OpenJDK7: Cannot find display (minecraft)

Fri, 22 Mar 2013 17:43:55 +0000

There is a problem with Java finding the correct display on my dual monitor setup in i3. When I`m trying to launch Minecraft, I get a black window when the game starts and it puts out: Exception in thread "Minecraft main thread" java.lang.ExceptionInInitializerError at net.minecraft.client.Minecraft.a(SourceFile:208) at avv.a(SourceFile:56) at net.minecraft.client.Minecraft.run(SourceFile:507) at java.lang.Thread.run(Thread.java:722) Caused by: java.lang.ArrayIndexOutOfBoundsException: 0 at org.lwjgl.opengl.XRandR$Screen.(XRandR.java:234) at org.lwjgl.opengl.XRandR$Screen.(XRandR.java:196) at org.lwjgl.opengl.XRandR.populate(XRandR.java:87) at org.lwjgl.opengl.XRandR.access$100(XRandR.java:52) at org.lwjgl.opengl.XRandR$1.run(XRandR.java:110) at java.security.AccessController.doPrivileged(Native Method) at org.lwjgl.opengl.XRandR.getConfiguration(XRandR.java:108) at org.lwjgl.opengl.LinuxDisplay.init(LinuxDisplay.java:618) at org.lwjgl.opengl.Display.(Display.java:135) ... 4 more I`m running i3 version 4.5.1.

It seems that it rather is a problem of lwjgl which is being distributed with Minecraft in an older version that has some bugs with multidisplay-setups. Replacing it with a newer version helped me.

i3 doesn’t modify any RandR information, so this seems unrelated to i3 on the first glance. Unfortunately Minecraft isn’t open source, so we can’t look at what it does…
