Hi!
I am a (un)lucky owner or a ASUS K56CB (notebook) with Windows 8 pre-installed. I have burnt a Live CD and I can boot from it but when I press "Try Ubuntu" or "Install Ubuntu" I get a steady black screen. I have tried replacing (note: replacing) quiet splash with nomodeset. It did not work. I think the graphics card is the problem, and it is a Nvidia Geforce 740m. In the BIOS/Setup there is no option to switch off Secure Boot, only the "Secure Boot Control", which I don't know what it is. Lastly, I wish to dual boot Windows 8 and Ubuntu 13.04, so a step by step guide would be nice.

Thanks! And sorry if duped.

-Laurence

Did you use DVD or flash drive. New versions are too large for CD and will not work correctly.
Does your system have dual video? And can you set which is used in UEFI/BIOS?
Normally with nVidia nomodeset will get you into low quality video mode until you install nVidia drivers. But Intel may need different boot parameters.

Does your system have dual video? And can you set which is used in UEFI/BIOS? I have "Intel HD Graphics 4000". No option in BIOS.

I have posted these before for Intel and several have said they work, but I do not know which ones for which systems.

Force Intel Video mode as boot parameter in grub menu - change to your screen size
video=1280x1024-24@60
and if that doesn't work you can try
video=VGA-1:1280x1024-24@60
i915.i915_enable_rc6=1

Asus i3 with Intel graphics,
acpi_osi=Linux
video=1280x1024-24@75 or whatever native resolution is

Some other boot options
acpi_osi=Linux acpi_backlight=vendor

For Intel graphics running slow:
sudo apt-get install mesa-utils
glxinfo | grep OpenGL | head -n3
