Please note, you have to make sure the kernel is configured to accept the new driver module,

I think that is where you are....

check the log file for/from the radeon/fglrx install program. usually in /var/log/...(something. ati? fglrx? ..install.log)

My friend iro_number1 has been doing this lately, maybe you could ask him via pm.

Please note the dkms driver modules "Dynamic kernel module service" is designed specifically for it's simplicity of setup.

The .run files are harder to setup, but sometimes it's the only way, Mandriva has dkms, maybe not red-hat and fedora and suse, etc.

Here is a copy of what I sent to iro_number1...(yes it's quite long and only talks about the kernel...)

Quote:

Hi, here is a guide to configure and rebuild your kernel.

Based on my current kernel...
glenn@GamesBox:~$ uname -a
Linux GamesBox.GlennsPref.net 2.6.28-desktop-0.rc8.1mnb #1 SMP PREEMPT
Sun Dec 28 12:03:15 EST 2008 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 5600+ GNU/Linux

Download and install the kernel-source or kernel-headers, depending on the docs, to match your running kernel.

first, you may need to be root to start the config program, try it as user first.
other wise su to root.

su
enter password

change to the kernel source dir...

cd /usr/src/linux (is a link to the current kernel sources, if installed from .rpm)

execute the kernel make configure program

make xconfig
Open the current(installed) kernel .config file.

goto file, load. navigate to /boot/.config
(this links to your current kernel config file not the clean source.)

in General setup, Enable the Block Layer, IO Schedulers, check that CFQ is dotted as "Default I/O Scheduler".
Allow the other boxes above (on this same page)to be ticked as well. Should be already set, as default.

to find "CONFIG_SCHED_DEBUG"as mentioned in the WoW/wine
(wow with wine! you want fries with that, sir?)fix...
from here...
"Now open up the file config, search for the line "# CONFIG_SCHED_DEBUG is not set" and replace it with "CONFIG_SCHED_DEBUG=y""
as mentioned here... http://www.wowwiki.com/Troubleshooting_Wine

under Kernel hacking/Kernel debugging
select "Collect scheduler debugging info" (SCHED_DEBUG)

"If you say Y here, the /proc/sched_debug file will be provided
that can help debug the scheduler. The runtime overhead of this
option is minimal."

If it is already selected, no need to recompile the kernel.
Mine is set already. I have not changed it, default maybe "on".

What about the things we changed the other day, like read/write to ntfs?
ctrl+f (find), type in ntfs, saves time.

It is found under file systems. dos fat and nt.

drm(dri) and agp is under Device drivers/Graphics support/
check you have the sis agpgart as a loadable module (dotted is dynamic, not ticked(ticked is static))
and make sure the others are not ticked either, set as loadable module instead.

The "AMD processor (Opteron and athlon64) has it's own on-cpu GART support.
So the Sis one may not be used."

DRM, DRI...Direct Rendering Infrastructure
"Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) (DRM)

Kernel-level support for the Direct Rendering Infrastructure (DRI)
introduced in XFree86 4.0. If you say Y here, you need to select
the module that's right for your graphics card from the list below.
These modules provide support for synchronization, security, and
DMA transfers. Please see <http://dri.sourceforge.net/> for more
details. You should also select and configure AGP
(/dev/agpgart) support."

refer to fglrx config web page for more... on ati stuff.
Be carefull of the age of these docs, some things are standard now.

In brief, If you have not needed to change anything (I have not)
Then you will not benefit from a recompile.

But if you do, read on...

save the config file with the save button/icon
That should save the .config file to /usr/src/linux/somewhere.

and exit xconfig program.

to compile the kernel with the changes, type (you should still be at /usr/src/linux for this)

make all
this does... make dep && make clean bzImage modules

make modules_install

as root...
make install

reboot to get the new kernel (config) loaded.
shutdown -r now

If all of that goes through with out errors, all good.

Let me know if I can be of assistance.

Cheers, Glenn

Regards, Glenn

ps. how the kernel looks?....
