I created a bootable USB drive with Ubuntu 13.04 image. I managed to boot my Samsung ATIV. the GUI, mouse and keyboard work perfectly, and the installation works without problems.
When I boot the system for the first time, however, once the GUI of Ubuntu loads, neither the keyboard nor the trackpad work. The system is therefore rendered useless.
The keyboard works OK in Grub.
Any pointers on how to troubleshoot this problem?
