NVIDIA and 24-bit color
Svein Hamnes Aaberge
support 24-bit color. When I enter YAST/Sax2 I get 3-D acceleration to
work if I choose 16-bit color. If I choose 24-bit collor the 3D gets
disabled (even though I choosed to be enabled). What's the reason for tis
and is it possible to use 24-bit color and 3D-acceleration. I have tried
on 3 computers with different graphic cards and it's the same for all of
them. All of the cards are new enough to support the resolution and color
I choose.
Thanks for your replies.

This is goofy, but it really is working under 24bit mode, despite the claims
to the contrary. Try actually choosing to disable it and running 'glxgears'
and then enabling it (despite claims contrary) and running it. Your
framerate is far higher, and evidence that hardware acceleration is working
and enabled. You could also try running Tux Racer or a GL screensaver. If
there is no jerking in the animation, you've got hardware 3D.

I just tried this and found that at 16bit no 3D my frame rate was 73
At 24bit 3D not indicating on but was selected frame rate is 63
So that blows the higher FR theory out of the water
Also saw no difference in GL screen savers themselves
I wanted to try this glxgears and Tux Racer but haven't a clue what
those are.

Do you have an nVidia card and the actual nVidia (not SuSE provided) drivers
installed? The SuSE downloaded driver through YaST does not have 3D
acceleration. You must get the ones from nVidia's site.

Correct on the Yast nvidia install. Does this have to be removed
prior to installing the one from nvidia site?

The strange thing was that it was impossible to disable it in Yast, then I
got a message that NVIDIA drivers had 3D-acceleration and if I didn't want
it I had to deinstall the driver.

It's true, I could use Tuxracer with 24-bit color.
The strange thing was the messages under glxgears:
On 16-bit color I got around 950.000FPS
On 24-bit color I got around 600.000FPS
The wheel went very slow and a little bit jerky on 24-bit.
What does this mean and is there some other settings I should change?
(Hz for the monitor i.e.)
Thank you for your reply.
Svein.

I beg to differ here but I use the Yast installed driver from Suse for my
Gforce FX5600 and it works perfect with 3D, ET, UT2003, glxears, 3Ddiag all
have 3D, I have just finished a 3 hour session on ET, and my 3Ddiag gives:-

All done with antialias set at 2, anisotropic at 2, sideband enabled, and fast

Readings would be a bit higher as I have some other stuff running at the same

No, just download the ones from nVidia't site and follow the instructions.
You must get out of X completely and install from the commandline.
Hawkeye
following instructions someone else relieved in another post regarding
this subject and I assume this is what I will need to do.
I will assume you have logged into KDE:
The way I usually install these drivers is to press ctrl, alt and F3
at the
same time. You should get a black screen with a prompt on it. Type
root and
press the return (enter) button. Enter the root password and press
return.
Now type:
/etc/init.d/xdm stop
This stops the X-window system under Suse. You should check that xdm
is in
that directory. If you are comming from windows, the directories are
separted with / and not with \ under linux.
Press ctrl, alt and F3 again to get your screen back where you were
working.
Now sou can type
sh NVIDIA-Linux--x86-1.0-4496-pkg2.run
As far as I remember there are a couple of questions to answer that
may need
scrolling down the page.
Now restart the X-windows with
/etc/init.d/xdm start
And a login screen should appear.

Well to me it seemed that the animation was going very slow compared with
the animation with 16-bit color.
I guess what you are trying to tell is that I can use my settings with
24-bit color?
