X- 3D support not working

antivoid · Guest

When I used redhat, 3D accelaration worked fine. However, on my fresh gentoo install it's not working. When I try to run xscreesaver progs that use 3D accelaration, I get the error "Xlib: extension "GLX" missing on display ":0.0"."
What's going on here? Did 3D support not get compiled into X? Any suggestions on how to get this working? (BTW, I'm using a Voodoo 3 card, if that helps any)

It turns out the line to load glx was commented out, but I fixed that. I tried to run the 3d screensavers, however they ran very slow. Its obvious that they're using a software renderer. I've eventried adding stuff like: GLcore, dbe, and dri and chainging the driver in my video section from vga to tdfx. No good. They're still not using acceleration. Help!

When you compiled your kde / gnome system you probably didn't have opengl in your use vars, this might be why they don't run with hardware rendering.
maybe re emerge your screensavers with opengl in your use vars?

Check if you have tdfx_dri.so in /usr/X11R6/lib/modules/,
if not add voodoo3 (for glide if you have voodoo3) and 3dfx (for xfree) to your USE in make.conf and recompile glide and xfree and you should be all set.

I have the same problem and it has me stumped. DRI does work fine on the same box with RedHat, similar to antivoid.

I believe I have all the right modules and XFree86 settings. However, I seem to have a problem with libvbe. Can someone confirm that this is breaking my DRI and perhaps suggest a resolution? I did a standard "emerge xfree86" to install. Do I need to recompile with a "vbe" in the USE flags??

antivoid, do you have a similar "vbe" error in your XFree86.0.log file?

Okay. This thing still isn't working. I added 3dfx and voodoo3 to my USE var and recompiled X. It now has a lib/modules/dri/tdfx_dri.so present. However when I try to run a GL xscreensaver module, it runs really slow and I get these two messages to console:
libGL error: failed to open DRM: operation not permitted
libGL error: reveting to (slow) inderect rendering
I have no idea what's going on here. And how do I even check if tdfx_dri is loaded? Also, Mr. Atoz, I don't have any error pretaining to vbe in my log.

I finally got it working. I did a google search on that error and I found this to add to my XF86Config:
Section "DRI"
Mode 0666
EndSection

Hope this also helps anyone else who is having troubles with 3d.
