It’s not released yet, but I’ve been keeping my eye on the Open Printer project by Open Tools. You can sign up to get email updates on their Crowd Supply page.
Edit: Sorry, just seeing the no Wifi/Bluetooth, so this might not be the best fit (but it does aim to be fully open source, so maybe in the spirit of what you’re looking for?)
Checked the logs and it didn’t have any insight into the error that I could make out, so the hunt continues!
Thank you! I actually don’t even need to install with the offline installers to launch the game; if I just navigate to where it was installed by Heroic and manually click the executable it will launch properly. I just wanted to get it working through the launcher to hopefully be able to run multiplayer (and maybe have a slightly easier time with mods?) And honestly, it’s just been driving me nuts not to be able to get around this sandboxing in some way. But appreciate your help!
Thank you! I gave it a shot and it still crashed (though it showed a different crash screen, so I think that’s progress? Also if I left the Paradox crash reporter open for long enough it started to play the soundtrack, which was nice).
Just in case anyone else is running into this issue, after many months (and updates to Heroic, the Paradox Launcher, and Linux Mint) I was still having issues with this (though no specific libGLU errors) when I stumbled on another post that mentioned multisampling. My laptop has both an integrated and dedicated GPU and I guess this sometimes causes issues? The solution seems to have been going into settings.txt in the .var/com.heroicgameslauncher.hgl/.local/share/Paradox Interactive/Europa Universalis IV GOG/ and swapping multi_sampling from 4 to 0. Definitely don’t understand why this works (though will try to dive more into it), but figured I’d follow up with what ended up working for me!
