I installed Ubuntu 10.04 and have similar "freezes" as the above posts.
The screen finishes loading and all the menus and desktop loads fine but
just as soon as I moved the mouse cursor it freezes (mouse, keyboard,
everything) and I have to press reset.
After I rebooted and selected recovery mode and then low-graphics mode I
had no freezes and no problems using any program I have installed except
(and most importantly) Blender (3D animation software). As soon as I
start Blender and move the cursor and start selecting or moving objects
in 3D space it freezes like clockwork every time. I use Blender a lot so
I can't use Ubuntu without it. strangely enough after rebooting after
using safe graphics mode it doesn't freeze again unless I use Blender
but I really don't think it is a problem with Blender.
I suspect this is a graphics problem as well as a hardware recognition /
hardware support problem.
I have the same problem when I install Ubuntu 9.10 on this PC so this
can't be a new bug because everything worked fine in Ubuntu 9.04 on this
PC. From Ubuntu 9.10 onwards it is totally hopeless.
My PC that freezes with ubuntu 10.04 and 9.10 is my newer PC, a Core2
Duo (several years old but much faster and newer than my other one). I
don't have a 3D graphics card for this PC but it does seem to have a
built in 3D chip on the motherboard that doesn't seem to do much or
increase performance much.
I have used Ubuntu 10.04 on my other much older PC (Pentium 4 1.8 ghz PC
with 250mb Nvidia geforce 5200 graphics card and 1000 MB ram memory) and
it works without freezing on this PC but I was hoping to be able to get
Ubuntu 10.04 working smoothly on my faster PC.
