Datasheet

You can now try to run X again with

FRAMEBUFFER=/dev/fb1 startx

Type Control-C to quit X

If you don't ever want to have to type FRAMEBUFFER=/dev/fb1 before startx, you can make it a default state by editing

your profile file: sudo nano ~/.profile and adding

export FRAMEBUFFER=/dev/fb1

near the top and saving the file. Then reboot to reload the profile file. It will now always assume you want to use

/dev/fb1
