Refactoring of Jnode


I am Aziz a graduate student from university of Maryland at Baltimore county.
I an new in this forum but pretty much interested in your project.

Also i would like to learn new things pertaining to operating systems if i get affiliated to this project.

Could anyone guide me as where to start from.

Jnode GUI problem

When I boot Jnode from CD ("Default" grub selection), it's OK (text-mode works fine), but when I run "startawt", my screen is black and nothing happends. When I boot in VESA (grub option) and start "startawt", i see only black screen and mouse cursor, no windows, no desktop.
My PC:
- graphic: nVidia GeForce 4 MX
- CPU: Intel Celeron 32bit 2GHz
- RAM: 512MB
- PS/2 mouse & keyboard
Do you have any ideas why is doesn't working?
