I recently installed Ubuntu 12.04 LTS (dual boot win 8) via live usb created using pendrive linux. I have a sony vaio multi-touch screen with nvidia geforce CUDA. You can check the specifications here : http://www.sony.co.uk/product/vaio-j-series/vpcj11m1e-b
After successful installation, it shows the boot menu (purple screen) and upon selecting ubuntu, it shows a black screen and nothing happens.
I tried the recovery mode and chose failsafeX option, the next screen said that "you are running on low graphics" and wont go any further.
I upgraded grub using root option and the very same problem persists.
i tried the very same version of ubuntu without installing and the behaviour wont change.
Do i have to find another iso file that would support the hardware of my system or is there a fix available?
Kindly help me out....i am really struggling with this OS but i want to make it work
