I just installed a fresh Edubuntu 12.04.
It asked me to select which mode to enter. I selected Edubuntu "normal mode" and after that nothing appeared on the screen, but screen kept on blinking. This continued for 15 minutes.
I have AMD RADEON as graphic card.
I can, however, login to edubuntu using recovery mode and pressing "resume boot" option.
How can I resolve this problem?
