Thanks for reply cwwilson721

I've commented out

Code:

Section "Device"

    Identifier        "Standard VGA"

    VendorName        "Unknown"

    BoardName        "Unknown"

    Driver    "vga"

EndSection

and no result, it still needs ro startx twice. Do you have any idea why this happens? It used to work with kernel 2.6.14 and some older drivers (i believe 8.20.8). I guess i'll try that again.

Look's like your right

The drivers come from the kernel or from ATI/NVidia. Xorg is just the framework for a GUI. Changing Xorg throws a huge wrench into the works. Try the latest kernel, too. And make sure your chipset is enabled, etc...

Look at this post, it demonstrates why kernel updates can be a huge boost (But ATI experience can/does/will vary...lol)

Uninstalling video and re-installing w/this upgraded Xorg did restore my DRI.

BTW, everybody, thanks for the votes! Much appreciated.

Ok so I voted...now where is my paypal for doing so LOL :D

Hi.
Still can't make ati's driver work. I still need to startx twice.
But this is what i've found (more like stumbled upon).
I've messed up the kernel and reinstalled 10.2 again.
During boot process agp reports this

Code:

Linux agpgart interface v0.99 (c) Jeff Hartmann

agpgart: Maximum main memory to use for agp memory: 439M

agpgart: Detected SiS 648 chipset

agpgart: AGP aperture is 256M @ 0xa0000000

After compiling and installing kernel 2.6.14.3 with AGP and ATI as modules (no DRI) on boot agp only reports

Code:

Linux agpgart interface v0.101 (c) Dave Jones

Is this some error on loading agp?

No error. That's the normal output.

Update: Disaster, maybe not...

Had a small boo-boo happen to me last night:

I was testing fan settings in my laptop and had to go do things with the kids. By the time I got back, the hdd was too hot to be considered anything but a doorstop. Luckily, I had another identical drive, so....

Previously, I made a mirror of 'current' on my nfs server, which turned out that I needed, because the only copy of 10.2 I had left the kids turned into modern art with a screwdriver... So, I booted up a 10.0 cd, started setup, an installed 'current' from the nfs server.

Yes, dear reader, I went to the 'dark side'

The results? Well, since I did it as a coherant install (not as a willy-nilly 'upgrade'), everything seemd to be working ok.

xorg is now 6.9, kde 3.5, etc. No issues so far.

DRI? OK, here is a excerpt from a previous post using 2.6.15 and 6.8:

Code:

root@toaster:~# glxgears

10365 frames in 5.0 seconds = 2073.000 FPS

12701 frames in 5.0 seconds = 2540.200 FPS

12712 frames in 5.0 seconds = 2542.400 FPS

12496 frames in 5.0 seconds = 2499.200 FPS

12536 frames in 5.0 seconds = 2507.200 FPS

12668 frames in 5.0 seconds = 2533.600 FPS

Which, since at the beginning of this thread, I was happy with 750fps.

Now?

Code:

carl@toaster:~$ glxgears

17878 frames in 5.0 seconds = 3575.517 FPS

19251 frames in 5.0 seconds = 3850.047 FPS

19364 frames in 5.0 seconds = 3872.777 FPS

19350 frames in 5.0 seconds = 3869.981 FPS

19401 frames in 5.0 seconds = 3880.005 FPS

19370 frames in 5.0 seconds = 3873.861 FPS



carl@toaster:~$

Yes. I would say it is a bit snappier.

Now, I have to do alot of tweaking, getting bookmarks, etc.

Have fun, all

WOWOWOWOWOWOWO! Holy Cow, That's insane FPS jump!

I wish:
1. I knew how to make a mirror of current.
2. I knew how to do NFS
3. I knew how to install slack over a network.
4. How to get the kids to stop messing up my stuff LOL :D

I can't wait for Slack 11. Nice job.

Send me an email, fogie, to my yahoo account (My other server is down while I switch server software), I'll help walk you through doing that stuff

Hey all.
Great news, finally i've got it. ATI's driver finally is working out. :p :p

Kernel 2.6.14.7
Ati driver 8.24.8

Kernel (agp section) is configured like this:

Code:

CONFIG_AGP=m

CONFIG_AGP_ATI=m

CONFIG_AGP_SIS=m



CONFIG_DRM=m

CONFIG_DRM_RADEON=m

CONFIG_DRM_SIS=m

Installed ati's driver, rebooted, used some old xorg.conf i had as a backup and now it works.
No need to startx twice, glxgears gives 3000+ FPS
Could this be because of the SiS on agp report cwwilson? I've only used agp/dri and ati as modules. Added SiS and it's working.

Thanks all of you for your time and effort.

By the way nice going last night cwwilson

Now that is interesting...

Hey I just got my nvidia card working on my laptop using the nvidia binary on the site. I tried it twice before when i first installed slack but for some reason it destroyed X11. About 5 installs later, now that I am happy with my install (i have sound working, along with cpu frequency stepping) I figured I might as well try again.

It worked like a charm this time, the only thing I did diffrently as far as the binary goes, was saying not to look for it on the website. I don't know how much of a diffrence that could make but thats what I did.

Also I eliminated about 5 steps I was doing while compiling my custom kernel after install. The steps involving making modules and installing them. I found they were destroying my alsa. Apparently they screw up nvidia drivers too? I'm not sure of the details obviously but now I have 3d!

Just a few questions. Now that I can run GL what can I do besides games and nice screen savers? Is there ways to enhance regular old computer using? Like REAL transparency for windows instead of the "fake" kind used for Aterm? Does using the nvidia card really take that much work load off of my CPU?

I am sure I have more questions but I can't think of any right now. Thanks for making this post, it gave me the courage to try again where I failed before.

I think it states EXACTLY that in the first post....
