I also have an old Dell latitude laptop with a 1GHz Celeron and 512 MB
ram with ATI Technologies Inc Radeon Mobility M6 LY video and with a
clean install of 32 bit karmic, I could not run system-monitor.  It
would open a window with random horizontal lines.  Also the GL
screensavers were very slow and the cosmos screen saver also exhibited
the random horizontal lines with no visible image.

glxgears showed a frame rate of 1500fps.  I know it's not a benchmarking
program...

I created an xorg.conf and this is what is in it:

Section "Device"
        Identifier      "ATI Technologies Inc Radeon Mobility M6 LY"
        Driver          "ati"
        BusID           "PCI:1:0:0"
        Option          "AGPMode" "4"
        Option          "AGPSize" "64" # default: 8
        Option          "RingSize" "8"
        Option          "BufferSize" "2"
        Option          "EnablePageFlip" "True"
        Option          "EnableDepthMoves" "True"
	Option		"SWcursor" "off"  #Faster than default (on)
	Option		"AccelMethod" "EXA"   #or XAA, which is the default and may be more stable
	Option		"DynamicClocks" "on"
	Option		"BIOSHotkeys" "on"
        Option          "RenderAccel" "true" # Enables hardware acceleration
        Option          "DynamicClocks" "on" # Adds clock scalability / power management for the video card
EndSection

After restarting x and also after trying a reboot, I still have reliable
suspend/resume, all the video artifact has vanished, system-monitor
works properly GL screensavers run pretty smoothly and glxgears now
shows 2400fps.

I do notice if I have more than 1 window open, there is a little
sluggishness if you try to move them, but I'm not sure if that was there
before.
