Hello,
 
I downloaded the git repository  git clone git://github.com/genodelabs/genode.git
and configuring the
    foc_x86_64 configuration.
 
Running it with 
     make run/demo
it didn't work, because the fb_drv ist missing in the bin - directory.
 
Comparing the version with the genode_13.05 - Snapshot, I find out, that 
cd os/src/drivers/framebuffer/
 cp -r ~/genode-13.05/os/src/drivers/framebuffer/vesa/ .
 
solves the problem and the demo runs as expected.
 
Why is the component is not in the git-repository ?
