For some reason I can't get FtB to work even though I downloaded it and launched it normally. I created my profile, picked the Unleashed pack, and it downloaded it. When it started the game it showed the FTB animation, but then just a black screen. It said liblwjgl.so might have a disabled stack guard. I tried execstack -c liblwjgl.so but it didn't do anything.

Here's the log:

And I fixed it! I had to do this first:
Code: 
export LD_LIBRARY_PATH="/opt/oracle-jdk-bin-1.7.0.40/jre/lib/amd64"

New Ubuntu user here, and I think I have the same problem. Here's my error:

I even tried the instructions at the top, and not even that worked. :/

OK, well you have to find out where Ubuntu installs Java, and do what I did just above your post. The path will likely be different for you though, because I use Gentoo, not Ubuntu. I'm afraid I don't know where Ubuntu puts Java.

Once you find that out, you'll want to make a shell script for launching FtB that exports that environment variable first. As an example, I'll call it ftb.sh. Something like this:
Code: 
#!/bin/sh
 
cd /<path-to-your-ftb-launcher>
 
export LD_LIBRARY_PATH="/<path-to-your-java>/jre/lib/amd64"
 
java -Xmx512M -Xms1G -jar FTB_Launcher.jar
 
cd -

Then you'll want to make that executable, I used:
Code: 
chmod +x ftb.sh

Then you'll just run that file, and FtB should launch and run fine.

Thanks for the feedback! I tried what you said, and unfortunately it didn't work. This is what Terminal says when I run that .sh as an executable:
Code: 
/home/matt/ftblauncher/ftb.sh: 2: cd: can't cd to /home/matt/ftblauncher/FTB_Launcher.jar

It's strange because I'm not sure why it's saying it can't cd to the path for the launcher... since... that's the path. :p

Then this is the console from FTB, although, I'm pretty sure it's just the same crap we've been seeing already:
Code:

It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Regardless, thanks for the help anyways, even though you're on Gentoo. :)

Oh., that's because you tried to cd to the jarfile. You want to cd to only the folder the launcher is in. Remove "/FTB_Launcher.jar" from the line with the cd command in the .sh file.

Oh lol. Derp on my part.
Now it boots up, but still gives an error (pretty sure the same one). I'll have to do some digging.
