Hello all
After closing a program, which releases priamry and super DFB
interface, I'm not able to open the fb again. Why could that be?
Source code attached.
Here is end of strace output from first run (releasing)...

Here is error, which I get when running again (have to reboot to make it run).

Don't know why it tries to open tty5 ... :-(
Any ideas?
