Paolo, can you open a terminal and paste the output of:

top -d1

My guess is that the slow is related to a process that is using all of
your CPU.

BTW: I just upgraded (I wonder if that's a correct term since I went
from a non-LTS to an LTS) my favorite test system to hardy. This is the
Gutsy system that I use to "tune" *all* of my applications before using
them on my production Gutsy system. Interestingly enough most went well,
but I encountered some problems that I'll post to another thread. But,
my graphics went wonky as well - including slooowwwwww video etc.

I found that glx & xinerama were sucking up 92% of the CPU. So, I
compared to my old xorg.conf and found that the option to use the
framebuffer was missing. I added it back in:

Section "Device"
	Identifier	"Intel Corporation 82865G Integrated Graphics Controller"
	Driver		"intel"
	BusID		"PCI:0:2:0"
	Option		"UseFBDev"		"true"
EndSection

I also edited my virtual terminal (I need this because I often boot
headless and then VNC or NX into the machine) to give me a 1024x768
screen (it kept insisting on using 2048x1536):

Section "Screen"
	Identifier	"Default Screen"
	Device		"Intel Corporation 82865G Integrated Graphics Controller"
	Monitor		"CM641"
	Defaultdepth	24
	SubSection "Display"
		Depth	24
		Virtual	1280	1024

rebooted, and I'm back to normal (mostly) again.

I've no idea if any of the above will help with your situation, but the
output of 'top -d1' should provide some hints.
