Zaurus Drivers

qtopia driver

The qtopia driver recognizes these additional environment variables:

SDL_FBDEV Sets the framebuffer device to use. Defaults to /dev/fb0
USER determins which QtEmbedded-0.spec to read rotation info from. Where: /tmp/qtembedded-(USER)
SDL_FB_SIZE Limits framebuffer size?
SDL_QT_ROTATION_ENV_NAME supposedly affects how the screen is rotated
SDL_FB_DIRECT Not sure exactly what this does. Setting it greatly enhanced performance for some apps, seems to not work at all for others.
SDL_QT_INVERT_ROTATION_ENV_NAME Not sure what this does

bvdd driver

The bvdd driver recognizes these additional environment variables:

SDL_BVDDDEV points to the bvdd device file. Defaults to /dev/bvdd
USER determins which QtEmbedded-0.spec to read rotation info from. Where: /tmp/qtembedded-(USER)
SDL_QT_FORCE_QVGA unsure what this does
SDL_QT_ROTATION_ENV_NAME supposedly affects how the screen is rotated
