I am having problems with my X31 IBM Thinkpad, and think it may be this
bug. (I was referred here from this thread:

http://ubuntuforums.org/showthread.php?p=8416481#post8416481 )

My xorg.conf file is copied at the end of this post, and things work as
they should sometimes. If you turn desktop effects off, re-login, and
turn them on again then all is fine and the machine works as it should.
However, if you logout and login again then you get a series of lines
along the top of the screen, which get progressively worse. Turning
desktop effects off and on again re-sets it, but it then goes bad again
next time you reboot. Forgive me for saying this, but this would imply
that it can work, but something is reset when the machine is rebooted
which causes this problem - non?

ALSO, whenever the green lines appear (as described above), I find
myself unable to select things which are placed on my desktop. Is this a
known facet of this problem?


Oli. 

P.S. My xorg.conf file is thus:

Section "Device"
	Identifier 	"Radeon7500"
	Driver 		"ati"
	BusID 		"PCI:1:0:0"
EndSection 

Section "Device"
	Identifier	"Configured Video Device"
	Option		"AGPMode"		"4"        # optional
	Option		"AGPSize"		"32"      # optional
	Option		"DRI"			"true"    # imprtant
	Option		"DRI2"			"false"  # important
	Option 		"RenderAccel" 		"true"
	Option		"AccelMethod" 		"XAA"
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
