Tested on Ubuntu 8.10 and 9.04

java -Xms800M -Xmx800M -classpath .:lib/jinput.jar:lib/lwjgl.jar:lib/lwjgl_util.jar:lib/World of Minecraft.jar:lib/minecraft.jar
 -Djava.library.path=native/linux Main
(all on 1 line)

I found it to be a little laggy on my machine so I cranked the ram usage up to 800 rather than 512 default which smoothed everything out.

If you wish you can put it back to default -Xms512M -Xmx512M

The code i gave you in my post works fine for me.

I was lazy and just edited the .bat file.

You can just double click on the bat file and select "Open in terminal" and she's good to go.

Try redownloading, I think your lwjgl might be corrupted. I'm not sure though, as I'm not really a java person, but that seems to make the most sense.

Hey, i've tried both versions of the script (on Ubuntu 4.09), but when i try to run them, they give me the following errors:

guyboy@ubuntu:/media/TREKSTOR/un$ ./minecraft-osx.sh
bash: ./minecraft-osx.sh: /bin/sh<#: bad interpreter: No such file or directory

or

guyboy@ubuntu:/media/TREKSTOR/un$ ./minecraft-osx.sh
bash: ./minecraft-osx.sh: /bin/sh^M: bad interpreter: No such file or directory

=S I don't know too much about Linux.

I'm having a similar problem. I'm unable to allocate enough memory.
I've been running :
ava -Xms512M -Xmx512M -jar /home/USER/desktop/minecraft.jar
as well as
ava -Xms512 -Xmx512 -jar /home/USER/desktop/minecraft.jar

My problem is that I have an insufficiently large memory allocation and that the game crashes pretty much as soon as I have 2-3 items or alter the terrain. Could some one give me a script to help me run? I tried :
#!/bin/sh

java -Xms800M -Xmx800M -classpath
.:lib/jinput.jar:lib/lwjgl.jar:lib/lwjgl_util.jar:lib/World of Minecraft.jar:lib/minecraft.jar
-Djava.library.path=native/linux Main

But the computer didn't recognise the  "Main" and nothing happened. Help please...
