Driver "fglrx", 3D acceleration and Ati Radeon 7500

[Guillermo Latorre]

¡Hello everyone!

I use Ubuntu Dapper, recently upgraded, on my Thinkpad T41 laptop. 
I was using Breezy and no problems with 3D acceleration on my ATI Radeon
7500 Mobility. When I installed Ubuntu, the card was succesfully
installed by
Ubuntu during the system installation process. 

That systema was Breezy. Now I have upgraded to Ubuntu Dapper and I have
lost the 3D acceleration. 

I have read many manuals and "ATI and fglrx for 3D" How-to's  but I
can't get it working.
The problem is I can't start a X session with "fglrx" driver
in /etc/X11/xorg.conf, but it works prefect with "ati" and "radeon"
drivers. The system tries to start X but it can't, and get a "no screens
found" error.
No screens found!!


I have installed linux-restricted-modules-2.6.15-15-686,
xserver-xorg-driver-ati and xorg-driver-fglrx.

When I try to insert the fglrx module, I get:

root at Will:/home/guille # modprobe fglrx
FATAL: Error inserting fglrx (/lib/modules/2.6.15-15-686/misc/fglrx.ko):
No such device

I attach my /etc/X11/xorg.conf file and the /var/log/Xorg.0.log that I
get when I try to start gdm with the "Driver "fglrx"" activated.


It is strange, because when I try to start a X session with "fglrx" it
causes an error "Device not found. No screens found", but then I change
the driver to "ati" and watching the /var/log/Xorg.0.log file I don't
see any "screen error", only errors or something about the Synaptic
Touchpad...

Is that the Xorg log file I need (/var/log/Xorg.0.log) to see what is
happening and what are the errors?


Can you help me?  

Thank you very much,

Guille
