushes on his blog. His brushes were so popular that the Krita developers asked him to choose the set of brushes for Krita 4. You can still find the old krita 3 brush set in settings > manage ressources but the brushes most people use are probably the new ones.
That being said, brushes are THE big topic with Krita. They are quite different from PS brushes and it takes time to learn how they work but the brush engine is also very powerful once you learn how to use it. Have a look at their description (https://docs.krita.org/The_Krita_4_Preset_Bundle), try to look at some videos (here's the link to David Revoy's channel : https://www.youtube.com/user/DeevadRevoy/videos , he shows some brushes that should be similar to those you have in the new Krita, but not every one of them unfortunately) and more importantly : experiment.

- I don't get blending/mixing paint it was different tool in PS, but here it is a brush, but i can't find good one.

The closest to the "finger" tool of PS would probably be the blender : basic tool but you have a lot of blenders in Krita which is actually a good thing. You can also customize them to fit your need, you're not stuck with a finite amount of tools. Of course, the price to have all those options is you need to spend some time to learn/experiment and find the best tools for your own need.

- What smoothing should I use? Basic seems choppy.

Well, it depends how choppy your hand is Once again, experiment. The stabilizer gives some really nice results but isn't good for every job (if you need to draw a lot of small zig-zag lines for example, don't use it.

- I have 8 buttons on tablet and 2 on pen. What configs are the best? Right now I use: brush, eraser, brush size, color picker,zoom, rotate, mirror, undo and Pen on No Action because Krita overwrites it anyway.

You lucky man, i have only 6. Well, once again it really depends on you own workflow but given your issues with the stylus i would at least use one to rotate, one to pan, one to zoom and one to call the pop-up. I also like to have a button for ctrl-z. A useful one with Krita could be numpad /, it switches between your current brush and the previous one so you can, eg, switch between and ink brush and eraser easily. This is my full set-up but you'd still have 2 more buttons for whatever task you want.

You are right, that was not good way to start a topic. I searched a lot about this, let's call it bug, but could not find any useful info. I tested few free apps like this, but there is always something missing. Krita is almost like PS, for me it is only usable app, the rest it's just weird and with out of date hud. The only disadvantage of Krita is that it is hard to adapt, even with documentary. Everything would be perfect if not for that tablet behavior.

Windows 10 is few days old, full install on empty drive, and xp-pen drivers and Krita installed the same day. Everything works the way it is supposed. Only Krita overwrites pen, and it seems to be only on canvas.
My stylus also is "hand' pan move and popup pallete, but clicking button for pallete changes color sometimes. I assumed that barrel buttons are middle mouse and right mouse, but with left click added in both.
Stylus button are set for no action, and Krita changes that, changing to windows ink and Windows8+ input and restarting Krita, changes only that I need to put pen on tablet with buttons, but they are still the same.

Thanks for links and tips they were useful. The best hotkey that I didn't know about is that numpad / and ?/ also works.

I think if You change middle button and right in Canvas settings, you would get them reversed, but I'm looking for a way to disable the buttons in Krita and still be able to use mouse normally and choose action with my pentablet drivers.

If you disable Windows Ink, that might have a good effect for you when using the tablet with Krita. The settings icon is on the system tray at the right side?

For what it is worth, the 3.3 brushes are still accessible from settings->manage resources and there move the 3.3 bundle to the lefthand column.

For the stylus side buttons, you should be able to delete all actions associated with them in settings->canvas input settings.

Docs.krita.org is kept pretty up to date, considering there's only three people working on it. The real problem here is a combination of the shortcut settings being a very messy part to krita (there just hasn't been any time to unify shortcuts and canvas input settings since the inception of them) and tablet drivers being super confusing. Krita is supposed to follow the tablet settings, but if Krita is overriding them, then the tablet is not reporting the buttons correctly to Krita.

What do you mean? Delete middle and right mouse action? This will also affect my mouse, besides i actually want the same effect or similar to that. For some reason Krita adds something like left button click to both stylus buttons, and that changes my color when clicking 2nd stylus button when I want the popup pallete.

When i delete canvas right and middle action (pan and pallete) and for example change that to normal keys and then change function in my driver for that keys it does not eliminate that it still stacks clicks on top of it. Krita canvas still thinks it is middle and right click, even that this action do nothing.

I should be able to add more modifications to pen buttons the way you suggested, but it would still click on color for example, and because this weird behavior is only on canvas i would lose right click function out of canvas.

EDIT. Is there any way to change brush size with Shift + Middle button? Mouse buttons seems to not work when editing shortcut.
