HOWTO: Get 3D acceleration with Voodoo3 using the tdfx driver

[Newmark]

Hi
You posted:
>Then I had all the dependencies and code. The diff file showed the change
>that I did not want, so I went into the original Debian code and did the standard
.>/configure, make, sudo make install.

What code?
What line?
Where did you get it?

Sorry if I did not see it, but I'm a bit of a newbie to all this, so...

Thx in advance

[cbrinegar]

It is a bit confusing. The downloaded ubuntu package has the change in a diff file. Here is a copy of the patch so you can see the code I'm talking about. I recompiled the code without this patch being applied.


See: 01_tdfx_disable_dri_on_16mb_with_highres.diff

Thank you so much for the great guide! I got this working on my PC, thanks to you.

I'd just like to confirm: you applied no patch at all, or you patched but omitted that specific segment of the .diff file?

Hi.

I recently installed Ubuntu in an old PC with a Voodoo3. Everything is OK, the xorg logfile shows the line "(II) TDFX(0): Direct rendering enabled", but when I run glxinfo it says it's not enabled. I've set the DefaultDepth to 16 and max resolution to 1024x768.

Googling arround, i found that your card needs to have bus mastering enabled in orther for the DRI driver to work, but doing a "setpci -s 01:05.0 4.w", it returns 0003, which means it's not enabled. I tried doing a "setpci -s 01:05.0 4.w=0007" to force the bus mastering on, but it returns "pcilib: Cannot open /sys/bus/pci/devices/0000:01:05.0/config" and the 0003 value is not changed.

I really don't know if the bus mastering thingy is really the problem, as far as it is an AGP card. Btw, I'd like to know if there's any other option to set the bus mastering on through linux (my BIOS does not show the option) or if you know what's the problem here.

Thank you.

Hi all,
I installed mesa and liglide3 and now I've exactly the same problem as gonssal on the same hardware.

Any help? Thank you!

i have the same problem as well but i run a nvidia 6200

[QUOTE=cbrinegar;2681105]Okay, so I am now using my Voodoo3 3000 AGP video card (16 MB of memory) at 1600x1200 with DRI (hardware acceleration) as I wanted. I found that some Ubuntu developers decided to try to protect us from not having enough memory to use fancy textures at this resolution and limited the DRI to lower resolutions. I wanted the DRI at this resolution, because the 2-D acceleration makes my old system much more responsive (PII 400 MHz --- don't laugh).

I'd like to THANK to cbrinegar, first of all.
This procedure WORKS.
I also use an AMD @ 750MHZ with a Voodoo 3 3000 video card with 16Megs of video memory (it seems we are still many ! )

To start with, be aware that what cbrinegar describes here is not 'magic'. We are 'squeezing' the video card's resources so, due to the lack of enough video memory, you will notice things like flickering when rendering 3D at fullscreen. For example, if you run the OpenGL screensaver that come with Ubuntu, in fullscreen mode, you will notice this flickering in most of them, and a heavy one in the most complex of them.
So, what is done here is just to be able to use 2D acceleration whenever it is useful, and to have ocasional 3D acceleration, preferably not at fullscreen if exceeding 1024x768 pix.

I just will try to explain further a couple of the steps for nOObs like me to have it easier.
-Begin cbrinegar's procedure. At the point where he/she says to 'add Glade', I did this: used Synaptic to look for 'glade-3'. Right clicking on it, I installed just the packages listed under 'recommended for installation', which in my case implied only the installation of 'autoconf' and 'automake 1.4'. I didn't install 'glade-3' itself.
-Jump to the point where he/she types: 'sudo apt-get...'. Once I completed those two operations, I found a directory called 'xserver-xorg-video-tdfx-1.3.0' under my home directory. Inside it there is a subdir called 'debian'. Again inside it, there is a subdir called 'patches', where there is a file called '01_tdfx_disable_dri_on_16mb_with_highres.diff'. Open this file for edition. I started gedit from a console: 'sudo gedit' to have root permissions, cause this directories and files where placed with root ownership.
-Look for a sentence near the middle of the file where it says: '1024 * 768'. I replaced it with: '1600 * 1200'. If you want it, you can add an explanatory comment of what you did here for if you happen to return to read this file in the future.
- Then, I typed './configure', 'make' and 'make install' (while having 'xserver-xorg-video-tdfx-1.3.0' as 'CWD'). The only note is that I had to do all of them with 'sudo' cause all the files had root ownership, at least in my case.
-Follow the rest of cbrinegar's procedure up to the end.

-NOTE: I am using video with 1440x900 pix at 16bpp (didn't tried at 24bpp, but I bet it's not worthy.
Furthermore, it is assumed you already have 'glide3' installed. If not, you didn't have 3D acceleration anyway, so follow other tutorials in this forum to get the card working with OpenGL first.

Hope this to be useful for you! Thanks community !

Hello, I'm totally new to Ubuntu, just finished installing Ubuntu 8.04 LTS on a older computer and wanted to force myself into Ubuntu and stray away from the evil empire, lol, this being my first post, I have a Voodoo 5 5500 AGP video card installed, and the install went smooth as pie, but I'm stuck at 800 x 600 resolution, maybe that's an ok resolution, but could go higher, but I'm also stuck as to how to update to this tdfx driver and I'm also trying to install Unreal Tournament ( The origional retail CD ) and I'm way fresh to Ubuntu, need a little help if someone would not mind helping a newbie like myself.
Thanks for any help anyone would to give.
Glad to be here.

I just installed ubuntu 8.04 on an old IBM intellistation ZPRO. (866 Intel Pentium III Xeon processor) with 500mb's of ram, and a 3d Wildcat 4110 video card. The video card would only work in 640x480.. After searching all over the internet, and only finding posts from people saying they could not get any kind of drivers for the wildcat 4110, I replaced the wildcat card with an old 3dfx voodoo 3 3000. The system will now work in 800x600, but that's the best I can get.

I tried doing some of the fixes mentioned earlier in this thread, but they were on earlier versions of ubuntu.

I'm setting this system up for my 13 year old son.. for web browsing, listening to music and watching videos.. as well as IM and for him to do his homework. Ubuntu is running well on it..with all the current patches..

I'd just like to see if I can take better advantage of the video card.

Thanks in advance for any help anyone can provide.
