[Original Report]
Binary package hint: xorg
Hi, well this is my second time, trying to migrate to Jaunty 9.04. But still
having the same problem, the IBM Thinkpad T40 - Video ATI Technologies Inc
Radeon Mobility M7 LW [Radeon Mobility 7500] is not working properly, in fact
it's very slow, and use the Xorg process between 20% to 99% of my CPU.
In Intrepid 8.10 it works perfectly, now I will attach some files than may be
can help.
Please let me know how can I help to fix it.
<later>
Well. Finally I found the way to make works it.
I did change the /etc/X11/xorg.conf file, Now it's working fine
Let me show you: with this configuration the system is working like with
Intrepid.
