Posted June 7, 201411 yr This is what I did: * Downloaded the minecraft launcher jar file and placed it in a folder * Set up a .desktop file with the exec parameter set to java -jar pathWhereTheJarIs/theJar.jar * Ran the 1.6.4/1.7.2 version * Download the 1.6.4(latest)/1.7.2(recommended AND latest) forge installer * Ran the file using the terminal: java -jar nameOfForgeInstaller.jar * Selected install client * I then opened the launcher again and ran the newly created profile created by forge. Both versions work as expected on my Windows computer. But when I tried with my Ubuntu computer I get this console output: Development Console: [09:11:01 INFO]: Launching game [09:11:01 INFO]: Unpacking natives to /home/mats/.minecraft/versions/1.6.4-Forge9.11.1.965/1.6.4-Forge9.11.1.965-natives-5224686328135 [09:11:01 INFO]: Reconstructing virtual assets folder at /home/mats/.minecraft/assets/virtual/legacy [09:11:01 INFO]: Launching in /home/mats/.minecraft [09:11:01 INFO]: Half command: /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java -Xmx512M -Djava.library.path=/home/mats/.minecraft/versions/1.6.4-Forge9.11.1.965/1.6.4-Forge9.11.1.965-natives-5224686328135 -cp /home/mats/.minecraft/libraries/net/minecraftforge/minecraftforge/9.11.1.965/minecraftforge-9.11.1.965.jar:/home/mats/.minecraft/libraries/net/minecraft/launchwrapper/1.8/launchwrapper-1.8.jar:/home/mats/.minecraft/libraries/org/ow2/asm/asm-all/4.1/asm-all-4.1.jar:/home/mats/.minecraft/libraries/org/scala-lang/scala-library/2.10.2/scala-library-2.10.2.jar:/home/mats/.minecraft/libraries/org/scala-lang/scala-compiler/2.10.2/scala-compiler-2.10.2.jar:/home/mats/.minecraft/libraries/lzma/lzma/0.0.1/lzma-0.0.1.jar:/home/mats/.minecraft/libraries/net/sf/jopt-simple/jopt-simple/4.5/jopt-simple-4.5.jar:/home/mats/.minecraft/libraries/com/paulscode/codecjorbis/20101023/codecjorbis-20101023.jar:/home/mats/.minecraft/libraries/com/paulscode/codecwav/20101023/codecwav-20101023.jar:/home/mats/.minecraft/libraries/com/paulscode/libraryjavasound/20101123/libraryjavasound-20101123.jar:/home/mats/.minecraft/libraries/com/paulscode/librarylwjglopenal/20100824/librarylwjglopenal-20100824.jar:/home/mats/.minecraft/libraries/com/paulscode/soundsystem/20120107/soundsystem-20120107.jar:/home/mats/.minecraft/libraries/argo/argo/2.25_fixed/argo-2.25_fixed.jar:/home/mats/.minecraft/libraries/org/bouncycastle/bcprov-jdk15on/1.47/bcprov-jdk15on-1.47.jar:/home/mats/.minecraft/libraries/com/google/guava/guava/14.0/guava-14.0.jar:/home/mats/.minecraft/libraries/org/apache/commons/commons-lang3/3.1/commons-lang3-3.1.jar:/home/mats/.minecraft/libraries/commons-io/commons-io/2.4/commons-io-2.4.jar:/home/mats/.minecraft/libraries/net/java/jinput/jinput/2.0.5/jinput-2.0.5.jar:/home/mats/.minecraft/libraries/net/java/jutils/jutils/1.0.0/jutils-1.0.0.jar:/home/mats/.minecraft/libraries/com/google/code/gson/gson/2.2.2/gson-2.2.2.jar:/home/mats/.minecraft/libraries/org/lwjgl/lwjgl/lwjgl/2.9.0/lwjgl-2.9.0.jar:/home/mats/.minecraft/libraries/org/lwjgl/lwjgl/lwjgl_util/2.9.0/lwjgl_util-2.9.0.jar:/home/mats/.minecraft/versions/1.6.4-Forge9.11.1.965/1.6.4-Forge9.11.1.965.jar net.minecraft.launchwrapper.Launch [09:11:01 INFO]: Looking for orphaned versions to clean up...

Reading the Development Console, I assume the launcher can't find the main start file. The vanilla versions of the game works perfectly. Is there any Linux user that have managed to run forge? Am I doing something wrong? System properties: OS Name: Linux OS Version: 3.2.0-48-generic OS Arch: i386 Java Version: 1.7.0_55 32-bit
June 8, 201411 yr [09:11:03 INFO]: Client> 2014-06-07 09:11:03 [sTDERR] Caused by: java.lang.ClassNotFoundException: org.objectweb.asm.ClassVisitor Whatever launcher you are using is not downloading all of the libraries nessasary for the game to start, or your ASM library is corrupt, try using mojang's official launcher. I do Forge for free, however the servers to run it arn't free, so anything is appreciated. Consider supporting the team on Patreon
June 8, 201411 yr Author That's strange... I am using the official launcher. Does it say in the console (before the "Starting game" entry) if it fails to do this? What may be causing it to not download the libraries?
