Video driver problem on upgrade to Hardy

[Paolo]

Good morning!
Current situation:
Managed to get back to the correct 1920x1200 resolution. But everything running
*very* slowly.

Thanks. Now I have it. But I cannot get it to change to the hardware I have. It 
crashed, so I have put in a bug:
https://bugs.launchpad.net/ubuntu/+source/displayconfig-gtk/+bug/221764

This reports:

E: Couldn't find package x11-server-utils

I already have:

Section "Screen"
	Identifier	"Default Screen"
	Device		"Configured Video Device"
	Monitor		"Generic Monitor"
	Defaultdepth	24
	SubSection "Display"
		Depth	24

		Modes		"1920x1200 at 60"	"1680x1050 at 60"	"1600x1024 at 60"	"1440x900 at 60" 
"1280x800 at 60"	"1280x720 at 60"	"1280x768 at 60"	"800x600 at 60"	"800x600 at 56"

By the way, yesterday I tried to install the Feisty file
xserver-xorg-video-ati_6.6.3-2ubuntu6_i386.deb (having uninstalled the newer 
one), but the system refused to install it, saying that it was old package.
