Hi all,

I have a Revo and I'm trying to get Ubuntu on to it, but I'm failing.

I've got it to now detect the USB CD/DVD drive and start the install, but after a few seconds of showing the lovely purple background the display just goes mental.

What does mental mean, you may ask. Well, quite simply, I get all the colours of the rainbow (and probably more) flickering in horizontal lines all over the display. Thus mental is the only word I can think of that is sufficient to describe it.

Can anyone suggest why this may be happening?

Note: I should add that the CD in use has been tested and works on other PC's.

Thanks.

did not know what a Revo was. Found it is Acer model.

Is this a UEFI or BIOS based system?

Either way often video issue, and nomodeset may get you into system.
What video chip/card does it have.

How to set NOMODESET and other kernel boot options in grub2 - both BIOS liveCD & grub first boot ( also UEFI with grub)
