osu!

What works

Everything seems to work fine (every gamemode and mods, multiplayer and online fuctionality), no major glitches and crashes can be found

What does not

There are rows of squares or triangles in any part of the screen, the settings menu works correctly but the bar that separates each section has no text and you can not select a section, the same thing happens with the song selector in the start menu , for some reason, the buttons of ''play, pause, select song, stop'' do not appear but the progress bar of the song does, but it is very strange since it is floating, it now show up properly after using workaround

Workarounds

These workaround is worked for me, but it should work with all across the version of the game 

Before running the installer, using winetricks and install these component:

- dotnet35 (sp1 included) (optional)

- dotnet40 (required)

- gdiplus

- msxml3, msxml4, msxml6

Install these font (i don't know if this is help or not, but it's worked for me)

- corefont, cjkfonts (install from winetricks)

- sudo apt install ttf-mscorefonts-installer

then run the installer, it should run and fix this bug: 

What does not work?: There are rows of squares or triangles in any part of the screen, the settings menu works correctly but the bar that separates each section has no text and you can not select a section, the same thing happens with the song selector in the start menu , for some reason, the buttons of ''play, pause, select song, stop'' do not appear but the progress bar of the song does, but it is very strange since it is floating

It's worked for both 64-bit prefix and 32-bit prefix, no need to change since after you install all of the components and fonts mentions up there, the installer should install and run the game on first try

Also it's a trend to start up faster than Windows (also tested startup time on Windows 10)

What was not tested

A few editor functionality

Hardware tested

Graphics:

• GPU: Intel
• Driver: open source

Additional Comments

Well, it's worked, but i have to disable video due to performance issue (it also cause performance issue on Windows so i thinks it is because my laptop is fairly dated now)

also when switch between app (Alt+Tab), the game seems to confuse between Window and Full Screen mode, causing the game overlap with the GNOME Shell topbar, switch between window mode and fullscreen mode should fix this problem, and the editor menu bar is black sometime (still fuctions as it should)

additionally you can get wine-osu package from ThePooN here: https://aur.archlinux.org/pack...

Last update: 2021-08-06.

1) Get winetricks! (the easy way):

$ sudo wget 'https://raw.githubusercontent.com/Winetricks/winetricks/master/src/winetricks' -O /usr/local/bin/winetricks
$ sudo chmod +x /usr/local/bin/winetricks

2) Create a new 32-bit Wine prefix:

$ env WINEARCH=win32 WINEPREFIX=$HOME/.wineosu wineboot --init

If Wine prompts for installing Mono, click Cancel.

3) Install .NET Framework 4.0:

$ env WINEPREFIX=$HOME/.wineosu winetricks --force dotnet40

4) Download and install osu!:

$ mkdir 'osu!'
$ wget 'http://m1.ppy.sh/r/osu!install.exe' --output-document='osu!/osu!.exe'
$ env WINEPREFIX=$HOME/.wineosu wine 'osu!/osu!.exe'

Run in terminal:

$ env PULSE_LATENCY_MSEC=40 WINEPREFIX=$HOME/.wineosu wine 'osu!/osu!.exe'

Run in terminal (and detach from it so you can close the console window):

$ env PULSE_LATENCY_MSEC=40 WINEPREFIX=$HOME/.wineosu wine 'osu!/osu!.exe' &

Creating a shortcut: 

Create a new plain text file and copy the following:

Save this file as osu!.desktop in the folder ~/.local/share/applications and mark it as executable:

$ chmod +x '~/.local/share/applications/osu!.desktop'

Take the path to an osu! logo image and put it in the Icon field if you want to set an icon for the shortcut.

Arch Linux specific:

• osu! doesn't render anything on screen and exits with some X server error message: install lib32-libxcomposite package:

  $ sudo pacman -S lib32-libxcomposite

• osu! can't connect to internet: install lib32-gnutls package:

  $ sudo pacman -S lib32-gnutls

Japanese characters no displaying correctly: install MS Meiryo font:

$ env WINEPREFIX=$HOME/.wineosu winetricks meiryo

Set language to Japanese to correctly display all kanjis.

This font doesn't include Korean glyphs.

Options menu symbols and audio controls are missing: install GDI+:

$ env WINEPREFIX=$HOME/.wineosu winetricks gdiplus

GDI+ installer is a ~538MB file. If your internet connection is slow or limited, consider instead taking a copy of gdiplus.dll from a Windows 7 installation and copying it to your Wine prefix, and then add manually a Native override for gdiplus.

Open winecfg:

$ env WINEPREFIX=$HOME/.wineosu winecfg

Go to Libraries tab, add gdiplus and set it to Native Then Builtin. Close all dialogs by clicking OK.

Some unusual image formats are not shown when using native GDI+: install windowscodecs through winetricks:

$ env WINEPREFIX=$HOME/.wineosu winetricks windowscodecs

Note: this workaround may break screenshots and interfere with other windows applications installed on the osu! wineprefix when trying to save files. If you need to disable it:

$ env WINEPREFIX=$HOME/.wineosu winecfg

Go to Libraries tab, find windowscodecs and set it to Builtin (Wine). Close all dialogs by clicking OK.

Audio latency, sound distortion or no audio at all: first try setting PULSE_LATENCY_MSEC environment variable to "40" before running osu!:

$ env PULSE_LATENCY_MSEC=40 WINEPREFIX=$HOME/.wineosu wine 'osu!/osu!.exe'

Other values could be tested in order to get lower latency or fix sound distortion/crackling.

Enabling "Audio compatibility mode" in the osu!'s options menu will switch to legacy DirectSound-based audio engine (osu! is now using WASAPI). It can solve some problems but has higher latency and some audio stuttering.

Also check out The Poon's guide and Franc[e]sco's guide.

Frame limiter is permanently locked at 60 fps:

Disable vertical sync by setting vblank_mode environment variable to "0 " before running osu!:

$ env vblank_mode=0 WINEPREFIX=$HOME/.wineosu wine 'osu!/osu!.exe'

This way osu! will not be able to enable VSync at runtime.

Video latency: 

Desktop environments usually draw on screen through a compositor than enable fancy window effects. This may cause lag that you can feel when moving the cursor.

Note: you will prefer to run osu! under X.org since Wayland is not fully supported by most window managers.

• GNOME 3 (Mutter): it should disable it automatically when running at borderless/fullscreen. If you're running on windowed mode or have many monitors, compositing may remain enabled unless osu! window fills all the screen output area.

• KDE Plasma 5 (KWin): press Ctrl+Alt+F12 to disable/enable compositing.You can also add a window rule to block compositing when osu! starts and re-enable when it close.

• Xfce 4 (Xfwm):

  Disable compositing:
  

  $ xfconf-query -c xfwm4 -p /general/use_compositing -s false

  Re-enable compositing:
  

  $ xfconf-query -c xfwm4 -p /general/use_compositing -s true

Other known problems:

• My system is frozen!: if osu! freezes and you lose the control of your system, press Ctrl+Alt+F2 (to enter to a tty) login and enter the following to force closing osu!:

  $ pkill osu

  Press Ctrl+Alt+F1 (or Ctrl+Alt+F7 on some systems) to return to your desktop environment.

• I ran osu but my cpu usage is at 100% and nothing happens: same as frozen system. Open a terminal and run:

  $ pkill osu

  Wait 10 seconds and try again.

• Alt+tab doesn't work when Fullscreen is enabled: if you can't use Alt+Tab hotkey, disable Fullscreen mode inside osu!.

• I can't switch to Windowed mode from Fullscreen/Borderless/Letterbox: close the game. Open osu!.�your_user_name�.cfg in the osu! folder, and edit the next fields:
  Fullscreen = 0
  Letterboxing = 0
  Width = 800
  Height = 600
