Default Re: slow repainting textures but fast with 3D

ANybody know why this might be?
I guess you compiled it in i386 instruction set which is slow.
Try compiled it in i686 instruction set which is much faster.
May by try Athlon or pentimumIII specific instruction set build,
which is further faster.

i686 instruction set build :
rpmbuild --target i686 --rebuild NVIDIA_kernel-1.0-4191.src.rpm

For Athlons and Durons instruction set build
(I read from other people and have no that CPU try this) :
change to root
edit /usr/lib/rpm/rpmrc
found optflags and change it to :

optflags: athlon -O3 -march=athlon -funroll-loops -fomit-frame-pointer -fforce-mem -fforce-addr -finline-functions -malign-functions=4 -mpreferred-stack-boundary=2

then execute
rpmbuild --target athlon --rebuild NVIDIA_kernel-1.0-4191.src.rpm

For pentiumIII instruction set build
(I read from other people and tried this) :
change to root
edit /usr/lib/rpm/rpmrc
found optflags and change it to :

optflags: i686 -O3 -march=pentium3 -mcpu=pentium3 -mmmx -msse -funroll-loops -fexpensive-optimizations

then execute
rpmbuild --target i686 --rebuild NVIDIA_kernel-1.0-4191.src.rpm

For pentiumII instruction set build
(I read from other people and if I have so many time, I may try this) :
change to root
edit /usr/lib/rpm/rpmrc
found optflags and change it to :

optflags: i686 -O3 -march=pentium2 -mcpu=pentium2 -mmmxon

then execute
rpmbuild --target i686 --rebuild NVIDIA_kernel-1.0-4191.src.rpm


The about flag can be found in gcc manual.
O3 stand for Optimize yet more (highest at this stage)
your can also edit :
~/.rpmrc only one user (e.g. /home/peter/.rpmrc for peter only)
/etc/rpmrc for all user
/usr/lib/rpm/rpmrc redhat 8.0 use it for all user

Regards,
Keung

So I installed the new kernel again, and restarted, then everything worked (i.e. the source built).

I am using a Geforce4 TI 4200, but I have the Geforce4 Generic selected. Also the 3d acceleration box is grayed out.

My question is: why would the performance be worse (my original driver was "vesa"), and should I be using the "Geforce4 Generic"?
Thanks,
Kernel is found security hole, so a fixed bug version is released thought up2date.

The nvidia driver cannot select 3d acceleration, In fact it has acceleration all the time.

The kernel build in driver is not optimize for nvidia card. It can be
use if you don't care lost the power of you nvidia card.
Nvidia driver need some patience to build it.

Default Re: new Install RH 8.0 and Nvidia

Quick question, I see some very helpful posts and it looks like I can do this. I have a freshly installed RH 8.0 on an Athalon box. I have a GeForce 420mx card w/64 meg DDR. My card was auto detected, but of course nothing worked. Now, to get X to run I picked cards at random until I got one that would run X (I believe I settled on a TNT Driver). My question will this cause a problem when I try and install the "correct" Nvidia driver. and if so, how do I install the driver when I cant get X to run ?
thanks for the help.

Next task is to get sound !
Please execute the below to let me know which kernel you are using :
uname -r

If you are fresh installed RH8.0 and not willing to update kernel,
you can found driver at nvidia official site :
http://www.nvidia.com/view.asp?IO=li..._ia32_1.0-4191

But If you updated kernel, please rebuild the src.rpm or tar.gz package to make a kernel suitable driver.

Building driver need extra patience.
You need install required compiling tool and kernel source,
which is hard to newbie.

In fact I am a newbie too with a little bit of experience.

Regards,
Keung

Default got it working!!

Thanks for the advice. I actually installed the 3123 driver, and everything including twinview seems to be functioning great now. I would have tried the i686 build, but I read another forum first that said the 3123 driver was better at 2d than the 4191 driver, so I just went with that.
Thanks

Default X Freezes after successful install

I followed the directions exactly and both rpms install successfully i've edited my XF86Config file and when X loads the nvidia splash screen comes up, it goes black comes up with the login screen and hard freezes, no mouse, no keyboard, nothing, only way to fix it is to revert to old drivers. here's a snippet of my XF86Config

.........
Section "Module"
Load "dbe"
Load "extmod"
Load "fbdevhw"
Load "glx"
Load "record"
Load "freetype"
Load "type1"
EndSection
............
Section "Device"
# no known options
Identifier "NVIDIA GeForce 2 MX (generic)"
Driver "nvidia"
VendorName "NVIDIA GeForce 2 MX (generic)"
BoardName "NVIDIA GeForce 2 MX (generic)"

#BusID
EndSection

any ideas?

argg... after working my ass off to try and get my nforce board to work with 7.3, i decided to shoot for 8.0... everything went fine until i went to go edit my XF86Config file in the /etc/X11 directory... it wasnt even there!! so where is it? i tried to reinstall XF86 just in case it wasnt installed, but it told me it already was...

btw, with no pico in RH8, which is the best program to use? how can i edit the file? (pertaining to if i find it...)

**edit ** after reading some other pots on here, i realized i hadnt installed my recompiled src rpms, but after doing so, still no config file **edit**

my other question is, i try to start x, and it gives me the no screens found error. if i get the config file squared away, is this most likely the problem and will this work now???

Default Question Answered

This question was be answered in the REDHAT 8.0 nforce install thread... just for other people in the future to find the answer...

.02 answer...

run redhat-config-XFree86 first before XF86Config file is generated... use the --set-driver nvidia tag to the config command... then edit XF86Config file as per usual... use vim... everyone else does

Unhappy

Hey ppl

Thanks for all the advice so far in this thread, it has helped me a lot. I do however still have one problem...

After installing all the rpm's (compiled from source rpms) etc and modifying the XF86Config file, I try to run X (xinit, startx)... to no avail. This is the error message that I recieve :

LoadModule: Module nvidia does not have a nvidiaModuleData data object.

Consequently I can't run X as it can't load the driver :P

I'm hoping (optimist that I am) that is a relatively minor software problem and that I can just quickly go update some file somewhere to fix it..

Any advice/insight would be much valued!!

thanks to all who answered my questions... i finally got it up and running...

however, now, im a little concerned about updating the system kernel.

from what i understand, all i need to do is upate the kernel, then rebuild the rpms from the source rpms and reinstall the nvidia kernel and GLX drivers, right? what about the nforce rpm?

once again, thanks to all...

Thumbs up ATT Keung RE:Nvidia Driver

I couldn't figure out how to reply to you.
That command gives me the output :
2.4.18-14

BTW I got X to run fine by picking another NVidia card during the install. But since I want to LEARN Linux, I want to try this

2.4.18-14 is the orginal kernel version of RedHat 8.0 CD.
you can found driver at nvidia official site :
http://www.nvidia.com/view.asp?IO=l...y_ia32_1.0-4191

Because the kernel source package included all the driver. Once kernel rebuild, all driver need rebuild.

A bug was found and fixed, new version has rebuild (released),
driver is needed a new rebuild.
The RH 8.0 kernel is build with module.
kernel and driver module can rebuild separately.

I learn rebuild kernel from these site. :
http://www.linuxfocus.org/English/Ju...ticle209.shtml
http://en.tldp.org/HOWTO/Kernel-HOWTO-2.html

May be the driver not support you VGA card?
What card you tried failed.
In fact I have not idea of different model of VGA card. I think you can check VGA card isn't support on offical site.

Hope it answer you question.
Keung

You are right !
I think the offical site people is busy.
They are working new driver.
May be they are not using redhat distribution of Linux.
They are not notice a security bug fixed kernel released.
