Minecraft Forums

Hi all! I have a PowerPC PowerMac G5 Macintosh which I am trying to run Minecraft on. I have OpenJDK 7 installed, but I am getting some wierd errors while trying to launch the launcher from the JDK. Here is the error:

xception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

at net.minecraft.LauncherFrame.main(LauncherFrame.java:159)

The command I am running is as follows:

java -Xmx1024M -Xms512M -cp minecraft.jar net.minecraft.LauncherFrame

So yeah, if a Java guy could help me out, it would be great. I have helped other people in the 10.4 thread and this is a totally new error. It would really help everyone! Thanks!

You won't be able to play 1.6+, but update LWJGL manually.

I just tried that, I get:

com.Mojang Specifications.Minecraft.Minecraft[271]: Exception in thread "Thread-6" java.lang.UnsatisfiedLinkError: /Users/keaton/Library/Application Support/minecraft/bin/natives/liblwjgl.jnilib:  no suitable image found.  Did find:  /Users/keaton/Library/Application Support/minecraft/bin/natives/liblwjgl.jnilib: no matching architecture in universal wrapper

So that means 2.9.0 is not compatible with PPC. I might try using LWJGL that is with minecraft and taking the one file which is incompatible. Also, when I run Minecraft with openJDK PPC 7, I get:

net.Minecraft.LauncherFrame
Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable.

Just a little different from above.
