Hi
I'm running Fedora 4 and have updated it with "yum update" and it completed the update OK.
I had problem installing "fglrx_4_3_0-8.16.20-1.i386.rpm" form ATI for it was asking for libstd++c.so.5, that is now installed. Now I get this:

[root@ros ~]# yum install /root/Desktop/Downloads/ATI/fglrx_4_3_0-8.16.20-1.i386.rpm

root@ros ~]# rpm -i /root/Desktop/Downloads/ATI/fglrx_4_3_0-8.16.20-1.i386.rpm
file /usr/X11R6/lib/libGL.so.1.2 from install of fglrx_4_3_0-8.16.20-1 conflicts with file from package xorg-x11-Mesa-libGL-6.8.2-37.FC4.49.2

I installed the driver first, but open gl was not working, and I read in other forums that .rpm package should be installed first. Am I doing it the right way, and if so what's the next step?!
thanks

ATI drivers must be installed with --force option

$rpm -Uhv --force /root/Desktop/Downloads/ATI/fglrx_4_3_0-8.16.20-1.i386.rpm

should install.

Thanks a lot. You saved my day!

OK, it worked, and everything installed, but still no 3D acc. So I reinstalled and updated Fedora and then libstdc++.so.5, fglrx for X.org and than ATI drivers and ran fglrxconfig. I lost my resolution for 1280x960 and got nothing in return! I past here the original config file and the one after running fglrxconfig. Can somebody guide me through?! I just wonder how is Linux going to be popular if installing a simple driver has to be so complicated!
I delete the comments and other non-graphic parts to make it shorter!

Thanks

Just use yum to install.

dont forget you need the kernel module..


yum makes it very simple

Ok, just installed Mandriva 2005, rpm ATI, changed radeon to fglrx, reboot, and glxgears=12000+.
Thanks
