You can add elementaryOS 0.4.1 to the working distros
it's really just based on Ubuntu 16.04 LTS and I've only tried it within a VM but it does its job
(no comment on latency or performance because VM tests are not to be trusted a lot but it worked just fine)

Is there actually a distro or repository where one can test wayland?
I'm actually really curious how (bad) it actually turns out to be (for playing osu) in its current state

So I tried to install everything through the POL way on Ubuntu 17.10 on my Laptop and I'm kinda stuck with an error message about wine not being able to use TrueType Fonts because of a missing/insufficient Freetype version (starting with the registry editor not working properly and continuing with spitting out errors during dotnet45 install and crashing osu bevor it can download/install anything)
I don't know if I screwed up myself somewhere or if there's some dependency or basic package I overlooked, I reinstalled libfreetype6, wine and POL but still nothing doing

Using wine 1.8.3 results in massive stuttering for me. Updating the version to 3.1 solves that problem, while still having the same amount of latency (somewhat bad, i'm using wayland)

Mint 18.3 here, i tried all possible methods but osu keeps restarting on "We are updating your game"

i recently successfully installed osu on linux, and here are some neat tips i've collected from mostly franc[e]sco and thepoon, the two osu-on-linux professionals:

1) you can get the same latency as from wine 1.8 on recent wine versions (i've tested this on 3.5) if you use alsa and not pulse. to do this without completely removing pulse, you will need to 

WINEPREFIX=whatever WINEARCH=win32 winetricks sound=alsa

WINEPREFIX=whatever WINEARCH=win32 pasuspender -- winecfg

and in the Audio tab, set the proper Output device for your system, click Apply, then Test Sound to make sure it works. Now, you can run your game with pasuspender (so for example, 
WINEPREFIX=whatever WINEARCH=win32 pasuspender -- wine 'C:\\osu\osu!.exe'
) and it should work fine!

2) if you use a wacom tablet and you do not drag, you may notice that you go out of your tablet's range much easier than on windows. this is because of a tablet feature where it has two different states of being in proximity, and in range, in which the pen is still close enough that the tablet detects it but not as close as "in proximity". the current linux wacom drivers completely ignore this second state, and only update your pen's location if it's in proximity. but the maintainer of the linuxwacom project has done some work on it (i'm not sure if they're planning to merge it (perhaps as a setting) to the main driver), and this branch is the fixed driver where you can lift your pen as high as you could on windows.

3) approach circles look weird? limit your fps.

while the game is not running, open your osu!.user.cfg, and set the CustomFrameLimit to the highest fps your computer can handle stably. Note that osu! normally shows how many milliseconds it takes to render a frame instead of the fps in the "fps counter", so the math is 
fps = 1000/(how many milliseconds it takes to render one frame)

rewrote most of the guide for wine 3+ with a lot less complicated steps

also added a fix for having both the main menu top-right icons and working japanese fonts thanks to _goeo's testing as well as the wacom hover distance fix

Hey,
Thanks for having written this - and keeping up to date.

That said, it doesn't seem to work on my side - under Debian stable (stretch).
I've tried so many tutorials but I'm really stuck. Since I wiped my Windows partition in December, I didn't find a way to play osu! again and it's quite troublesome to me.

Here's a video showing my problem, just dumbly copypasting your commands :
https://youtu.be/_cDb7CYPcjE

As usual, wine is going nuts and I don't have a clue of what's happening.
I know your tutorial isn't especially designed for Debian systems, but if you have any idea of where I can start digging to have a chance to make it run, please let me know.
Thanks for your help.

thanks for debugging my guide

looks like I made a copypaste mistake, the osu!install command is supposed to be 

WINEPREFIX=~/osu-wine WINEARCH=win32 wine ~/Downloads/osu\!install.exe


other than that it looks like the other steps went fine

Oh my god, seriously, thank you.

I was thinking the installation failed because of all the errors wine was throwing in the console, without even trying to understand why there was a command attempting to open osu!install.exe with regedit.

Can't thank you enough, I'll be able to click circles again now.
Feel free to contact me if you need to debug anything under Debian.

hello there. i have got arch linux. i was about to throw this away because no internet connection on wine. but now i figured how to fix that. write "sudo pacman -S lib32-gnutls" and i guess your issue will be fixed.

https://osu.ppy.sh/ss/10759611 do you think i can do anything with this?

specs: HP ProBook 450 G1 (arch linux + KDE)
processor : i5-4200M @ 2.50 ghz
graphics: intergrated
ram: 3.7gb
thats all sadly.

i have got better performance on win.

you messed up a lot of the links when you edited the post to newest revision



they turned out like this . . " https://github.com/Francesco149/loli-ov ... sound.conf "

" https://wiki.archlinux.org/index.php/Ad " --> ur alsa arch wiki link lol

newcomers might be confused
uhh I think that's the new forums' fault, I'm pretty sure I pasted the links correctly lol will try to fix

EDIT: fixed them, thanks for the info

wine staging is updated for wine 3.5 / 3.6 now

staging might improve quality of gameplay as it offers improvements for "realtime" and "I/O heavy" games/apps
good to know! but staging never affected performance on osu for me and I think arch is the only one that has up to date wine staging so i decided to leave it out

EDIT: guess I'll add that staging is fine too if desired

ah, I thought arch had fixed this by now, guess I'll readd this to the guide, thanks for testing

if you already tried everything on https://wiki.archlinux.org/index.php/intel_graphics I recommend trying a barebones window manager like jwm ( https://wiki.archlinux.org/index.php/JWM ) or a lightweight DE with no fancy effects like lxde

KDE plasma is gpu accelerated and might be eating fps

if that still doesn't help, most likely the intel drivers aren't quite as good for your gpu :[ you can also try installing a cutting edge kernel and mesa for newer drivers but from what i can see the stock arch packages for those are already quite cutting-edge

after a bunch of testing wine 1.8.3 still seems to offer far superior audio latency with winetricks sound=alsa flag


idk how to change winealsa.drv on newer versions of wine, i'm guessing that's the problem ? ?
well, we had a bug report on wine's tracker about it and never managed to figure it out even though I remember bisecting commits and finding exactly which commits broke it

idk, maybe it's cause I'm on pure alsa now but 3.5 latency feels the same as what I had back when I was on 1.8.3 and pulseaudio
