I'm a super-rookie here (heavy on the rookie and light on the super) but maybe this might help one of the smart guys help you.

I just got a new server and installed RHES 4 on it. The hardware is a Dell 2850 server that has onboard ATi graphics. (In my case is a 7000 series Radeon I believe.)
When X would start Gnome would seem to lock up and would sometimes load but would then be very very slow. Remote web and SSH connections were also slow or would often timeout.
Running top showed me that a gdm(?) and X process seemed to think they needed all the CPU and a great chunk of the memory.
I called RedHat for a bit of help and according to the the Engineer I got there is/was known issues with some of the ATi drivers. We set the machine to boot in runlevel 3 and then went into xorg.conf tweaked the config.

In my case this is what worked:
/etc/X11/xorg.conf
I commented out "dri" module and "DRI" section towards the bottom of the file.

My understanding is that this DIABLED some of the 3D functions but since this was a webserver I didn't really care. I just needed my GUI back.
I suppose it would be easy enough to test this fix. It would at least let you load X afterwards so that you could go get a newer driver from ATi if it indeed seemed to help.

I know this may not be exactly the same thing but the RH folks seemed to know exactly what the problem was and as far as I can tell your card can run some the same ATi installer and in both my install and yours they were clean and current distributions

Good Luck!

You shouldn't be running a GUI on the server in the
first place, mate ;}

Oh...now you tell me!
I got dual 3.2G Xeons and loads of RAM just to support my GUI habbit.

It's part of my baby steps...

I wouldn't think so (if there were problems it most likely
wouldn't let you turn it on). Try:
hdparm -d 1 /dev/hda

Damn! I tried it and it said:
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Permission denied
using_dma = 0 (off)


So if I can't turn dma on it will be too slow to use. Does this mean I can't use linux?

That means that the current kernel you're using doesn't
support that chipset. Try getting a more recent one.

What does uname -a say?

Linux mepis1 2.6.10 #1 Wed Feb 23 16:54:53 EST 2005 i686 GNU/Linux


How do I upgrade the kernel? Synaptic?

EDIT:: Looking at synaptic, the only kernel available is 2.6.11, surely a small upgrade like that won't make a difference, will it?

It might... but the actually current kernel is 2.6.15.1

And so much for the benefits of package-management systems ;}

Just grab the kernel source and compile it yourself.

I was afraid you would say that.

I'm now also having problems logging off however, X seems to fail when I log off. Would it be easier just to install another distibution? With better support for my hard drive (later kernel) and an easy graphics card setup?

Can you please recommend to me a user friendly distro which has the latest kernel? I really don't want to go about compiling my own kernel just to get it working properly.

Thanks for the help.

Quite a few distros have a reputation as being newb-friendly;
I can't tell you which one has which kernel on the current
version, though; you may want to go to distro-watch and go
through the specs.

But really, compiling a kernel isn't wizardry. You unpack
the source, copy the /boot/config-<version> to the kernel
source directory, run "make menuconfig" and check the CPU
type and model, save the config. Run make, run
"make modules_install" ... it's all well documented here for
varied distros.



Cheers,
Tink

For me, it does seem wizardry. When I tried linux before, I was compiling everything. I got errors coming at me left right and center, when I uninstalled linux and put windows back in full control, I finally stopped compiling everything.

Now I want to get back in linux, I want to have a fully working system. From the hard drive to the graphics card,once it all works smoothly then I'll start being more adventerous, I'll even start porting my c# things to mono.

Compared to apt, how many packages does mandriva have? I liked mepis because of it's package system, apt made it easy to install things without compiling things, so does mandriva have lots of ready compiled packages?

You'd be hard-pressed to find a distro with a 2.6.15 kernel. I personally use PCLinuxOS, which has a great reputation for being user friendly and working straight out of the box. Their latest released version (they call it preview .92) comes with a 2.6.12 kernel, but you could upgrade it to 2.6.13 through Synaptic quite easily (it will take about about 1 minute to download/install)
