I'm running Debian Squeeze (6.0.4) 64-bit. My netbook has a 1280x720 display, but the graphics driver only supports 800x600 and sound doesn't work...

I haven't used Linux for a long time, but make sure you're using the lastest drivers for GPU and such.

EDIT;
If your drivers only support 800x600 but the game is trying to launch in a larger resolution, there's obviously a problem.

The game runs with the library LWJGL. There are a lot of posts about compatibility problems in the internet. If there is a solution, it is probably in these posts.

Also, you can try to start some simple LWJGL examples to see if the library runs into your computer.

Okay, according to lwjgl.org/forum/index.php?topic=2889, LWJGL has had some bugs triggering the same problem. The thread is from 2009, so it might not be exactly this bug.

However, a new build of the LWJGL has been release 3 weeks ago. I'll use it in the next release of B&D.

In this other thread https://bbs.archlinux.org/viewtopic.php?pid=987799, some people have the same problem with mincraft (in 2011).
Two solutions have been proposed:
- switching from the jre to the openjdk.
- running the game as root.

This last solution seams to work for a lot of people.

Please keep me in touch with the results of these solutions.
