Ubuntu 7.10 64bit livecd failing to boot (suspends LCD monitor)

I downloaded Ubuntu 7.10 Gutsy AMD64 version and wanted to try it out via a livecd. The intention is to either do an upgrade or perhaps do a clean install at some point, but initially I just wanted to have a look.

However, it fails me on the very first step of the way. When I try to boot from the livecd it puts my LCD monitor on suspend (or standby) and stops. This usually happens when the monitor is getting incorrect resolution, it just displays a blue notice that it's going on a standby mode and goes black (turning the yellow indicator into orange).

I tried booting by setting the resolution myself from the grub screen and I also tried safe mode and some other options, but nothing worked - always the same result.

This is extremely disappointing to be honest. The most hyped up Free OS of all times and it can't even handle an LCD screen. Note that this happened with the 64bit Feisty as well, but at least setting the resolution myself worked. Strangely enough, I've had no problems with 32bit feisty (I didn't try 32bit gutsy yet). Why the hell should be ANY difference between the two just because they've been compiled for different processors??? This is beyond me.

I think I know what needs

I think I know what needs to be done here.. The splash needs to be disabled. Apparently there are some differences in the way a 64bit distribution deals with hardware..

I didn't actually try booting the livecd yet, since I deleted the image and rewritten a CD with something else, but I did a successful upgrade of Ubuntu from Feisty to Gutsy and encountered the same problem on rebooting. I then changed the splash option to "nosplash" and booted successfully,though I didn't see anything as it was booting.. gonna try to fix that somehow..

That said, Gutsy seems quite nice overall. The best things about it are GNOME 2.20, especially its most noticeable feature; the appearances dialog that now has wallpaper, interface, theme and compiz settings all in one and the compiz which works much more flawlessly. Even playing videos in Totem now works with 3D (previously only vlc could do that). I think a time is really coming for 3D to be a perfectly normal default part of people's desktops.. stability and usability wise.

It is still best to disable it when playing 3D games though.
