Cannot run examples #17

Closed ericnormand closed 14 years ago

ericnormand commented 14 years ago

Hi, I'm trying to run the examples in the 0.5.0 branch. The window opens with a black background.

I could not find out how to solve this problem.

I get this error:

mode must be non-null [Thrown class java.lang.NullPointerException]

Restarts: 0: [ABORT] Return to SLIME's top level.

This is apparently because the system in question doesn't support a 800x600 display mode. I need to make that size a hint rather than an imperative.

It will now search for the closest resolution to what is requested. This should work in 0.6.0, even though you have a weird display driver.
