How to run Minecraft on Ubuntu 10.10

Install the openjdk
Copy and paste this into the terminal window (Click Applications –> Accessories –>Terminal)

 sudo apt-get install openjdk-6-jre openjdk-6-jre-headless

Then just download the game to your home folder and run at the terminal

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


If you have trouble you could try this, it appears as if the filename has changed. This is due to Linux being case sensitive.

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

      1. UMM im running my ubuntu on my usb stick cause my hard drive is corrupt so does Ubuntu already have this on it so I only have to install it?

    1. The file name is case sensitive. When you first download Minecraft, the JAR file is named “minecraft.jar”. Just minimize the M in Minecraft.jar in the command.

    2. I had the same issue. It was a simple mistake. If you are copying the entire line (like I did) Then you will have a space at the start of the command line. This space needs to be removed for it to work correctly. This is due to Linux sensitivity.

    1. Your not hacking, your just entering a command. Some linux users still use it often, but I avoid it. You can also start the program by right clicking on the minecraft.jar file, going to properties, going to the permissions and check “Allow exicuting file as program” then go to the open with tab and click the dot next to “OpenJDK.” Then click okay and from then on you just need to double click to run the program.

    2. You can’t run minecraft without java it’s the same as running ubuntu without a computer. Do you think that is hacking? Hacking is not putting simple cmd snippets into the terminal btw why do you think is the terminal called terminal not hackterminal?

      1. Perhaps you should look at what the first meaning of hacking is before you go screaming at people? ‘A hack is an implemented work-around in order to get something to work. For example, running a windows program on a Linux distro through the use of WINE is, in itself, a hack’.

If you’r one of the poor Windows users you will never understand this cause you’r a Microsoft slave… YEAH, slave!! Cause there you can’t do anything and if you try to do anything you are called a ‘hacker’ (gnegne) and put into jail! FUUUUUUU
        That’s just beacuse people are ignorant and the think that ‘hacker’ means ‘black hat hacker’ (at least that’s how it is on Windows)… while most of the ‘hacker’ (“A person who enjoys exploring the details of programmable systems and stretching their capabilities, as opposed to most users, who prefer to learn only the minimum necessary.” [wiki quote]) on ubuntu are just ‘white hat hacker’ 😛

      1. Ubuntu is the only proper OS for people who just want to use their computer and not worry about it crashing all the time and don’t want to pay a shitload of money for a mac. Mac is a good OS, but the hardware is overpriced. Windows is just what the name suggest: full of holes. Ubuntu is the product of thousands, maybe millions of people who were sick of being dependent on commercial OS’es. It’s the only OS that was made by and for users/developers, and on top of that: it’s f*cking free. What more could you possibly ask for?

    3. Because the Minecraft guys slacked up and didn’t prepare an installer for Linux. Creating a .deb and a .rpm would have been the right thing to do but even a zip with a startup script would have been enough. A five minute solution.
      Furthermore they did that silly mistake with the uppercased minecraft.jar. They’re probably not used to Linux so we have to work a little more to offset that.

  1. I havn’t got my minecraft computer on me but i assume that you did not download minecraft to your home folder.

    You could either move it from where you downloaded minecraft.

    or

    Adjust the part of the command which points to where minecraft is saved.
    eg

    Change the Minecraft.jar bit of the command (which assumes its in your homefolder)
    to
    Downloads/Minecraft.jar
    I think this is where firefox puts it by default.

    Give this a whirl and see how you go.

    You could check that you have the correct drivers installed for your graphics card.

    You may have better luck using the proprietary drivers.

    If you are on Ubuntu click the

    System Menu –> Administration –> Additional Drivers

    Have a look here and see if there are any options that work better for you.

  11. The crash I was getting above can be fixed by adding a -jar to the java command; however, the game only runs for a couple seconds, then crashes anyways, even with the notch recommended memory specifications. The game runs fine from inside firefox though, oddly enough, so there has to be something we’re missing on that command line.

    Sadly, upon getting the game to launch, I was prompted to pay. For a beta. That is not how beta testing has ever ever worked. I’m not entirely sure I will like this game, and I’m not forking out $15 to help the developers pan out the bugs, especially with a 100 posts about how poorly it works on Ubuntu 10.10.

      Microsoft have nothing to do with this game for 3 reasons:

  27. Alright… I got all happy when I got Minecraft downloading and all, and then after i click login to play (and after force update) it crashes and gives me this message in both Terminal, and Minecraft:

  30. I looked went through the processes that you described and was able to get minecraft running in a way. The problem is that when I log in and try to go under multiplayer it wont let me type in an IP address. When I then tried to see if the single player would work it let me in but then wouldn’t let me back out. Meaning, once it loaded I was unable to walk or move aside from clicking with my mouse and destroying things. I was not able to then exit the program without forcing my computer to restart. Since I was not able to get out of the minecraft window I wasn’t able to see if there was an error though it looked like there was not a new line after it opened. Is there anyway that someone can help? I would really like to join my friends on this amusing game. Please and thank you.

    How about this then? I don’t see anyone else having this error code.
    Ubuntu 10.10, fresh install
    Sun Java JRE, fresh install
    Generally everything is fresh, tried every command line etc. Above.
    My brother runs Minecraft on Ubuntu 10.10, on his laptop. So, memory problems?

    I can run Minecraft perfectly on Minecraft.net, but I can’t run it on my desktop, anyone else having the same problem? :/

  33. Has anyone tried actually running the minecraft.jar file as an executable file? If it says that it can’t be run as an exe, I found that if you right click it, click Properties, Permissions, and check the box ‘Allow executing file as a program’. Then you just have to open it with the Java that comes with Ubuntu. Works for me, but it might not for everyone. I’m running Ubuntu 10.10 Netbook Edition, just so you know.

  34. yeah it’s works well, move it in the home folder and REMEMBER Ubuntu terminal is case sensitive and therefore check if minecraft.jar was written with small or big M.
