ATI driver with Fedora 7 : compatibility problem

[erjou]

Hi,

I'm new on this forum (and also quite new to Linux).

I have a problem with my display and I looking for help.

My problem = for a particular application, ANSYS-CFX software, the screen looks fuzzy. There are extra lines everywhere. I can't work.
For everything else, it's Ok. But I want this application to work properly.

Is there some other driver that can effectively replace the ATI driver ?
Any Linux default driver ?
My /etc/X11/xorg.conf file has a line with

Section "Device"
Identifier "Videocard0"
Driver "fglrx"
Option "OpenGLOverlay" "off"
Option "VideoOverlay" "on"
EndSection

I saw other people running with radeon replacing fglrx and it works. How can I do that ?

Here are some of my systems info
--------------------------------------
Laptop : IBM ThinkPad T60
Linux Fedora 7
graphic card : ATI X1400

driver = fglrx 8.40.4

Installation with rpm
> rpm -qa | grep -i xorg-x11-drv
> xorg-x11-drv-fglrx-8.40.4-2.lvn7

I found the solution (with some help) :

Modify the file /etc/X11/xorg-conf to the following :

Before
-----------------------------------
Section "ServerFlags"
Option "AIGLX" "on"
EndSection

Section "Extensions"
Option "Composite" "Enable"
EndSection
-----------------------------------

After modifications : -----------------------------------
Section "ServerFlags"
Option "AIGLX" "off"
EndSection

Section "Extensions"
Option "Composite" "Disable"
EndSection
-----------------------------------
