I've just installed Ubuntu 13.04 x64 on my HP 1000 1220LA laptop. After dealing somewhat successfully with the UEFI boot sector with refind www.rodsbooks.com/refind/, I've got a dual system with Windows 8 preinstalled. However, when starting Ubuntu a blank screen appears and no tty terminal appears. I've performed software updates, but I only can access the tty terminals via Ubuntu Recovery option on the GRUB menu, so I'm working with a console system.
Here's the Xorg Error Log: log
Any suggestion, please?
