Code: Select all

LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$JAVA_HOME/lib/amd64/:$JAVA_HOME/lib/i386/:$JAVA_HOME/jre/lib/amd64/:$JAVA_HOME/jre/lib/i386/" exec nice -n -4 java -Xmx1024M -Xms1024M -cp PATH_TO_MINECRAFT_LAUNCHER.jar net.minecraft.LauncherFrame $@

Try this, rev. Put it in a shell script and run.

nice: cannot set niceness: permission denied
Somthing like that it flashes real quick had to do it a lot to try and read it

Nice is a command that assigns process priority. But I guess Ubuntu is more strict about this command, so try it without nice:

Code: Select all

LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$JAVA_HOME/lib/amd64/:$JAVA_HOME/lib/i386/:$JAVA_HOME/jre/lib/amd64/:$JAVA_HOME/jre/lib/i386/" exec java -Xmx1024M -Xms1024M -cp PATH_TO_MINECRAFT_LAUNCHER.jar net.minecraft.LauncherFrame $@

this just closes the terminal without any message at all. Isn't there any way i can access the java options like the mac discription above? Ubuntu sure seems pretty impossible for doing anything. Does any one else use it? Do these ides work for other people? I just went out and bough some new ram going from 1G to 2G yet i'm stuck using 200M on minecraft. Not that it's ubuntu's fault i totaly put all the blame on mojang. I'd say blame java but it's mojang's dumbass' that decided to use java in the first place. I get the feeling this is hopeless

Finally got it. As the problem before was that it couldn't find jar file i just put it directly in the home folder and tried from there. So here's the final process i used to get it to work.
1. Put minecraft launcher (minecraft.jar) in the home folder
2. Make a text file that reads:

Code: Select all

java -Xmx1024M -Xms1024M -jar /home/stoningpot/minecraft.jar

of coarse stoningpot being your own user name
3. Set text file as executable in it's properties
4. Execute the text file. Does not need to be in same folder since i used the whole path

I just knew there had to be any easy fix to the can't find jar file problem
