Tekkit doesn't work

[Dash16]

The upside down thing is a bug in the latest version of LWJGL and certain Mac graphics chipsets. (From what I hear, integrated Intel chipsets.) As far as I know, the only fix for that is play full screen, or downgrade to the version of LWJGL that is included with Technic modpacks.

Your java issue is likely because you installed the java 7 jdk, you may still have java 6 installed on the system but if the java -version command is returning the string your is, Java 7 is prioritized. There are a couple terminal commands we can run to get some more information about your java installations, if you'd like. Or, you can play fullscreen until the LWJGL guys figure out what the bug is and fix it.

no no, I would like to fix the java problem either then doing something with LWJGL :)

If you are going to keep the latest version of LWJGL, then you are going to have to play full screened unless you like playing upside down. The way I see it, you have 2 options:

1) Keep Java 7 installed and default, keep LWJGL 2.9.0 and play full screened.

2) Remove Java 7, ensure Java 6 is the default JRE and downgrade LWJGL to the Technic shipping version.

1 or 2, take your pick. A 3rd (pointless) option would be to downgrade Java to 6 and keep the updated LWJGL, which has the upside down bug. You gain nothing really by doing that.

Me personally, I've seen some performance issues with Java 7 + LWJGL 2.9.0 and am sticking with Java 6 and the Technic shipping version of LWJGL for as long as possible.

Yeah thats what Im saying, I want to downgrade Java, but not sure how, in that case I need someone that can help me to truly delete java 7, downgrading LWJGL is the easiest part

[knatte12]

Can u help me with the commands?

[Dash16]

I can, but it can be complicated. There isn't a simple uninstaller, you've got to remove the .jdk directory from the computer, and in some cases fix the symlink to point back to the correct install of java. If you had Java 6 on your system already, and you installed the Java 7 JDK from Oracle, it should be a simple matter:

1) Open /Applications/Utilities/Terminal.app

2) Type: which java

3) Type: ls -la /Library/Java/JavaVirtualMachines

4) Type: ls -la /usr/bin/java

Respond to this thread with the response to each of those commands (2-3) and I'll see what I can do.

I did some research and the way to fix the upside down is to use fn-f11 and that will make it FULL screen, but can you share some in depth information on how you got the launcher working but it launched upside down? I'm having the same problem and I would like to know how to at least get it launched

Hey I was having the same trouble and I'm on a Mac. Bothe Tekkit and Hexxit weren't working like discribed above, but I tried this

1. Download LWJGL from here (scroll down to the download link).
   
2. Open the bin folder of the tekkit folder within .technic (or just technic if your using a mac).
   

[more important instructions]

1. After you opened the bin folder, open lwjgl-2.9.0.zip, extract all its contents, and open the the folder called jar (the location is different depending on how you extracted it).
   
2. Now copy these files and only these files from the jar folder into the aforementioned bin folder: lwjgl_util.jar, lwjgl.jar, jinput.jar.
   
3. Now exit the jar folder and open the native folder (the called "native" from the .zip) and within it, there's folders named after operating systems. Choose the folder corresponding to whatever OS you use and copy all the files within.
   
4. Paste these files in the folder named "natives" in bin and test your Tekkit.
   

And it worked just fine for the Hexxit, so I tried the same thing for Tekkit, and its working just fine.

Thought I'd share that.

Hey I just started working with bioreactors and generators, I was transferring energy to a redstone energy cell and then my tekkit crashed. Here's a crash report:

Should just be a simple matter of deleting the jdk1.7.0_23.jdk file:

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk

java -version

That should remove Java 7, and confirm that Java 6 is now reporting in as the system default (assuming it was installed before Java 7 was).

Thank you Dash, I did the "java -version" and it said I had 1.6, so I guess everything should work fine now :D
