I've installed Ubuntu 14.04 on a mid 2010 iMac.

When I don't set the nomodeset kernel option I'm getting a black screen. It does actually boot because I can hear the login screen sound. The screen is just black.

If I enable nomodeset I'm not getting 3D acceleration using the open-source radeon drivers.

I'm sure its this one: http://support.apple.com/kb/sp588 (I'm not at work so I can't check it). And I'm also for 75% sure it has the "ATI Radeon HD 4670". I'm at least 100% sure its a 4xxx series.

I'm booting using whatever is Ubuntu's default but I'm sure its not EFI. I'm using rEFInd and I'm sure it says 'legacy OS'. So, not EFI.

Hello there for my application I need to set the default JDK for building my packages. Normally I would execute

sudo update-alternatives --config java

But how to do something like this in Launchpad? Because I get the error

/build/buildd/2stream-0.0.2/build.xml:46: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "/usr/lib/jvm/java-6-openjdk-i386/jre"

It needs to build using OpenJDK 7. I did specify it as a build dependency in the control file. I even set JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64. But it didn't work.

Is there another way to make sure the whole compile session will have the JAVA_HOME environment variable. So it will be visible to every application.

UPDATE: I do have openjdk-7-jdk installed and openjdk-7-jre installed but the problem is that for some reason it defaults to openjdk-6 (which I didn't install)
