I was using Ubuntu 15.10, driver nvidia 358 from graphics-drivers PPA, my discrete card is GT-650M.
Some time after said update, I had some ugly poligons and horizontal lines on my notebook, and everything froze. It booted on Gallium, and I tried to reinstall Nvidia, but problem only become worse, and now every time I boot, I get a frozen blank, white or not so nice coloured screen.
Now, my objective is to do a clean reinstall.
I tried to boot Ubuntu 15.10 x64 from UEFI live usb, but the same screen appears, and it freezes. When I put nomodeset option, Ubuntu boots, but screen is so teared and distorced up that I cannot proceed with installation. Emergency and recovery mode works well. Xsafe does not. Antergos live freezes on loading Gnome, but no strange screen.
I'm on my cellphone, but I'l try to provide as much information as possible.
May any option besides nomodeset fix my screen (or force external monitor) and allow me to boot live usb (forcing Intel graphics)?
