Alright, it seems a lot of people are curious about whether ATI catalyst driver 9.6 runs in F11, including me, I decided to give it another try - the first try was a failure when I tried to downgrade kernel to 18.104.22.168-170.2.68.fc10 directly. Now, the result of second try is out, it works.
That is, when you do the following steps. It is worth mentioning that there is absolutely NO guarantee that it will work in your system. If you want a stable system, I suggest a little more patience while playing with community driver, which in my opinion deserves praises, since it is getting better all the time.
My hardware specifications:
Athlon X2 7750 BE + DDR2-1066 2G x2 + Asrock 790GMH/128M + integrated graphics HD3300
OS: Fedora 11 x86_64
1) download fc10 kernel source rpm:
2) rebuild 22.214.171.124 kernel for F11
$rpmbuild --rebuild kernel-126.96.36.199-170.2.68.fc10.src.rpm
note: keep it in mind, this step may take while and require about 7G disk space
3) install new kernel and kernel-devel packages
#yum localinstall kernel-188.8.131.52-170.2.68.fc11.x86_64.rpm kernel-devel-184.108.40.206-170.2.68.fc11.x86_64
note: you need to disable gpgcheck temporarily.
4) download ATI catalyst driver
note: if you have a different chipset, choose what you need accordingly.
5) install ATI catalyst driver
6) check out xorg.conf file. If you don't have a /etc/X11/xorg.conf beforehand, I recommend create it before step 5 by:
#Xorg -configure :1
#cp ~/xorg.conf.new /etc/X11/xorg.conf
7) disable SELinux by append 'selinux=0' . Yeah, you have to do this, otherwise, at least in my box, it won't boot.
#sed -ie 's/\(kernel .*220.127.116.11-170.2.68.*\)/\1 selinux=0/' /boot/grub/grub.conf
8) reboot system, and good luck!
9) when you are tired of fglrx, or rpmfusion release fglrx rpms, you just need to do:
#yum remove kernel-18.104.22.168-170.2.68.fc11.x86_64.rpm kernel-devel-22.214.171.124-170.2.68.fc11.x86_64
then everything back on track again.
1) the alsa driver in kernel 126.96.36.199 is 1.0.17, so, if your audio card is not supported like mine, you'd better download alsa driver 1.0.20 and install it.
2) some system services may need to be manually enabled again.
3) the driver runs basically stable here, but I find the window minimize/maximize function does not work rightly. But I'm not sure whether it's a compiz problem or fglrx issue.
Ok, the difference of glxgears benchmark when using radeon or fglrx driver is quite noticable, about 330~360 fps (radeon) vs 2000~2900 fps (fglrx), although the difference of realtime performance aren't that different.
Another thing, when selinux is enabled, F11 won't boot, in my case, it hangs at system logger after auditd failed message. So, i whether it is a selinux conflict or audit daemon issue. I hope someone may give a hint here.
Yes that is a nice idea but have you ever thought of going up to the biggest guy on the subway and telling him your thoughts on this. I wonder what he might do, or would you even do it.
