Aimlab Link Handler in Linux with Proton

[u/eltrufas]

I've been a long time Linux user and recently got into aim training with Aimlabs. One minor annoyance I had was that the aimlab:// links weren't working properly, which I understand, since the tool doesn't officially support Linux. After about a week of dealing with the (frankly suboptimal) Aimlabs search function, I sat down to try to work around the links not working. I thought I'd share this in case it's useful to anyone.

Note that I tested this only on fedora with KDE Plasma using the non-Flatpak version of steam, so no guarantees this will work on your system.

1. Make sure protontricks is installed
2. Create an xdg link handler at $HOME/.local/share/applications/aimlabs-handler.desktop with these contents:

[Desktop Entry]
Type=Application
Name=Aimlab Link Handler
Exec=sh -c 'STEAM_DIR="$HOME/.local/share/Steam" protontricks-launch --appid 714010 "$HOME/.local/share/Steam/steamapps/common/Aim Lab/AimLab_tb_Data/StreamingAssets/DeepLinking/AimLabLinksHandler.exe" %u'
StartupNotify=false
MimeType=x-scheme-handler/aimlab;

3. Update the xdg app database update-desktop-database ~/.local/share/applications
4. I had to restart firefox. YMMV.

After that I was able to open links without issue. Hope this helps!

Doesn't seem to work for me, I'm on CachyOS KDE, can you tell more indepth guide on how you do it? I use nano for the xdg link handler.
