Good afternoon,
This started happening after the Forge update dropped. Whenever I hit the play button on Steam I am greeted with a Java window that says, "We were unable to initialize the game's graphical display." I have followed the steps to ensure compatibility but I am still unable to launch the game. I have also tried uninstalling the game, deleting the game files and installing the game again, and verifying game files integrity through Steam.
My PC specs are:
OS: CachyOS
CPU 9800X3D
GPU: RTX 5080
RAM: 32GB
These are the two warnings I get in the projectx.log file:
2026/05/10 17:39:29:222 WARNING P$a.b: Couldn't create window!
2026/05/10 17:39:29:223 WARNING P$a.b: Failed to create display.
Any help to point me to the right direction would be much appreciated. Thanks in advance.
I have the same issue as well running the game native under Linux with my specs being:
Kernel: 7.0.5-2-cachyos
Desktop Environment: KDE Plasma 6.6.4 (Wayland)
CPU: Intel Core i9 13900K
GPU: RTX 4090
RAM: 32 GB
I have to run the game through Proton to play it under Linux. With newer versions of Proton, I also have performance issues. With version 10.0-4 the game runs better.
