[Solved] Minecraft hangs on black screen after login

I am able to launch the client and login, but immediately after login the window goes black and hangs, throwing this exception:

Exception in thread "Minecraft main thread" java.lang.UnsatisfiedLinkError: /home/cyrus/.minecraft/bin/natives/liblwjgl.so: /home/cyrus/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

Based on suggestions elsewhere, I tried replacing the lwjgl files in the .minecraft directory, to no avail. I also re-downloaded the Minecraft client. Incidentally, the browser client also hangs when I try to use it. I'm not sure if I'm reading the error right, but it seems like it's having a problem with 64-bit architecture.

Re: [Solved] Minecraft hangs on black screen after login

Make a script with the following in it and use that script to launch the game.

export LD_LIBRARY_PATH="/opt/java/jre/lib/amd64"
java -Xmx1024M -Xms512M -cp minecraft.jar net.minecraft.LauncherFrame

And then it happened... a door opened to a world... rushing through the phone line like heroin through an addict's veins, an electronic pulse is sent out, a refuge from the day-to-day incompetencies is sought... a board is found.

Re: [Solved] Minecraft hangs on black screen after login

I'm not really sure if I should post this here, but I'm having the exact same problem he had but when running that script I get

Error: Could not find or load main class net.minecraft.LauncherFrame

What could this mean? My problems started with last 24 after updating my packages. Here is a log of yaourt/pacman updating the packages in case this might be useful:

Re: [Solved] Minecraft hangs on black screen after login

Put this code to your ~/.bashrc worked for me:

export LD_LIBRARY_PATH="/usr/lib/jvm/java-7-openjdk/jre/lib/amd64/"

Re: [Solved] Minecraft hangs on black screen after login

Sorry to open up old wounds but a better way to do this would be

sudo su -c "echo [path to java]/lib/amd64(or i386) > /etc/ld.so.conf.d/java.conf"
sudo ldconfig -v

so for me it is

sudo su -c "echo /opt/java/jre/lib/amd64 > /etc/ld.so.conf.d/java.conf"
sudo ldconfig -v

but if I was the root user then it would be (still in my case)

echo /opt/java/jre/lib/amd64 > /etc/ld.so.conf.d/java.conf
ldconfig -v
