So you'd want to use the VM parameter -Dorg.lwjgl.opengl.Display.allowSoftwareOpenGL=true to allow software mode.
That will only allow a fallback to the software renderer if a hardware renderer is not found (by default it will throw an exception, I think). In molzb's case, he wants to force LWJGL into thinking that there is not a hardware accelerated renderer which I don't think you can do through LWJGL.
You might be able to set the acceleration of your graphics to be none (in the control panel in Windows) assuming you aren't using Linux/Mac.
Another idea is to try a virtual machine with no hardware acceleration turned on.
Otherwise, just force your software to take the different code path.
Thanks to you both. This is leading into the right direction.
Software mode works for me, I saw it because in my applet
there was no antialiasing any more (in hardware mode there
is antialiasing).
Which leads to the question: If no hardware renderer is found,
can I just set
System.setProperty("org.lwjgl.opengl.Display.allowSoftwareOpenGL", "true")
and force software rendering?
Is there a subtle way to find out if a hardware renderer is existing
other than catching an exception?
We are making tests to run our LWJGL applet on a linux netbook
without hardware acceleration. But I am programming on Windows
and want to emulate that case.
Ok, I'm gonny try it out now.
