I'm trying to speed up NetBeans on Ubuntu.

I was reading about that on http://performance.netbeans.org/howto/jvmswitches/

I get this error:

sh /home/umpirsky/Applications/netbeans-7.2rc1/bin/netbeans -J-Xverify:none -J-Xmx384m -Dsun.java2d.opengl=true

Unknown option -Dsun.java2d.opengl=true

Should I use some special version of Java?

As the name sun.java2d... indicates, this is (or was)an option for the Sun/Oracle JVM, and is probably not supported by Ubuntu's default OpenJDK JVM.

You would have to install the Oracle JDK/JRE to see if that option works. It may be easier to first understand how it helps speed Netbeans up and whether you really need it.
