Hvala,
To bi trebalo da reši problem, čim probam javljam.
On some ATI GPU system starts with a black screen
Solution: add “nomodeset” to kernel command line, boot/install the system, then install proprietary fglrx drivers, enable it and remove nomodeset from cmdline. – If you receive any graphical issues with ATI card you can always try proprietary fglrx driver.
